ASP.Net Web forms

[Vannela]

Can we have MDI web forms concept in ASP.Net ?
May not exactly how it works in win forms but the concept
should be same?

In the Parent window we should be able to refer any of the
child window , we can aslo cascade the child forms on the
parent window is this possible?
If so can u give brief explanation, or the sites or books
where i can get this things.

Thank you.
