title: Display modal after postback without ASP.NET Ajax
body: <p>I have an ASP.NET button.  When the button is clicked, I'd like a modal popup to display after the server-side code for the button runs.  I don't want to use the ASP.NET Ajax control toolkit modal popup extender.</p>
  
  <p>With ASP.NET Ajax, I can hook into the end request event.  Is there a way to do this without ASP.NET Ajax. just jQuery?  I basically want to run some javascript after the server side click code runs, after the postback.</p>
