Grig,

Sometimes you need to do an .EndEdit() or an .EndCurrentEdit(). If you put this code:

this.BindingContext[dsBook].EndCurrentEdit();

before you save, you should see that dsBook.HasChanges() should now be true.

Well.... i did that and it doesn't update. I have looked into UpdateCommand text, it looks ok. So it has to be something else. What?
