Do this -- Before the collection changes -- store the id(not the selectedIndex) of the selectedItem in a temp variable. Now once collection changes -- find the index of the temp id stored above, in the collection (index of the previous selected Item) and make the datagrid's selectedIndex as the new index you found in previous step, using the code sent in my earlier reply.
