We are getting a problem whe reducing the size of the window in a GroupBar. The GroupBarItems are not redrawing correctly. We are drawing the background using a LinearGradientBrush.

System.Drawing.Drawing2D.LinearGradientBrush bUnselected = new System.Drawing.Drawing2D.LinearGradientBrush(new Rectangle(0, 0, 200, BUTTON_HEIGHT), Color.FromArgb(34, 33, 36), Color.FromArgb(37, 37, 39), System.Drawing.Drawing2D.LinearGradientMode.Vertical);

System.Drawing.Drawing2D.LinearGradientBrush bselected = new System.Drawing.Drawing2D.LinearGradientBrush(new Rectangle(0, 0, 200, BUTTON_HEIGHT), Color.FromArgb(60, 60, 60), Color.FromArgb(80, 80, 80), System.Drawing.Drawing2D.LinearGradientMode.Vertical);

Hi,

Thanks for that, it has sorted out my problem.

There looks to be a bug in there still. What I was doing was when creating a GroupBarItem I assigned it a brush, this seems to cause the problem. When I tried your way (ProvideBackgroundBrush event) everything worked fine.

Thanks for the help.
