.
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 SelectedIndexChanged event handler and add code to the event handler that checks for the value of the 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:
1. In the Objects and Timeline panel, select C1CoverFlow1.
2. In the Properties panel, click the
Events button .
3. Locate the SelectedIndexChanged event handler and double-click inside its text box.
The C1CoverFlow1_SelectedIndexChanged event handler is added to your project.
4. Replace the code comment with the following 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#
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.
