>Can i make a subset of the record in the dataset? Like if the record in the dataset content a field that is maked true or false and I want just the true marked into another dataset.

If you are just doing a parent/child form, you can pass a datarow instead of a dataset if you just want one record to show on your child form. Does this help?

And yes, you can make a subset, I just don't know the syntax off the top of my head.
