    I have a page with a command button and a Rad window that has a content template that contain a user control. The user control has a little JavaScript for custom validations. Everything works fine until I try to use an Ajax manager. When I hook the toolbar button to the Rad windows on the default page everything breaks. I have attached the code for what I am trying to do, if you disable the Ajax manager on the default page my little program works great, however if you enable and configure the Ajax and everything breaks. Currently the Ajax manager is enabled, try running it as it is and then disable Ajax and you will see what I mean.  The first time you click the  tool bar button it appears that  everything is fine, however  if you click cancel and then click the tool bar again the user control is rendered partly and is garbled. Additionally none of the JavaScript on the user control works.
    This is not my entire project just a snipit there is a lot more going on and all the other Ajax works fine, I would like to use Ajax in this scenario to avoid post back on the tool bar button click that displays the rad window that has the user control to flow with therest of my project in terms of no post backs and everything else Ajaxified. Please see attached and help if you can. The data on the user control list box comes from the North wind data base Customers Company Name.  Thanks Ken G.
