Hello all, My problem is the Grid View Update Event Args.

New Values collection is empty in the Row Updating event Handler. New Values contains the collection of values updated in the Grid View control.

It gets into the "On Row Updating" event just fine, but there are no New Values or Old Values. Regarding on the Grid View control's Row Updating event problem, it is the expected behavior because when we do not associate Grid View(or other ASP.

NET 2.0 databound control) with Data Source control, it won't automatically query and fill the parameters collection of the updating/deleting/... In such cases, we need to manually extract the field values from the Template control. In that case you can do it using the Extract Values From Cell method to make the New Values collection yourself.

The Grid View is bound to a strongly-typed collection, derived from Collection Base, through the control's datasource property at runtime.

I don't recall seeing it emphasized in the documentation, and these kinds of dependencies create annoying bugs.
