RadAjaxManager won't update radgrid

I have a radgrid which should update when a checkboxlist is changed(achieved on a on selected event which is triggered by AutoPostBack) however when I check a checkbox in the list the RadAjaxLoading picture will work correctly to display the loading image over where the RadGrid is however it will never go away and re-display the grid. According to console errors in my web browser, I keep getting a error of:

Uncaught TypeError: Object [object Object] has no method '_destroyTree'

This is how i've set up my manager if it helps at all:

<telerik:RadAjaxManager ID="RadAjaxManagerNotesView" runat="server">
    <AjaxSettings>
        <telerik:AjaxSetting AjaxControlID="RadGridNotes">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="RadGridNotes" LoadingPanelID="RadAjaxLoadingPanel" />
            </UpdatedControls>
        </telerik:AjaxSetting>
        <telerik:AjaxSetting AjaxControlID="CheckBoxListCategories">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="RadGridNotes" 
                    LoadingPanelID="RadAjaxLoadingPanel" />
            </UpdatedControls>
        </telerik:AjaxSetting>
    </AjaxSettings>
</telerik:RadAjaxManager>

Can anybody help me solve this error? The RadGrid will never be re-displayed as of current

This script solved my problem:

function _destroyTree2(element) {
    if (element.nodeType === 1) {
        var childNodes = element.childNodes;
        for (var i = childNodes.length - 1; i >= 0; i--) {
            var node = childNodes[i];
            if (node.nodeType === 1) {
                if (node.dispose && typeof (node.dispose) === "function") {
                    node.dispose();
                }
                else if (node.control && typeof (node.control.dispose) === "function") {
                    node.control.dispose();
                }
                var behaviors = Sys.UI.Behavior.getBehaviors(node);
                for (var j = behaviors.length - 1; j >= 0; j--) {
                    behaviors[j].dispose();
                }
                this._destroyTree(node);
            }
        }
    }
}

Sys.WebForms.PageRequestManager.getInstance()._destroyTree = _destroyTree2

Put it on the end of the page.

Found the error to be an incompatibility with .NET 4.0 and an old version of telerik(2009) managed to get around the error by using the following patch in a separate JavaScript file and including it in the footer of my master page.
