ItemCheck

The ItemCheck event fires after a user checks or unchecks an item's checkbox. To fire automatically the AutoPostBack property should be set to True.

The event handler receives two parameters:

1. The instance of the listbox firing the event

2. An event arguments parameter containing the following property:

• Item - the RadListBoxItem object that has just been checked/unchecked

protected void RadListBox1_ItemCheck(object sender, RadListBoxItemEventArgs e)
{
    Label.Text = e.Item.Text;
}   

Protected Sub RadListBox1_ItemCheck(sender As Object, e As RadListBoxItemEventArgs)
    Label.Text = e.Item.Text
End Sub
