Not very helpful I know, but I have an almost identical problem (except my grid is docked to the left of the user control). I notice at design time, whenever I click on the grid, the anchors are reset to top, left – If I manually change them back to top, left, bottom, right, it works fine until I next click on the grid in design time!
I’ll keep looking for a solution and will post if I find one. Would appreciate it if you also post should you find a solution.
