How to validate only rows that have changed using a provider?

Is there a way, using a ValidationProvider, to only validate rows of a data bound grid that have changed and ignore those that haven’t?  Right now it validates everything even if nothing changed.  When you factor in child tables which also get validated in the same fashion, it becomes a performance hit.  Suggestions?  Thanks in advance.

Can you provide more details?  At what level do you do the validation and how do you do it?

Found the solution:  Go through DataRows of each grid, determine if the row has been changed (by looking at the underlying datasource), and call the provider’s validate method on each row that has been changed.  I was originally calling it on the whole grid which causes the problem.  Thanks.
