InfoPath Dev

My form has screen to enter data.

Which has two buttons previous and next.  Whenever user clicks on previous button, it should load already saved form into current screen.  Is it possible?

What you're proposing sounds impossible to me, at least without code.

As an alternative, you could:

1. Query to get a list of the xmls stored in the form library. 

2. Sort them.

3. Add a link in your form that will open the previous one

4. Add a link in your form that will open the "next" one.

Of course, these are links, that open a new xml in a new InfoPath window.

But even these steps are not easy.

If you have your forms stored in a form library, it should be easy enough for users to click on the document they wish to open, correct?

 new window it is possible, as you said i can have two buttons for prev and next.

But I wanted to replace current screen. 

This is what I'm thinking..but i need to try

Load xml from form library

parse xml and reassign the values in current form.

My bad is that I have  repeating sections (tables), calculations etc on current form
