UniRowUpdatingEventHandler Delegate

Represents the method that will handle the UniDataAdapter.RowUpdating event of an UniDataAdapter.

[Visual Basic]
Public Delegate Sub UniRowUpdatingEventHandler( _
   ByVal sender As Object, _
   ByVal e As RowUpdatingEventArgs _
) 

[C#]
public delegate void UniRowUpdatingEventHandler( 
   object sender,
   RowUpdatingEventArgs e
);

Parameters

sender

The source of the event.

e

The UniRowUpdatingEventArgs that contains the event data.

Remarks

The handler is not required to perform any action, and your code should avoid generating exceptions or allowing exceptions to propagate to the calling method. Any exceptions that do reach the caller are ignored.

Use the handler to process UniRowUpdatingEventArgs and to specify how updates are processed. For example, you may opt to skip the update of the current row or skip the update of all remaining rows. Note that the rows are updated in the order that they were received from the database.

When you create an UniRowUpdatingEventArgs delegate, you identify the method that will handle the event. To associate the event with your event handler, add an instance of the delegate to the event. The event handler is called whenever the event occurs, unless you remove the delegate. For more information about event handler delegates, see "Events and Delegates" in the .NET Framework SDK documentation.
