Because asp.net only allows 1 form declaration per page I have to assume you are referring to different windows and you wish to select something in one window and have it reflect in the other.

Now the sleekest solution would be to use javascript and a application called lightbox (its a kind of window popup very clean and neat. then use javascript to do the transfer based on the selection.

The other bit more advanced option would be using a web service and javascript, when an object is chosen in form 2 it sets a Session variable , then in form 1 use a java-script Interval method to run a method in the web service that will look for that saeeion variable change. but this is far more complicated and will be overkill for a simple app.
