Hi Andrew,
After reviewing your question, I'm still not clear on some points. So if
I've misunderstood anything, please feel free to post here.
By means of "rather than having to compare all values", do you mean change
the ConflictDetection property of ObjectDataSource to OverwriteChanges
instead of CompareAllValues?
I suggest you add the timestamp field to DataKeyNames of the data bound
control along with the primary key. Thus they will both be passed to the
Update method of ObjectDataSource. Then you can compare the timestamp with
the one stored in underlying DataTable to see if gets changed by someone
else.
Hope this helps. Please feel free to post here if anything is unclear.
Sincerely,
Walter Wang (
