Hi

Thanks for replying. Here are the answers:

1. The querystring was created dynamically and then I used the hyperlink
control to open the aspx page from InfoPath.

2. Yes, I think you are right but I can not put the InfoPath form (hosted in
SharePoint) in a xmlformview control because the InfoPath xsn is a template
published in a forms library. Every time a user clicks the new button in the
forms library, a new form opens, user enters data and a xml is saved in the
forms library. If I use xmlformview to host this infopath template then i
will have to manage the "New" button functionality.

I hope I was able to clarify things in an efficient manner. I know these
technical questions are sometimes difficult to understand, especially, for
the developers who are not working on that issue. In simpler words, I am
looking to create a pop up form, just like the ones we use in our asp.net
applications where we open a popup form, do some processing and send the data
back to the original aspx page. In asp.net we have sessions. we can simply
store the data in a session and later retrieve it from the session again but
in this case, there is no way to manage the session. the session is managed
between the aspx page (host) and the infopath (xmlformview control) but there
is no management of session between the aspx page and the infpath form hosted
in sharePoint. that's where there is a problem. Any ideas on how we can
manage session between an infopath form hosted in sharepoint and an external
aspx page hosted on the same sharepoint server??

Thanks
