Optimistic Concurrency check box
Hi there,
I have question about 'Optimistic Concurrency check box' in SqlDataSource Advance option. Can anyone elaborate more in details what it does.

When you check that option, VWD generates a WHERE statement that includes all columns and their original values. This way, the UPDATE statement won't update a record if someone else has updated any of those columns since the last time you queried the record from the database.
