OK, fair enough.

Why do you need to save or create anything? Your original request said:
"Hi, I need just a temporary dataset. I don't have a table, nor business
rules. Just want a dataset which I can fill with three fields and show
in a grid. So, how do I create an empty dataset?"
Just create the data, populate the grid, show the dialog, and after
the user makes their selection, hide the dialog, grab their selection,
release the dialog, and then proceed with your app based on their
selection. No databases, no bizobjs, no saving, no connections - keep
it simple!
