Which events should I use for auditing?

Which BO events should I place my auditing code into?

I'm using the AfterAddNew event to place my created by audit info in the proper fields. I believe this is the right event for new records, but I'd like confirmation. ;-)

Private Sub BluePrintsBO1_AfterAddNew(ByVal e As System.EventArgs) Handles BluePrintsBO1.AfterAddNew
Me.BluePrintsBO1.Created = Now
Me.BluePrintsBO1.CreatedBy = SystemInformation.UserName
End Sub

Which event should I use when a record is modified?

Thanks

You will want to use the Navigating event of the BO. This event is fired through the BusinessBindingSource when using grids.

Whoops! spoke too soon. I'm using a grid so I'd like to update the Modified fields when they change a row. So if they move to another row if they made any changes to that row I'd need to update those fields before they moved.

So I thought I would use the CheckRulesOnCurrentRow method in the BO.

So... my next questions are...

Is there a dirty property for each record i could check to determine whether I need to update these fields?

Am I correct in my approach here?

That'll work. I'll test the editing state on the save. ;-)

It just depends on what you are trying to accomplish and what type of events you are auditing. You are correct on the Add...this is what I would do. As for the Edit, I would do this in the BeforeSave or AfterSave event and test on the EditingState of the BO to know if this is a new or existing record.
