Instead of waiting for a kind moderator, I jumped in and moved it... Sometimes the cranky old phart can be good for something!
Does it make sense to merge this thread with your prior thread on the same topic, or is this a "fresh start" on it?
The problem gets a bit sticky due to the underlying complexity of figuring out where your application thinks the new row ought to go in the record set it is managing. Think about the model that you're trying to implement (in terms of the document/model/view paradigm). How does that model order the document (rowset), and where does the new row being added fit within the model? Is the new row in the current view, or in a different view? If the row is in another view, does the window automagically display that new view, does it switch the model to change where the row sits (either temporarily or permanently), or does it do something different?
I know that I am asking a lot of questions, but I have to understand what you want to have any chance of giving you a correct and/or usable answer.
