Step 4 of 5: Adding Code to the Project

In the last step, you added four items to the C1CoverFlow control and set the items’ properties. In this step, you’re going to create a C1CoverFlow.SelectedIndexChanged event handler and add code to the event handler that checks for the value of the C1CoverFlow.SelectedIndex property. The TextBlock control, which you added in Step 1 of 5: Creating the Project, will change its Text property string value when the user selects an album cover.

Complete the following steps:

In the Objects and Timeline panel, select C1CoverFlow1.
In the Properties panel, click the Events button .
Locate the C1CoverFlow.SelectedIndexChanged event handler and double-click inside its text box.

The C1CoverFlow1_SelectedIndexChanged event handler is added to your project.

Replace the code comment with the following code:

Visual Basic	Copy Code
If C1CoverFlow1.SelectedIndex = 1 Then TextBlock1.Text = "Deep Purple: Machine Head" ElseIf C1CoverFlow1.SelectedIndex = 2 Then TextBlock1.Text = "Deep Purple: Made in Japan" ElseIf C1CoverFlow1.SelectedIndex = 3 Then TextBlock1.Text = "Deep Purple: Perfect Strangers" Else TextBlock1.Text = Nothing End If

Visual Basic

Copy Code

If C1CoverFlow1.SelectedIndex = 1 Then
   TextBlock1.Text = "Deep Purple: Machine Head"
  
ElseIf C1CoverFlow1.SelectedIndex = 2 Then
   TextBlock1.Text = "Deep Purple: Made in Japan"
  
ElseIf C1CoverFlow1.SelectedIndex = 3 Then
   TextBlock1.Text = "Deep Purple: Perfect Strangers"
Else
TextBlock1.Text = Nothing
End If

C#	Copy Code
if (C1CoverFlow1.SelectedIndex == 1) { TextBlock1.Text = "Deep Purple: Machine Head"; } else if (C1CoverFlow1.SelectedIndex == 2) { TextBlock1.Text = "Deep Purple: Made in Japan"; } else if (C1CoverFlow1.SelectedIndex == 3) { TextBlock1.Text = "Deep Purple: Perfect Strangers"; } else { TextBlock1.Text = null; }

Copy Code

if (C1CoverFlow1.SelectedIndex == 1)
{
TextBlock1.Text = "Deep Purple: Machine Head";
}
             
else if (C1CoverFlow1.SelectedIndex == 2)
{
TextBlock1.Text = "Deep Purple: Made in Japan";
}
             
else if (C1CoverFlow1.SelectedIndex == 3)
{
TextBlock1.Text = "Deep Purple: Perfect Strangers";
}
             
else
{
   TextBlock1.Text = null;
}

In this step, you added an event handler and code to your project. In the next step, you’ll run program and see the results of this quick start topic.
