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 Sub OvalShape1_VisibleChanged(ByVal sender As Object, _
 ByVal e As System.EventArgs) 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

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;
    }
}
