I have used this below table in this tutorial.

Now add some record to the table. Right click on the table => show table data => enter record.

Then right click on the AngularData Folder (Under scripts folder) => Add => New Item => choose JavaScript file (under the Web option) => enter the name (E.g. UniStudent.js) => and click Add button.

Right the following code in “UniStudent.js” file.

I have already discussed a little bit about Module, Controller, $scope, $http, Factory in previous tutorials.

ngroute: ngroute is an AngularJs module that helps you to make your application a Single Page Application. If you want to navigate to different pages in your application, you can do it easily without page reloading.

$watch: $watch is nothing but keeping track of (or watching) scope variables and the changes of their values. Simply it moniter your scope variables and their values. E.g. here we are watching our form variables and their values.

$q: $q is the service of AngularJs. It helps us to run asynchronous functions and use that functions return values when they are done processing.

$q.deffer(): $q.deffer() is used for signaling the successful completion or unsuccessful completion of a task. Simply it shows the status of task.

Step # 8 – Add server side validation to Model class

Now in this step we will add validation to our model class.

Go to solution explorer => open dropdown UniversityModel.tt under UniversityModel.edmx dropdown list => open student.cs class. You will see model properties in model class.

Add the following validations to your model class.

Note: – don’t forget to add System.ComponenetModel.DataAnnotations library in model class.
