Otherwise, it works fine, and now I have provider-independent event handlers available from the Db Data Adapter class (which is how Microsoft should have implemented them to begin with). ''' Public Delegate Sub Row Updating Event Handler(sender As Object, e As Row Updating Event Args) Public Module Db Data Adapter Extension Sub New() End Sub Private Function Get Event(event Name As String, type As Type) As Event Info Return type.
Get Event(event Name, Binding Flags.[Public] Or Binding Flags. Declared Only) End Function ''' Public Function Add Row Updated Handler(adapter As Db Data Adapter, handler As Row Updated Event Handler) As Boolean Dim upd Event As Event Info = Get Event("Row Updated", adapter.[Get Type]()) If upd Event Is Not Nothing Then Try If handler.
Fortunately Sql Data Adapter allows you to execute updates in batches. number of rows to be treated as a single batch via Update Batch Size property.
There are also two events associated with this that you can use � Row Updating and Row Updated. in the absence of batch update, both of these events are raised for each and every row being updated.
Sql Command command Type=2 status=0) The Row Updated event returns this output: event args: (command=System.
Sql Command command Type=2 records Affected=1 row=System.
I have tried to override On Row Updated in my custom control, but the breakpoint never gets hit.
A Grid View Updated Event Args object is passed to the event-handling method, which enables you to determine the number of rows affected and any exceptions that might have occurred.
You can also indicate whether the exception was handled in the event-handling method by setting the On Row Updated Row Canceling Edit On Row Canceling Edit Row Deleted On Row Deleted Row Deleting On Row Deleting Row Editing On Row Editing Row Updating On Row Updating Grid View Class System.
According to the docs, it cannot be used to "intercept" the update process and prevent the update command from being executed: command gets executed in any case.
Since this event is not well suited to client-side data-validation, what is a good (best practices) use of the event?
