Use the UpdateRow method to programmatically update the record at the specified index in the data source. This method is commonly used when you need to update a record from outside of the GridView control, such as from a different control on the page.
This method can be called only for the row that is currently in edit mode, or for a row that contains a two-way data-bound input control. For more information about two-way binding expressions, see Binding to Databases.
To specify whether page validation is performed before the update operation, use the causesValidation parameter. Calling this method also raises the RowUpdated and RowUpdating events.
