or you can just set the Event Type happening, before Update and you are all set 
Example:
this.oTrans.SetCurrentEvent(TransactionEvent.UpdateOnRowChange);
this.oTrans.Update();
Example to set it to None, so none of the Dialogs appear even if the User has it set to appear.
this.oTrans.SetCurrentEvent(TransactionEvent.None);
this.oTrans.Update();
When a user performs certain actions, several confirmation dialog windows may appear. For example, if a user attempts to clear a form that has unsaved changes, the user is prompted to either save these changes or clear them.
Because users can personalize each UI file, they only need to use confirmation dialog windows for the specific events they want. The ICE framework offers this functionality when you tell the derived EpiTransaction the purpose for the current event.
You do this by first calling the SetTransactionEvent and then specifying one of the TransactionEvent enumeration values. The framework evaluates the current confirmation settings for the TransactionEvent and determines if a confirmation window is necessary.
