Radgrid edit mode rocks with a special formtemplate, it this might be simple but cannot figure out. I need to be able to postback while in edit mode, i have 2 dropdownlists and need the second to be filled by the first while in edit mode. I can fill them to existing values but if a user need to change them they stay with existing values and don't change becuase of no postback. So basically if they pick another make I need the models to refresh themselves based on the make. If this is not possible in edit mode I will take it out to a panel and do it here.
