Rowupdated vs rowupdating

NET, the performed updates to the database one row at a time. When batch processing is disabled, the row being updated can be accessed using the Row property of the Row Updated Event Args class.

When updating a database with changes from a Data Set in previous versions of ADO. Therefore, only one event fire for the next row, until all of the rows are processed.

(Note, in the gridview the Enable View State="False" - if I set it to True I get the standard "Failed to load viewstate. error) One strange thing that I've noticed that makes me think it's a View State problem is that if I change the Command Name of the Update button to "Edit" that postback event does get captured in the Row Command event...

to modify update behavior before it happens, to provide additional handling when an update will occur, to retain a reference to an updated row, to cancel the current update and schedule it for a batch process to be processed later, and so on.

' Assumes that connection is a valid Sql Connection object.

Close() End If End Sub Private Shared Sub On Row Updated( _ sender As Object, args As Sql Row Updated Event Args) If args.

Fill(data Set, "This Table") Private Shared Sub Fill Error(sender As Object, _ args As Fill Error Event Args) If args.

Therefore, you should test for the optimum batch size setting before implementing your application. Errors are handled the same way in batch mode as they are when batch mode is disabled. Only rows that have been successfully processed in the database will be updated in the corresponding Data Row within the Data Table.
