>Did you ever get an answer for this? I'm having a similar issue. I have a date field in a gridview and I'm setting the date in Row_Updating. When I do a This.Save I get the same error. It seems like of the the rows contained null values to start with then saving the DataSet back with the same values shouldn't cause an error.
