This works great and I can do all functions, but I need/want to turn off "Event Validation" for the page.
When I turn off "Event Validation" and try to Edit or Add a new record I get the error "An entry with the same key already exists....". If I remove the valdation control the Grid will work . I don't understand what is happening with the Grid/Validator that would be causing this issue. Thank you.
