Paint event is not firing

Yes, we have a custom implemetation of OnPaint that calls our OnRender method instead to provide extended double buffering. But if you want to do custom painting, you should do it in a renderer class for TabStrip. The renderer draws/measures every portion of a TabStrip and allows you to make a completely custom looking one if you desire. Renderers can be set to the TabStrip.Renderer property.

I’ve looked at what you have described, and I have actually done a little work in this class in the bast. However, it looks like this just deals with the TabStrip…correct? How can I do custom painting on the actual Page?

You can override the renderer's DrawTabStripPageBackground method to custom paint the page. The renderer works on the TabStrip and the pages.

Thanks! That's what I was missing!
