To improve performance on our web site, we only add RADTooltip instances to our control hierarchy (ASP.NET) when a user is logged in. We do have RADEditor instances but these have "Enabled" set to false.

This works great - no Telerik script files are downloaded until we need them.

Unfortunately, when a postback occurs, a "scriptStartupBlock" is being emitted and causing a JavaScript error, since none of the Telerik client libraries have been downloaded. Here is the script:

if (!$telerik.isSafari)
{
var links = document.body.getElementsByTagName('link');
if (links && links.length>0)
{
  var documentHead = document.getElementsByTagName('head')[0];
  if (documentHead)
  {
   for (var i=links.length-1;i>=0;i--)
   {
    var linkTag = links[i];
    if (linkTag.title == 'Telerik stylesheet')
    {
     if ($telerik.isIE)
     {
      linkTag = linkTag.cloneNode(true);
     }
     documentHead.appendChild(linkTag);
    }
   }
  }
}
}
