I have a client you is wanting an internal messaging(or email like) system added to their product. The problem we are running into is sending messages to mutilble users(see screen shot). The last three messages were all sent as one message, is there any way to group these messages into one line using the radgrid without using the grouping already built into radgrid? Example: the sent to column would show a string of the the users names and the rad grid would show that message as one messge.
