Ahmad,

No, the DataBinding is NOT your problem. Updating the backend database from a DataSet that has been modified both manually and through data-bound controls works just fine. I've done it many times ... something else is wrong, but at this point I don't know what to suggest any more. If none of the things that I've suggested have worked, then I guess you need to try and focus more on *where* the problem is happening. Trace and step through your code and check your data both before and after you have made changes. Check and see what the RowState is before and after. Things like that ... I don't think I can offer any more suggestions unless I have more information.
