Sory. I was looking for a Renderer property. I haven't noticed SetActiveRenderer() method, ofcource, it works fine.
Some other question:
1) Do you intend to make Renderer property visible in design-time? My point is, that if I had a few HeaderControls I would have to call SetActiveRenderer() for each of them. Yes, I am to lazy to code, I prefer clicking instead of coding :)
2) Other Sand controls have a cool feature that they change their colour automatically when the system colours change. Do you intend to include such feature for HeaderControl?
Best regards,
