    {
        this.Parent.Text = "CustomTabControl Disabled";
        return;
    }

    TabRenderer.DrawTabPage(e.Graphics, tabPageRectangle);
    TabRenderer.DrawTabItem(e.Graphics, tabItemRectangle1,
        tab1Text, this.Font, tab1Focused, tab1State);
    TabRenderer.DrawTabItem(e.Graphics, tabItemRectangle2,
        tab2Text, this.Font, tab2Focused, tab2State);
