Here is the only custom script on the page, TelerikUpload_aspx.js:

        sheetCb = sender;
    }

    function OnClientFileSelected(sender, args) {
        var lblUploadResults = document.getElementById('MainContent_lblUploadResults');
        lblUploadResults.innerText = "";
        var lblSSISResults = document.getElementById('MainContent_lblSSISResults');
        lblSSISResults.innerText = "";
    }

    function OnClientFileUploaded(sender, args) {
        var fileInfo = args.get_fileInfo();

        $.ajax({
            type: "post",
            url: "TelerikUpload.aspx/GetSheetNames",
            data: JSON.stringify({ fileName: fileInfo.TempFileName }),

                var sheetNames = JSON.parse(result.d);
                sheetNames.sort();
                // Add sheet names to combo box (sheetCb)
                sheetCb.clearItems();
                sheetCb.trackChanges();
                var cbItems = sheetCb.get_items();
                for (var sheetNameIx in sheetNames) {

Hi Matt,

I've looked into the source code of Telerik controls and I was unable to find any function called "_doInitialize". With that said, I believe this error message comes from a different source such as from a different JavaScript library.

You can make a quick test by creating a brand new ASPX page and only place the ScriptManager and the AsyncUpload controls and test this page. This page shall not throw the same exception.

Kind regards,
Attila Antal
