A LightSwitch Home Page

With a little code you can get LightSwitch to do almost whatever you want. For an application I am working on, I wanted a screen that would display information about the current user.

What is unique about this particular requirement, was that I wanted to display a page that was not associated with a Table of data. I just wanted a screen to show, and display code that I wrote.

The code will show the current user, if they are authenticated, and what the authentication type that the application is using.

Set Up Authentication in LightSwitch

First step, double-click on Properties in the Solution Explorer.

Next, select Access Control, Use Forms authentication and check the Granted for debug box.

When you Hit F5…

You will be able to create Users, and Roles.

Stop the application and return to Visual Studio.

Create The Page

In the Solution Explorer, right-click on Screens and select Add Screen…

Select New Data Screen
Enter HomePage for Screen Name
Click OK

When the screen opens up, click Add Data Item…

Select Local Property
Select String for Type
Enter Name for Name
Click OK

Name will show in the list.

Repeat the same process and add the following Properties:

FullName

IsAuthenticated

AuthenticationType

We do not need the standard Save and Refresh buttons on this page. Right-click on Screen Command Bar and select Delete.

Screen Command Bar will remain but the buttons will be deleted.

Drag and drop the Name field on the page.

You can also use the Add button to add the fields.

Repeat the process, adding all the other Properties.

Write Custom Code

Select Write Code then HomePage_Created.

The code window will show.

Add the following code:

    Microsoft.LightSwitch.Security.IUser currentUser = this.Application.User;
    if (currentUser != null)
    {
        this.Name = currentUser.Name;
        this.FullName = currentUser.FullName;
        this.IsAuthenticated = currentUser.IsAuthenticated.ToString();
        this.AuthenticationType = currentUser.AuthenticationType.ToString();
    }
