Note

Do not try to set focus in the LostFocus event handler. Doing so can cause your application or the operating system to stop responding.

Examples

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

private void rectangleShape1_LostFocus(object sender, System.EventArgs e)
{
    // Restore the default BorderColor.
    rectangleShape1.BorderColor = SimpleShape.DefaultBorderColor;
}

Private Sub RectangleShape1_LostFocus() Handles RectangleShape1.LostFocus
    ' Restore the default BorderColor.
    RectangleShape1.BorderColor = 
      PowerPacks.SimpleShape.DefaultBorderColor
End Sub
