Gridview rowupdating in asp
I have previously posted an article on how to insert new rows in database using a Grid View.In this article however, I'll show you how a Grid View control can be used to update (edit), delete and insert data in a remote SQL Server table. Attach the Grid View with the Sql Data Source control, the way we have shown the link above.You're accessing so many items without null checks that it could be any number of things. Are you sure all of the controls exist in the cells you're specifying?
