>>>>>I don't think so and I have had others with this challenge. To be honest, editing in a grid can be complicated real easy. I rarely do it only because I don't like dealing with editing in grids. I prefer to provide editing forms. How do you have your in place editing setup? Are you using edit templates?

>>I just had a look at the telerik demo. Does that mean that in a one to many situation you let the user edit the many side, and then save just that record? What happens if the user makes a change on the many side and saves it, then wants to discard the overall changes?

>You can still treat that however the situation dictates. If you allow them to create an order, then add order items you then save the whole order and detail at the same time. If you wish the records to be added to the grid doesn't mean it has to be added to the table until you are ready.

OK. Any further ideas on displaying the icon?
