Examples

The following example shows how to respond to the VisibleChanged event in an event handler. This example requires that you have an OvalShape control named OvalShape1 and a RectangleShape named RectangleShape1 on a form.

private void ovalShape1_VisibleChanged(object sender, System.EventArgs e)
{
    // Switch between the oval and rectangle shapes.
    if (ovalShape1.Visible == false)
    {
        rectangleShape1.Visible = true;
    }
    else
    {
        rectangleShape1.Visible = false;
    }
}

Private Sub OvalShape1_VisibleChanged() Handles OvalShape1.VisibleChanged
    ' Switch between the oval and rectangle shapes.
    If OvalShape1.Visible = False Then
        RectangleShape1.Visible = True
    Else
        RectangleShape1.Visible = False
    End If
End Sub
