I have a hierarchical grid with a nestedview template in one of the child grids. A couple of the grids have a cascading combo, where one combo triggers a postback so that the second combo can be populated with new data. The problem I have is that I'm getting a
error when the selected item of the first combo is changed.
I've looked around but haven't found the solution yet. I've had this issue before but can't remember how I solved it (or even if I did). I'm wondering in this instance if it's a RadGrid-specific issue. One option will be to handle the postback and repopulation (I'm assuming that it's the combos that are causing the problem) programmatically but I'm not sure how to do that when the combos are in an editform or in a grid contained in a nestedview template.
