title: Best option for modal popup window in ASP.NET?
body: <p>This question was asked a few years ago, so I'm going to ask it again.</p>
  
  <p>I'm looking for the best/cleanest option to display a modal popup window upon the click event of an ASP Button control. The contents of the window will be an aspx page. </p>
  
  <p>Cross-browser compatibility is a requirement</p>
  
  <p>jquery/plugins aren't out of the question if they fit the mold. </p>
