having a lookup form in asp?
<p>OK.  Normal winform thing that I do all the time but now in asp.net.  You have a browse button on Form A and you open a new form B. For example you have user click on a browse button to select list of friends.  User clicks on the button, picks one or more friends and then presses select.  you then add them to the original forms grid.</p>

<p>Same idea using asp.net ( 2010 version using windows 7 IE browser). How do I do it? 
I have a button.  User clicks on the button a new web page opens. User selects what she wants and then presses select.  There is where i am stuck.  I would like to call a delegate in the original form which displayed the popup so that it knows which session variable to use to get the data.  How do I do this?</p>
