I'm a bit lost on this one... when several cells in a FlexGrid are merged both row/col and rowsel/colsel are always pointing to just one of the cells that are part of the merged one, so if you change one of its properties you don't change it for all the cells.

I'd like to know how you'd solve this, since the only methods I can think of right now are using two for loops, or modifying the database fields where these properties are set and reload the grid, and maybe the people with more experience know of some other better way.
