        this->Parent->Text = "CustomTabControl Enabled";
    }
// Draw the tab page and the tab items.
protected override void OnPaint(PaintEventArgs e)
{
    base.OnPaint(e);

    if (!TabRenderer.IsSupported)
    {
        this.Parent.Text = "CustomTabControl Disabled";
        return;
    }

    TabRenderer.DrawTabPage(e.Graphics, tabPageRectangle);
    TabRenderer.DrawTabItem(e.Graphics, tabItemRectangle1,
