OnGridDestroying ScriptLoader is already loading scripts

[glenn]

Hi,

I attached an event on OnGridDestroying that checks if the grid has been changed and asks the user to save the changes.
But i always get the error: Microsoft JScript runtime error: Sys.InvalidOperationException: ScriptLoader.loadScripts cannot be called while the ScriptLoader is already loading scripts.

I don't get this error when i attach this handler to another event like onclick.
Somebody who knows the reason?

This error only happens in IE. firefox doesn't give this error.

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">
<script type="text/javascript">
    var hasChanges, inputs;

    function GridCreatedEventHandler(sender, eventArgs)
    {
        var gridElement = sender.get_element();
        var elementsToUse = [];
        inputs = gridElement.getElementsByTagName("input");
        for (var i = 0; i < inputs.length;i++)
        {
            if(inputs[i].type.toLowerCase() == "hidden")
            {
                continue;
            }
            Array.add(elementsToUse, inputs[i]);
            inputs[i].onchange = OnChangeEventHandler;
        }
        setTimeout(function(){if(elementsToUse[0])elementsToUse[0].focus();},100);
    }

    function GridDestroyingEventHandler(sender, eventArgs)
    {
        if(hasChanges)
        {
            if(confirm("Update changes?"))
            {
                hasChanges = false;
                var masterTable = $find("<%= grdvGrid.ClientID %>").get_masterTableView();
                masterTable.updateEditedItems();
            }
            else
            {
                hasChanges = false;
            }
        }
    }

    function OnChangeEventHandler(e)
    {
        hasChanges = true;
    }
</script>
</telerik:RadCodeBlock>


<CSystems:GridView ID="grdvGrid" runat="server">
    <ClientSettings>
        <ClientEvents OnGridCreated="GridCreatedEventHandler" OnGridDestroying="GridDestroyingEventHandler"/>
    </ClientSettings>
</CSystems:GridView>

Thx in advance,
Glenn

Hi Glenn,

Have you encountered that you experience the issue with the script loading when using RadScriptManager instead of asp ScriptManager control? If this is the case, we will appreciate if you isolate a stripped working version of your project (attached to a formal support ticket) which operates properly with the MS ScriptManager and fails with RadScriptManager. We will debug it locally and advice you further.

Also verify that you are using the latest release 2008.2.723 of RadControls for ASP.NET AJAX (announced a couple of days ago).

I've had similiar problems... The minute I removed the RadAjaxManager it solved the problem. I had to combine the standard Microsoft controls (updatepanel, etc.) with the telerik controls that im using. The problem seems to be related to working with dynamically loaded user controls.
