Giedrus,
Is this a parent/child sort of form where the second form is launched from inside the first?
If so you can leave your first form as Private DS, and set your second form to Default DS. When the second form is launched from inside the first form it will be running in the private DS of the parent form so it has access to all of it's data.

>Now I want to call another form which will be able to access cursor in first form. Is it possible to do without changing property DataSession to 1 (Default data session)?
