    Hi,

    Thank you very much. Your suggestion worked fine. Now I'm able to draw a gradient "backcolor".

    I have one problem though. It seems that the gradient "backcolor" is drawn on top of the buttons, because I'm not able to see any of the buttons after i have drawn the "backcolor". I guess I have to redraw the buttons in order to be able to view them.

    My original idea was to use a foreach an run through all the ToolbarButton's and redraw them. However, there is no refresh()-method or invalidate()-method.

    Any suggestions on how to solve this problem?

    Kind regards,
    Tonny

            // TODO: Add constructor logic here

            this.SetStyle(System.Windows.Forms.ControlStyles.UserPaint, true);
