I recently posted a quick fix for CoolGridView control. Below is a list of fixes.

1. It now works correctly in Internet Explorer 6.0 and 7.0.
2. Fixed the alignment of the fixed headers and footers when there are other HTML element or server controls before the CoolGridView in a page.
3. Control's scroll bars are properly rendered in the browser or in a modal window after a postback, or after a callback using AJAX control toolkit UpdatePanel.

Download the updated CoolControls and sample web application project from here.

For those who are using the CoolGridView control inside AJAX control toolkit's UpdatePanel control, make sure you have the following javascript code at the bottom portion of your ASPX page.

//This javascript code is required if you are using a CoolGridView inside an update panel.

function AjaxEndRequestHandler(sender, args) {
   var p = sender._updatePanelClientIDs;
   if (p != null)
   for (var j = 0; j < p.length; j++) {
          var scripts = $get(p[j]).getElementsByTagName("script");
          // .text is necessary for IE.
          for (var i = 0; i < scripts.length; i++) {
              try {
                   eval(scripts[i].innerHTML || scripts[i].text);
              } catch (e2) { }
          }
    }
}

try {
Sys.WebForms.PageRequestManager.getInstance() .add_endRequest(AjaxEndRequestHandler);
}
catch (e) { }

You can place this code in your master page if you wish. Please look at the sample web application included in the ZIP file.
