Hi,
I'm trying to get optimum performance for a frequently updating grid. Using your Trader grid example, I've implemented the DrawClippedGrid method for drawing updated cells. This works great as far as performance is concerned, but there's a "flicker" occasionally when a cell updates. On another thread, there was a reply that mentioned something about drawing the clipped grid to a bitmap, then drawing the bitmap to the grid (but no code). I've tried to implement this solution, but cannot get it working. I've attached the code I'm using:
