Master/Content RadAjaxManager - IE Error

[Justin]

JavaScript on Content Page:

function onRequestStart(sender, args) {
    currentLoadingPanel = $find("<%= RadAjaxLoadingPanel1.ClientID %>");
    currentUpdatedControl = "<%= rightPanel.ClientID %>";
    //show the loading panel over the updated control
    currentLoadingPanel.show(currentUpdatedControl);
}

function onResponseEnd() {
    //hide the loading panel and clean up the global variables
    if (currentLoadingPanel != null)
        currentLoadingPanel.hide(currentUpdatedControl);
    currentUpdatedControl = null;
    currentLoadingPanel = null;
}

function InitiateAsyncResults(argument) {
    var m = $find("<%=RadAjaxManager.GetCurrent(Page).ClientID %>");
    m.ajaxRequest(argument);
    return false;
}

Page Load on Content Page

RadAjaxManager manager = RadAjaxManager.GetCurrent(Page);
manager.AjaxSettings.AddAjaxSetting(manager, rightPanel);
manager.ClientEvents.OnRequestStart = "onRequestStart";
manager.ClientEvents.OnResponseEnd = "onResponseEnd";
manager.AjaxRequest += new RadAjaxControl.AjaxRequestDelegate(manager_AjaxRequest);

Working great in Firefox, but is throwing an error in IE (error below).  I've added alerts into the JavaScript, to make sure it's finding the RadAjaxManager and the other controls and it is.  Again it's working fine in Firefox.

Any help or ideas would be greatly appreciated.

Hello Justin,

I made a sample site using the provided code. Here the RadAjaxLoadingPanel1 is properly shown when performing ajax requests. Also I do not see any error in IE.

Could you give us more details on your project? Or if this is not possible in public, you can open a formal support ticket and send us your project that we can debug locally and see why you get the mentioned error.

Best wishes,
Vasil
