Step 1 : Create the Department class. Add a TypeScript file to the models folder. Name it department.model.ts. Copy and paste the following code. Notice the Department class has 2 properties - id and name of the department. export class Department { id: number; name: string; } Step 2 : Import the Department class. Include the following import statement in create-employee.component.ts file import { Department } from '../models/department.model'; Step 3 : Include the following array of departments in CreateEmployeeComponent class in create-employee.component.ts file departments: Department[] = [ { id: 1, name: 'Help Desk' }, { id: 2, name: 'HR' }, { id: 3, name: 'IT' }, { id: 4, name: 'Payroll' } ]; Please note : The "Department" type is not required for the application to work, but it adds great value during development. Using it provides us intellisense, error checking and type saftey. For the HTML used in the video, please refer to my blog link below http://csharp-video-tutorials.blogspot.com/2018/01/angular-select-options-from-array.html Code explanation: 1. On the "option" element we are using ngFor structural directive to loop over the array of departments we have in the "departments" property of the component class 2. For each "Department" object in the "departments" array, we get an option. 3. The option value is the department id and the display text is the department name 4. Notice the square brackets around the [value] property. This is property binding in Angular. We discussed property binding in detail in Part 9 of Angular 2 tutorial. If you remove the square brackets the value for each option will be the literal text "dept.id" instead of the department id (1 or 2 or 3 etc.) Property binding in Angular https://www.youtube.com/watch?v=RGYfTx9AAQA&list=PL6n9fhu94yhWqGD8BuKuX-VTKqlNBj-m6&index=9 5. To display the deprtment name we are using interpolation. We discussed interpolation in Part 8 of Angular 2 tutorial. Interpolation in Angular https://www.youtube.com/watch?v=2FkkAqFWRk8&list=PL6n9fhu94yhWqGD8BuKuX-VTKqlNBj-m6&index=8 6. Since ngFor is a structural directive there is an asterisk before it. 7. Structural directives modify the DOM, i.e they add or remove the elements from DOM. Adding and removing elements from DOM is different from showing and hiding. We will discuss all these in detail in our upcoming videos. At this point, when we select a department, the respective department id is included in the Angular generated form model. Along the same lines, when we click the "Save" button the respective department id is logged to the console. Please note : It is important that we include the ngFor directive on the element that we want to be repeated. In our case we want an option element for each department we have in the array. So we included the ngFor directive on the option element. If we instead include the ngFor directive on the "div" element that has the bootstrap "form-group" class, we get 4 department dropdownlists. That is one for each department in the array. So it is important we include the ngFor directive on the right element.

Please visit http://technomark.in/How-To-Set-The-Value-Property-In-AngularJS-ng-options.aspx for more information. Here we explain how to Set The Value Property for ng-options. In latest version of AngularJS, this can be achieved by using track by expression. We can set the actual value for the value attribute of select element. Let ArrayData be the datasource and ScopeObject is the scope object attached. On ArrayData, the Value Field is DisplayID and Text Field is DisplayText. Then inside select statement, we can use ng-option as follows. ng-options = " data.DisplayText for data in ScopeObject.ArrayData track by data.DisplayID" Here we have used the track by data.DisplayID. By this way we can Set The Value Property for ng-options.

Angular Material Select Option
 
04:15
Angular Material Select Option.mat-select is a form control for selecting a value from a set of options, similar to the native select element. You can read more about selects in the Material Design spec. It is designed to work inside of a mat-form-field element. To add options to the select, add mat-option elements to the mat-select. Each mat-option has a value property that can be used to set the value that will be selected if the user chooses this option. The content of the mat-option is what will be shown to the user.

Working with a select list in Angular Template Driven forms 2. How to have one of the select list option selected by default 3. How to disable select list Let us understand working with a select element in Angular with a simple example. We want to include "Department" select list. For the HTML used in the demo, please refer to my blog using the link below http://csharp-video-tutorials.blogspot.com/2018/01/angular-bootstrap-select-list.html At the moment, we have hard coded the select list options in the HTML. In our next video we will discuss, how to get the select list options from the component class. Notice each option also has a corresponding value. The value is the department id which is what we want to save in the database table when the form is submitted. We will discuss, saving the data to a database table in a later video. At this point, when we select an option, the corresponding option value is included against the "department" property in the Angular auto-generated form model. Also when we click the "Save" button, the "department" property along with the selected option value is logged to the console in browser developer tools. How to have one of the select list option selected by default If we include "selected" attribute on one of the options of the select list, we expect that option to be selected by default when the form initially loads, but when the form reloads, the respective option will not be selected. If you remove the "ngModel" directive from the select list, then the the option gets selected as expected. In Angular, we use "ngModel" directive for two-way data binding. So the moment we put it back in place the "selected" attribute does not work. To make it work include "department" property in the component class and initialise it with one of the option value which you want to have selected by default. In our case, we want the "IT" option to be selected by default. The "IT option value is "3". So, I have initialised "department" property with a value of '3' department = '3' At this point you will have "IT" option selected by default when the form loads. Now, even if we remove the "selected" attribute from the "IT" option, it is still selected by default when the form loads. This is because of the two-way data binding that we get with "ngModel" directive. How to disable a select list : To disable a select element, use the disabled attribute Another important point to keep in mind. By default, disabled form controls are not included in the Angular auto generated form model. Since, the "department" select element is disabled, it will not be included in the Angular generated form model. In our form, we do not want the select element to be disabled, so please remove the disabled attribute. Also, we do not want any option to be selected by default, so remove the "department" property from the component class. In our next video, we will discuss, how to get the select list options from the component class, instead of having them hard-coded in the HTML.

You can read more about selects in the Material Design spec. It is designed to work inside of a mat-form-field element. To add options to the select, add mat-option elements to the mat-select. Each mat-option has a value property that can be used to set the value that will be selected if the user chooses this option. The content of the mat-option is what will be shown to the user. mat-select defaults to single-selection mode, but can be configured to allow multiple selection by setting the multiple property. This will allow the user to select multiple values at once. When using the mat-select in multiple selection mode, its value will be a sorted list of all selected values rather than a single value.

ng hide and ng show in AngularJS
 
06:38
In this video we will discuss ng-hide and ng-show directives in Angular with examples ng-hide and ng-show directives are used to control the visibility of the HTML elements. Let us understand this with an example When Hide Salary checkbox is checked, the Salary column should be hidden, when it is unchecked the Salary column should be unhidden Script.js : The controller function builds the model var app = angular .module("myModule", []) .controller("myController", function ($scope) { var employees = [ { name: "Ben", gender: "Male", city: "London", salary: 55000 }, { name: "Sara", gender: "Female", city: "Chennai", salary: 68000 }, { name: "Mark", gender: "Male", city: "Chicago", salary: 57000 }, { name: "Pam", gender: "Female", city: "London", salary: 53000 }, { name: "Todd", gender: "Male", city: "Chennai", salary: 60000 } ]; $scope.employees = employees; }); HtmlPage1.html : Notice ng-model directive on the checkbox is set to hideSalary. hideSalary variable is then used as the value for ng-hide directive on the th and td elements that displays Salary. When the page is first loaded, hideSalary variable will be undefined which evaluates to false, as a result Salary column will be visible. When the checkbox is checked, hideSalary variable will be attached to the $scope object and true value is stored in it. This value is then used by the ng-hide directive to hide the salary td and it's th element. When the checkbox is unchecked, false value is stored in the hideSalary variable, which is then used by the ng-hide directive to display the Salary column.

How to get the value of an HTML dropdown with Angular - Kevin Chisholm Video
 
04:02
https://blog.kevinchisholm.com In this video, I’ll explain how to get the value of the selected drop down with Angular. When working with Angular, you may find that at times you need to act upon the selection a user makes from a drop down box. Technically a drop down box is what’s called a select element. And here in this page I’ve got a select element, otherwise known as a drop down box, with the five days of the work week. So, when I select one of the days, the result of that selection is shown in the page. If I choose Monday I see Monday, if I choose Tuesday I see Tuesday, and so forth. So, the main thing to keep in mind here is that whatever the user selects, we’re acting upon that value. In this case we’re showing it in the page, but we may want to do something more sophisticated. Let’s take a look at the code and see how this all works. So here we have the markup for the exact page that we just looked at. And the select element is the drop down box that you see. Now when the user makes a selection, they are choosing one of these option elements. And each time they choose an option element, the change event fires on the select element. When the change event fires, we’re executing the select change handler method on our component, and passing it the event object. We’ll revisit this in just a minute. Down here, we’re showing the value of the selected day property. So we just know that on our component there’s a property called selected day, and when you saw me making a change here in the drop down box, right here, the selected day property is what’s being updated here in that page. So let’s look at our component. So here in the component, we have this selected day property and it’s a string, so that’s the property that we’re updating whenever we make a change to the drop down box. Here we have the select change handler method, and that method takes an event object as its sole argument. An event object is something that the browser provides to an event handler, which allows you to drill down, act upon different parts of the event. But just know that when we get this event object, it has a target property. The target property is the element upon which the user acted, so in this case it’s the select element, and the value is the value that’s produced by that other value of that element. So in this case, when the user makes change to the select element, whatever option they chose, that’s the value. If they chose Monday, the value’s Monday. If they chose Tuesday, the value is Tuesday, and so forth. So we’re setting that to this .selectedday, and this .selectedday is the selectedday property. We just have to refer to it as this .selectedday, because we’re inside of an event handler. But the main thing to know is that when this event handler executes, it takes a look at this even object, it takes a look at its target property, and then it takes a look at that target property’s value property and assigns it to the selected day property of this component. And what that all translates to is that any time the user makes a change here, the change event fires, our event handler is executed, and its passed the event object, and whichever option they chose, the value that they chose will wind up being the target value property and that’s passed to selected day. Selected day is down here, so what happens is we see the result of the user’s action here in the page.

Angular value vs ngvalue
 
08:59
In this video we will discuss how to validate a select element if it has a custom option like "Please Select" etc. Along the way we also discuss the difference between value and ngValue in Angular. If you use value, null is treated as a string and not as a null. Hence the required validation does not work. If you just want the selected value as a string then use value property. If you want the selected object from the SELECT element, then use ngValue. Use the disabled attribute, if you do not want the user to be able to select the first default option. The built-in required validator will only work with the SELECT element, if the default option value is null.

Angular radio button checked by default
 
04:59
In this video we will discuss 1. How to have a radio button checked by default 2. How to disable a radio button If you need the code samples used in the demo, you may copy them from our blog using the link below. http://csharp-video-tutorials.blogspot.com/2018/01/angular-radio-button-checked-by-default.html If we include checked attribute on a radio button, we expect that radio button to be checked by default when the form initially loads. But you will discover that is not the case. In the following example, we have included "checked" attribute on "Male" radio button, but when the form is displayed it is not checked. [input type="radio" name="gender" value="male" [(ngModel)]="gender" checked] However, if you remove the "ngModel" directive from the radio button, then it gets checked as expected. Notice the "ngModel" directive is removed from the radio button. [input type="radio" name="gender" value="male" checked] With Angular Template Driven forms, we use "ngModel" directive for two-way data binding. So the moment we put it back in place the "checked" attribute does not work. To make it work include "gender" property in the component class and initialise to the value of the radio button that you want to have checked by default. In our case, let us say, we want the "Male" radio button to be checked by default. To achieve this include "gender" property initialised to value of "male" in the component class as shown below. gender = 'male'; At this point you will have "Male" radio button checked by default when the form loads. Now, even if we remove the "checked" attribute from the "Male" radio button it is still checked by default when the form loads. This is because of the two-way data binding that we get with "ngModel" directive. For our form we do not want any radio button to be checked by default, so remove the "checked" attribute and the "gender" property from the component class. How to disable a radio button : To disable a radio button, use the disabled attribute on that radio button. "Male" radio button in this case will be disabled when the form initially loads. [input type="radio" name="gender" value="male" [(ngModel)]="gender" disabled] Another important point to keep in mind. By default, disabled form controls are not included in the Angular auto generated form model. Since, the "Male" radio button is disabled, the gender property will not be included in the Angular generated form model. In our form, we do not want any radio button to be disabled, so please remove the disabled attribute. In our next video, we will discuss working with CheckBox control in Angular Template Driven forms.

How to get the value of the selected HTML radio button with Angular - Kevin Chisholm Video
 
04:50
https://blog.kevinchisholm.com In this video, I’ll explain how to get the value of the selected radio button with Angular. When working with Angular, you may find that you need to act upon the choice that a user makes with a set of radio buttons. So here I’ve got a set of radio buttons, and when the user selects one of the radio buttons, I’ve showed the result in the page. So bottom line is that whenever the user makes a selection here, I’m acting upon the value of the selection they’ve made. If I choose Monday, I see Monday, and Tuesday, and so forth. Let’s take a look at how this all works. So here we have the code that produces the exact page that you just saw. Now I’m using an ngFor, which is used to iterate over an array. So I’m saying let day of days. Well what is days? Well days in our component file is an array and this array is the five days of the work week. So just know that in our template, we’re saying hey, for every day in the days array, for every day in that work week, we’re going to do this. This div is going to happen five times. And each time it happens, we’re going to get a different day and we’re going to produce a radio button. So that’s just an easy way of creating five radio buttons, as opposed to creating five, literally five input elements type of radio in the markup. We just create one, and use ngFor to loop through it. Now for each radio button we’re looking at the change event and we’re saying, hey, when the change happens on this radio button, we want to call the radio change handler. That’s an event handler. And we’re passing it an event object. So just know that when one of these radio buttons changes, this radio change handler method is called and passed to the event object. Then down here on the page, this selected day property is going to be updated, and the selected day property is what you see when the user makes a change here. This is the selected day property. This is what’s being updated. So let’s take a look at our components and see how this all comes together. So in the component file, we know that we have our days array, which produces the five days of the work week. But here we have our radio change handler, and that’s the event handler that gets executed when the user makes a selection, or changes one of the radio buttons. And it receives an event object. An event object is an object that’s provided by the browser, whenever an event handler is executed. So, let’s drill down and inspect and act upon different properties of the event. In this case, the event will have a target. The target is the element that was acted upon. So the target is going to be the radio button that was changed. And the value is the value of that radio button. For example, Monday, Tuesday, Wednesday, Thursday, and Friday. So we’re saying that this .selectedDay = that value. While selectedDay is a property on our component, and that’s what we were looking at just a few moments ago, here. We were saying that selectedDay is the property provided in a template that allows us to see in the web page the change that is made. So back in the component, we just know that when the event handler fires, it receives an event object, it looks at its target property, and then the value of the target property, for example, Monday, Tuesday, Wednesday, Thursday, Friday, and it assigns it to this .selectedDay. We have to say this .selectedDay because we’re inside of a method here, but this .selectedDay is the selectedDay property. So all that winds up coming together here in the template, in that we create five radio buttons, and then for each radio button whenever one of them changes, we call this event handler, we pass it the event object, and then our component acts upon that event object, takes a look at its target, and the target’s value, and assigns it to this. selectedDay. selectedDay is a property in our component, and then back in the template, we see the update to selectedDay. And then in the browser, what happens is, whenever we make a selection, the value of that selection is shown in the web page, whether it’s Monday, Tuesday, Wednesday, and so forth.

Sorting data in AngularJS
 
08:32
angularjs order data angularjs orderby filter example angularjs ng-repeat orderby example angularjs filter orderby date angularjs orderby reverse angularjs orderby ascending angularjs filter orderby descending Sorting data in AngularJS In this video we will discuss how to implement sorting in AngularJS. This is continuation to Part 8. Please watch Part 8 from AngularJS tutorial for beginners before proceeding. To sort the data in Angular 1. Use orderBy filter {{ orderBy_expression | orderBy : expression : reverse}} Example : ng-repeat="employee in employees | orderBy:'salary':false" 2. To sort in ascending order, set reverse to false 3. To sort in descending order, set reverse to true 4. You can also use + and - to sort in ascending and descending order respectively Example : ng-repeat="employee in employees | orderBy:'+salary'" Let us understand sorting data with an example. The dropdownlist shows the columns and the direction we want to sort When a dropdownlist item is selected, the table data should be sorted by the selected column Script.js : The controller function builds the model. Also sortColumn property is added to the $scope object. Notice sortColumn property is initialized to name. This ensures that the data is sorted by name column in ascending order, when the form first loads. var app = angular .module("myModule", []) .controller("myController", function ($scope) { var employees = [ { name: "Ben", dateOfBirth : new Date("November 23, 1980"), gender: "Male", salary: 55000 }, { name: "Sara", dateOfBirth: new Date("May 05, 1970"), gender: "Female", salary: 68000 }, { name: "Mark", dateOfBirth: new Date("August 15, 1974"), gender: "Male", salary: 57000 }, { name: "Pam", dateOfBirth: new Date("October 27, 1979"), gender: "Female", salary: 53000 }, { name: "Todd", dateOfBirth: new Date("December 30, 1983"), gender: "Male", salary: 60000 } ]; $scope.employees = employees; $scope.sortColumn = "name"; }); HtmlPage1.html : The select element, has the list of columns by which the data should be sorted. + and - symbols control the sort direction. When the form initially loads notice that the data is sorted by name column in ascending order, and name option is automatically selected in the select element. Notice the orderBy filter is using the sortColumn property that is attached to the $scope object. When the selection in the select element changes, the sortColumn property of the $scope object will be updated automatically with the selected value, and in turn the updated value is used by the orderBy filter to sort the data.

AngularJS ng repeat directive
 
11:04
angularjs ng-repeat example ng-repeat simple example ng-repeat simple array angularjs ng repeat nested array angularjs ng repeat index example In this video we will discuss 1. ng-repeat directive in Angular 2. Nesting ng-repeat with an example ng-repeat is similar to foreach loop in C#. Let us understand this with an example. Here is what we want to do. 1. For each employee we have in the employees array we want a table row. With in each cell of the table row we to display employee Firstname Lastname Gender Salary This can be achieved very easily using ng-repeat directive. HtmlPage1.html : In the view, we are using ng-repeat directive which loops thru each employee in employees array. For each employee, we a get a table row, and in each table cell of the table row, the respective employee details (Firstname, Lastname, Gender, Salary) are retrieved using the angular binding expression. Nested ng-repeat example : The model contains an array of countries, and each country has an array of cities. The view must display cities nested under their respective country. Finding the index of an item in the collection : To find the index of an item in the collection use $index property To get the index of the parent element Use $parent.$index or Use ng-init="parentIndex = $index" Link for all dot net and sql server video tutorial playlists https://www.youtube.com/user/kudvenkat/playlists?sort=dd&view=1 Link for slides, code samples and text version of the video http://csharp-video-tutorials.blogspot.com/2015/11/angularjs-ng-repeat-directive.html

AngularJS Tutorial #12 - ng-show directive
 
05:19
Yo ninjas, in this AngularJS tutorial, I'll show you how we can dynamically hide and show elements depending on the value of certain properties in your data. ng-show only shows elements when it is equal to true, and ng-hide only hides elements when it is equal to true. Hey gang, in this AngularJS tutorial, I'll be introducing you to filters and how we can use them to change the way our data is displayed to a user. Filters can be used in conjunction with ng-repeat, or directly on the expression itself. We use Angular filters to do things like ordering a list of items alphabetically, or by type, or to display numbers as a currency. ----- COURSE LINKS: + Source files on GitHub - https://github.com/iamshaunjp/angular-js-playlist + Atom text editor - https://atom.io/ --------------------------------------------------------------------------------------------- You can find more front-end development tutorials on CSS, HTML, JavaScript, jQuery, WordPress & more on the channel homepage...

Angular cli ng serve options

In this video we will discuss some of the common options that we can use with ng serve command. To see the list of all options that we can use with "ng serve" command use --help option ng serve --help The following page also shows all the options that can be used with ng serve https://github.com/angular/angular-cli/wiki/serve The following command, builds and launches the application in your default browser. ng serve --open Many of our channel subscribers have sent me emails saying their application is using Internet Explorer, but they want to use Google chrome instead. So thier question is how to change my default browser. Well that's simple and it really depends on the operating system you have. For example, on a Windows 7 operatin system here are the steps to change your default browser. 1. Click on the Windows Start Button and in the "Search programs and files" text box type: Control 2. Control Panel would appear in the list. Click on it. 3. In the "Control Panel" window, click on "Default Programs" 4. In the "Default Programs" window, click on "Set your default programs" 5. In the list of programs that appear, select the "Browser" that you want to be the default browser and then click on the link that says "Set this program as default" That's it. At this point, execute "ng serve --open" command and you will have your application launched in your specified default browser. Instead of using the full option name --open, you can also use it's alias -o The following table shows the common options, alias, default value and their purpose Option Alias Default Purpose --watch -w true Run build when files change --live-reload -lr true Whether to reload the page on change --open -o false Opens the url in default browser --port -p 4200 The port on which the server is listening --extract-css -ec Extract css from global styles onto css files instead of js ones Text version of the video http://csharp-video-tutorials.blogspot.com/2017/11/angular-cli-ng-serve-options.html Slides http://csharp-video-tutorials.blogspot.com/2017/11/angular-cli-ng-serve-options-slides.html Angular CLI Tutorial https://www.youtube.com/watch?v=rJ9o4TyhSuo&list=PL6n9fhu94yhWUcq5Pc16uf8YKXoZ87Vh_ Angular CLI Text articles & Slides http://csharp-video-tutorials.blogspot.com/2017/10/angular-cli-tutorial-for-beginners.html All Dot Net and SQL Server Tutorials in English https://www.youtube.com/user/kudvenkat/playlists?view=1&sort=dd All Dot Net and SQL Server Tutorials in Arabic https://www.youtube.com/c/KudvenkatArabic/playlists
