Step 3

The table opens in the Data Designer.


In this way we can add as many tables as we want to our application. Here I am adding only one table.

Now once again go to the Solution Explorer and right-click on Screen and choose "Add Screen".

 Select the "New Data Screen" from the Screen Template, under screen information, choose "Employee" under screen data and provide some name to the Screen and click the "OK" button.

Suppose I have chosen the CreateNewEmployee_Created method from the write code.

A ".cs" file will open that consists of the following code. You can provide further code for that screen.

using System;

using System.Linq;

using System.IO;

using System.IO.IsolatedStorage;

using System.Collections.Generic;

using Microsoft.LightSwitch;

using Microsoft.LightSwitch.Framework.Client;

using Microsoft.LightSwitch.Presentation;

using Microsoft.LightSwitch.Presentation.Extensions;


namespace LightSwitchApplication


    public partial class CreateNewEmployee


        partial void CreateNewEmployee_InitializeDataWorkspace(global::System.Collections.Generic.List<global::Microsoft.LightSwitch.IDataService> saveChangesTo)


            // Write your code here.

            this.EmployeeProperty = new Employee();



        partial void CreateNewEmployee_Saved()


            // Write your code here.





        partial void CreateNewEmployee_Created()


            // Write your code here.
