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.

angularjs search filter example angularjs search box example In this video we will discuss, how to implement search in Angular using search filter. As we type in the search textbox, all the columns in the table must be searched and only the matching rows should be displayed. Script.js : The controller function builds the model. var app = angular .module("myModule", []) .controller("myController", function ($scope) { var employees = [ { name: "Ben", gender: "Male", salary: 55000, city: "London" }, { name: "Sara", gender: "Female", salary: 68000, city: "Chennai" }, { name: "Mark", gender: "Male", salary: 57000, city: "London" }, { name: "Pam", gender: "Female", salary: 53000, city: "Chennai" }, { name: "Todd", gender: "Male", salary: 60000, city: "London" }, ]; $scope.employees = employees; }); HtmlPage1.html : [!DOCTYPE html] [html xmlns="http://www.w3.org/1999/xhtml"] [head] [title][/title] [script src="Scripts/angular.min.js"][/script] [script src="Scripts/Script.js"][/script] [link href="Styles.css" rel="stylesheet" /] [/head] [body ng-app="myModule"] [div ng-controller="myController"] Search : [input type="text" ng-model="searchText" placeholder="Search employees" /] [br /][br /] [table] [thead] [tr] [th]Name[/th] [th]Gender[/th] [th]Salary[/th] [th]City[/th] [/tr] [/thead] [tbody] [tr ng-repeat="employee in employees | filter:searchText"] [td] {{ employee.name }} [/td] [td] {{ employee.gender }} [/td] [td] {{ employee.salary }} [/td] [td] {{ employee.city }} [/td] [/tr] [/tbody] [/table] [/div] [/body] [/html] Styles.css : CSS styles to make the form look pretty. body { font-family: Arial; } table { border-collapse: collapse; } td { border: 1px solid black; padding: 5px; } th { border: 1px solid black; padding: 5px; text-align: left; } At the moment, the search is being done across all columns.

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 Tutorial 11 - ng-if Directive
 
04:33
In this tutorial, we are going to learn about ng-if directive in angularJS Ng-if is a built-in Angular directive for adding and removing content from the DOM. Ng-if is extremely handy for showing and hiding content on a page. Ng-if, like most built-in directives relies upon evaluating an expression as true or false. In the case of ng-if, if the expression evaluates false, it removes the element from the DOM entirely. If it’s true, the element gets recreated ng-show directive is also used to show or hide the content based on expression . So what is the difference between ng-if and ng-show directive. ng-show only show or hide the content on the bases of CSS properties, so it only handle the visibility of the HTML element but that element is still in DOM but in case of ng-if element is entirely created or removed from DOM. Why ng-if is good to use? Angular uses a digest loop to watch for changes in an app to make changes in the view or model (two-way data binding). Watches are expensive from a performance standpoint. By removing an element from the DOM, you remove all the watchers on those elements. Having few watches in an app generally allows it to run faster.

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.

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

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.

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
 
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. 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

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.

Angular dev build vs prod build
 
10:46
In this video we will discuss the differences between a development build and a production build in angular. To generate a development build we can use either ng build OR ng build --dev To generate a production build we use ng build --prod Here are some of the differences between a development build and a production build in angular. Source Maps : Development build generate Source Maps where as production build does not. What are Source Maps To improve the performance, the application's JavaScript and CSS files are combined and compressed. It is extremely difficult to debug those compressed files. A source map holds information about the original files and can be used to map the code within a compressed file back to it’s original position in a source file. So with the help of these source maps we can easily debug our applications even after the the files are compressed and combined. By default, a development build produce source maps where as a production build does not. However, we can change this default behaviour by using --sourcemaps option along with the ng build command. It's alias is -sm. The following command produces a development build without source maps as we have set -sm option to false ng build --dev -sm false On the other hand, if you want source maps along with your production build set -sm option to true as shown below. ng build --prod -sm true Extracts CSS : With the development build global styles are extracted to .js files where as with the production build they are extracted to .css files. To change this default behaviour use --extract-css option or it's alias -ec with the ng build command. The following command produces a development build with global styles extracted to .css file(s) instead of .js ones. ng build --dev -ec true Minification & Uglification : A Prod Build is both minified and uglified, where as a Dev Build is not. What is Minification The process of removing excess whitespace, comments, and optional tokens like curly brackets and semicolons is called Minification. What is Uglification The process of transforming code to use short variable and function names is called uglification. The minified and uglified version of the file is smaller in size than the full version, resulting in faster response times and lower bandwidth costs. If you look at the bundles generated by the prod build, you will notice that they are minified and uglified. Notice, extra whitespaces, comments, and optional tokens like curly brackets and semicolons are removed. Also notice, the code is transformed by using short variable and function names. On the other hand, the bundles generated by the dev build, are not minified and uglified. Tree Shaking : A Prod build is Tree Shaked, where as a Dev build is not. What is Tree Shaking Tree shaking is the process of removing any code that we are not actually using in our application from the final bundle. It's one of the most effective techniques to reduce the application size. If you look at the bundles generated by the production build, they are significantly less in size compared with the bundles generated by the development build. This is beacause with the production build the code is tree shaked to remove dead code i.e the code that is not referenced by the application. Ahead-of-Time (AOT) Compilation : With a production build we get AOT (Ahead-of-Time) compilation, i.e the Angular component templates are pre-compiled, where as with a development build they are not. We will discuss Ahead-of-Time compilation in detail in our next video. The following table summarises the differences between a development build and a production build Feature Development Build Production Build Source Maps Yes No Extracts CSS .js file .css file Minifaction No Yes Uglification No Yes Tree Shaking No Yes AOT No Yes Text version of the video http://csharp-video-tutorials.blogspot.com/2017/11/angular-dev-build-vs-prod-build.html Slides http://csharp-video-tutorials.blogspot.com/2017/11/angular-dev-build-vs-prod-build-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
