The SendToBack method can be used to position a LineShape, OvalShape or RectangleShape control behind of all other line and shape controls on a given container. It does not position the control in front of other types of controls on the container; graphics drawn with line and shape controls always appear behind the other controls.
The following example demonstrates how to use the SendToBack method to change the z-order of shapes at run time. This example requires that you have a RectangleShape control named RectangleShape1 and an OvalShape control Named OvalShape1 on a form. For best results, make the controls different colors and make sure that they overlap each other.
Private Sub Shapes_Click(
ByVal sender As System.Object,
ByVal e As System.EventArgs
) Handles RectangleShape1.Click, OvalShape1.Click
' Send the control that was clicked to the bottom of the z-order.
sender.SendToBack()
End Sub
private void Shapes_Click(System.Object sender, System.EventArgs e)
{
// Send the control that was clicked to the bottom of the z-order.
((Shape)sender).SendToBack();
}
