When one or more rows are selected in a RadGridView, their cell backgrounds change to (by default) a pale orange color, with gradation I think.  But, when this happens, the backgrounds of those cells of the selected rows that are in GridViewCheckBoxColumns remain white.  I want to show the row selection color in the GridViewCheckBoxColumn cells, to make them consistent with the other cells in the selected rows.

I think the problem is that the embedded CheckBox completely fills the cell, obscuring the cell background proper.  If that is the case, then perhaps a solution would be to set the CheckBox's own background to transparent, so that the underlying cell color changes (when the row is selected and deselected) would be visible. 

If all that is true, then what I specifically want to know is how to set the background color of the embedded CheckBox in every cell of every GridViewCheckBoxColumn in the grid to transparent when the grid is shown.

Thanks, Stefan. Sorry to be so late replying.  Forum thread tracking is not working for me, so I did not see your post at the time.  And, for reasons unrelated to this thread but to do with specific application requirements, we have decided not to implement the check boxes in the grids with GridViewCheckBoxColumn.  Instead, we have developed our own unsophisticated alternative that will meet our needs.

So we have not implemented your solution in our application.  However, I have looked at and ran your sample application.  It does exactly what I was asking for.

Your sample provides solutions for both GridViewCheckBoxColumn and Checkbox.  They both work.  Our application's grids have many check boxes.  We did try implementing them with Checkbox but encountered slow grid building and scrolling performance.  There were no such performance problems with either GridViewCheckBoxColumn or our light-weight custom solution.  I mention this not at all as a criticism of the solution sample, but just as something anyone implementing a RadGridView with many check boxes should consider.

Cheers, Simon
