Examples

The following example shows how to respond to the BackColorChanged event in an event handler. This example requires that you have a RectangleShape control named RectangleShape1 on a form.

Private Sub RectangleShape1_BackColorChanged(
  ) Handles RectangleShape1.BackColorChanged

    ' The BackStyle must be Opaque or the BackColor has no effect. 
    If RectangleShape1.BackStyle = BackStyle.Transparent Then
        RectangleShape1.BackStyle = BackStyle.Opaque
    End If 
End Sub

private void rectangleShape1_BackColorChanged(object sender, System.EventArgs e)
{
    // The BackStyle must be Opaque or the BackColor has no effect. 
    if (rectangleShape1.BackStyle == BackStyle.Transparent)
    {
        rectangleShape1.BackStyle = BackStyle.Opaque;
    }
}
