I have an ASP.Net page which gets created using 6 user controls. There is a link on one of the controls which opens up a pop up window. The pop up window has a dual listbox and the user may select one or more items from here. Now when I post the values back to the parent window, on the parent form I lose the values which I had filled up earlier to openeing the pop up. It seems I am losing the values in the viewstate.<BR><BR>Any information on why this is happening?<BR><BR>Thanks for your help!
