Prevent checkbox in grid from unchecking when a row is expanded.

Question

I have a grid with a child grid, and beside the button that expands it is a checkbox. Now when I check the checkbox and expand the row, all the checkbox that I have checked are now unchecked. How can I prevent this? I tried the detailDataBound API of grid but that seems to only work at initial expand.
