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.

How To Set The Value Property In AngularJS ng-options - initial selected value of a select element
 
02:25
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.

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.

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 Material Multiple Select Option
 
00:42
Angular Material Multiple 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. 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.

Bootstrap radio buttons in Angular
 
07:21
In this video we will discuss working with radio buttons in Angular Template Driven forms. We want to include "Gender" radio buttons in the Create Employee form. When we select employee "Gender" using the radio buttons, the selected gender value should reflect in the Angular generated form model. Also, we we click the "Save" button we want the selected gender value to be logged to the console. Please copy the HTML for radio buttons from our blog using the link below http://csharp-video-tutorials.blogspot.com/2017/12/bootstrap-radio-buttons-in-angular.html Code Explanation 1. The name attribute is required to group the radio buttons as one unit and make the selection mutually exclusive. Make sure both the radio buttons have the same value for the "name" attribute. Otherwise the radio button selection won't be mutually exclusive. 2. It is also important that you set the "value" attribute for each radio button. This value is posted to the server when the form is submitted. While we are here, let's also include a textbox to capture "Phone Number" and "Contact Preference" radio button.

Bootstrap checkbox in angular
 
06:16
In this video we will discuss 1 Working with a checkbox control in Angular Template Driven forms 2. How to have a checkbox checked by default 3. How to disable a checkbox Working with a checkbox in Angular is very similar to working with a radio button. We want to include "Is Active" checkbox in the Create Employee form as shown below. When we check the checkbox, "isActive" property should reflect in the Angular generated for model. Also, when we click the "Save" button we want the "isActive" property value to be logged to the console. To achieve this all you have to do is include the following HTML in create-employee.component.html file. Please replace [ with LESSTHAN symbol and ] with GREATERTHAN symbol [div class="form-group"] [div class="form-control"] [label class="checkbox-inline"] [input type="checkbox" name="isActive" [(ngModel)]="isActive"]Is Active [/label] [/div] [/div] If we include "checked" attribute on a checkbox, we expect checkbox to be checked by default when the form initially loads. But you will discover that is not the case. [input type="checkbox" name="isActive" [(ngModel)]="isActive" checked]Is Active However, if you remove the "ngModel" directive from the checbox, then it gets checked as expected. Notice the "ngModel" directive is removed from the checkbox. [input type="checkbox" name="isActive" checked]Is Active 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 "isActive" property in the component class and initialise it to true. isActive = true; At this point you will have "IsActive" checkbox checked by default when the form loads. Now, even if we remove the "checked" attribute from the checkbox 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 the checkbox to be checked by default, so remove the "checked" attribute and the "isActive" property from the component class. How to disable a checkbox : To disable a checkbox, use the disabled attribute [input type="checkbox" name="isActive" [(ngModel)]="isActive" disabled]Is Active Another important point to keep in mind. By default, disabled form controls are not included in the Angular auto generated form model. Since, the "Is Active" checkbox is disabled, it will not be included in the Angular generated form model. In our form, we do not want the checkbox to be disabled, so please remove the disabled attribute.

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.

Angular cli ng serve options
 
09:36
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.

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.

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

In this video, we will discuss angular ngSwitch directive. Let us understand switch case with an example. Switch case in angular is a combination of 3 directives 1. ngSwitch directive 2. ngSwitchCase directive 3. ngSwitchDefault directive Text version of the video http://csharp-video-tutorials.blogspot.com/2018/03/angular-switch-case-example.html Slides http://csharp-video-tutorials.blogspot.com/2018/03/angular-switch-case-example-slides.html Angular CRUD Tutorial https://www.youtube.com/playlist?list=PL6n9fhu94yhXwcl3a6rIfAI7QmGYIkfK5 Angular CRUD Tutorial Text Articles & Slides http://csharp-video-tutorials.blogspot.com/2017/12/angular-crud-tutorial.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 Consider the following department data. Depending on the employee's department id we want to display department name. departments: Department[] = [ { id: 1, name: 'Help Desk' }, { id: 2, name: 'HR' }, { id: 3, name: 'IT' }, { id: 4, name: 'Payroll' } ]; ngSwitch example : For example code please refer to our blog using the link below. http://csharp-video-tutorials.blogspot.com/2018/03/angular-switch-case-example.html Code Explanation 1. [ngSwitch]="employee.department". The expression (employee.department) returns department id (1, 2 , 3 etc) 2. [span *ngSwitchCase="1"] Help Desk [/span]. If the department id is 1, then this switchcase is executed and it displays Help Desk 3. [span *ngSwitchDefault] N/A [/span]. The default switch case is executed if the department id is not 1, 2, 3 and 4 4. Jus like ngIf and ngFor, the directives ngSwicthCase and ngSwitchDefault are also structural directives, hence they have an asterisk in front of them 5. If multiple ngSwitchCases match the switch expression value, then all those ngSwitchCases are displayed

Angular base href
 
07:18
In this tutorial we will discuss the significance of the base href element in Angular. When setting up routing in an angular application, the first step is to set the base path using the base href element. The base path tells the angular router, how to compose the navigation URLs. The browser uses the base href value to prefix relative URLs when referencing CSS files, scripts, and images. During development we usually set this to a single forward slash This means all the URLs will be relative to the root of the application. So when we navaigate to "/list", the path "/list" will be appended to root UR and the complete URL will be as shown below. Notice "/list" is relative to the root URL. http://localhost:4200/list Along the same lines, when we navigate to "/create", the complete URL is http://localhost:4200/create When we deploy our application to a server, we typically deploy it to a sub folder on the server. For example, if we are deploying our application in a sub-folder called "emp", then we set the base href element to /emp/ as This means all the URLs now will be relative to the "emp" base path and will be as shown below. http://serverName/emp/list http://serverName/emp/create During development we usually set base href element to a single forward slash. At this point, if we execute the following command, all the URLs will be relative to the root URL "http://localhost:4200" ng serve -o Also, on the "sources" tab in the browser developer tools, you will find all the Script, Images and Template files are relative to the root URL "http://localhost:4200" During development, if you want a different base path other than "/", simply execute the "ng serve" command with --base-href option set to your desired base path ng serve -o --base-href /emp/ At this point all the URLs will be relative to "http://localhost:4200/emp" as we have set the --base-href to /emp/. You can confirm this by looking at the URLs in the address bar and the "Sources" tab in the browser developer tools. On your local development machine, if you set the base href element in index.html to "/emp/" instead of a single "/" and if you run ng serve -o command without the "base-href" option you will not see anything on the browser. When you open the browser developer tools, you will see the JavaScript bundle files failed to load. To fix this execute ng serve command along with the base href option as shown below. ng serve -o --base-href /emp/ On your local development machine, if you set the base href element in index.html to a single forward slash and if you want to deploy your application on a server on sub-folder called "emp", then you will have to remember to update the base href element value in index.html to "/emp/". There are 2 ways we can do this. 1. Manually update the index.html file OR 2. Use the --base-href option along with the ng build command as shown below. This will update the "base href" element value index.html. ng build --base-href /emp/ Text version of the video http://csharp-video-tutorials.blogspot.com/2017/12/angular-base-href.html Slides http://csharp-video-tutorials.blogspot.com/2017/12/angular-base-href-slides.html Angular CRUD Tutorial https://www.youtube.com/watch?v=rJ9o4TyhSuo&list=PL6n9fhu94yhWUcq5Pc16uf8YKXoZ87Vh_ Angular CRUD Tutorial Text Articles & Slides http://csharp-video-tutorials.blogspot.com/2017/12/angular-crud-tutorial.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
