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() 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;
            }
        }
