OleDbRowUpdatingEventHandler
This delegate represents the method that handles the
OleDbDataAdapter.RowUpdating event, which fires
for each row that’s updated (inserted, deleted, or
modified), just before the appropriate command is executed. This
event lets you inspect the row and skip or cancel processing using
the OleDbRowUpdatingEventArgs class.
public delegate void OleDbRowUpdatingEventHandler(objectsender, OleDbRowUpdatingEventArgse);
