Performance issue with Grid 3.7 and tabcontrol

Hi,

 I have an application that uses several grids with a tab control. In that scenario I have a real performance issue when switching between when I have changed the background and foreground color of several cells.

So, if I switch between tabs with the default colors, it switches fast, but when I change the color of some cells, the switch becomes really slow. The more I change, the slower it gets, and when I reset them back to the default color, the performance improves. 

Is there a way I can override the paint method on those cells? Will that actually improve performance? or are there other events I need to be aware of?

Ok. I implemented my own class to mimic the functionality of a tab control, and found that the problem also happens when you make a Grid invisible, and then visible. So at this time, I opted to keep them all visible and pile them up on top of each other, using BringToFront to keep the selected grid visible. No performance issues that way..
