title: Passing information between windows ASP.net
body: <p>Here is the problem: I have a HTML page called test.html and an ASPX page called getitem.aspx.</p>
  
  <p>Now what I want to do is, upon clicking a button on test.html, I want the getitem.aspx page to open in a new dialog and allow entry on a text box. After clicking the OK button on getitem.aspx, this dialog should close and the entry should be passed back to the html page.</p>
  
  <p>The issue is that the getitem.aspx has several buttons that trigger postback - but I only want the item from the text box to be sent back to test.html upon clicking of the OK button and not any other buttons.</p>
  
  <p>How could I implement this?</p>
