    I have a RadAsyncUpload and the function for OnClientValidationFailed is getting called with a wrong file size error even though the file is well within the size limit.


    <telerik:RadAsyncUpload runat="server" ID="fUploader" PostbackTriggers="btnSendEmail,btnSaveDraft" OnClientValidationFailed="fileUploadValidationFailed"></telerik:RadAsyncUpload>

    server side

    fUploader.TargetFolder = uploadPath
    fUploader.AllowedFileExtensions = New String() {"*.jpg", "*.png", "*.gif", "*.jpeg", "*.bmp", "*.tiff", "*.pdf", "*.gpx", "*.tcx"}
    fUploader.MaxFileSize = 2500000


    function fileUploadValidationFailed(sender, args) {
        var fileExtention = args.get_fileName().substring(args.get_fileName().lastIndexOf('.') + 1, args.get_fileName().length);
        if (args.get_fileName().lastIndexOf('.') != -1) {//this checks if the extension is correct
            if (sender.get_allowedFileExtensions().indexOf(fileExtention.toLowerCase()) == -1) {
                alert("File type selected is not allowed.  Valid file types are .jpg, .png, .gif, .jpeg, .bmp, .tiff, .pdf, .gpx, .tcx");
            else {
                alert("File too large.  Max file size 2 MB.");
        else {
            alert("File type selected is not allowed.  Valid file types are .jpg, .png, .gif, .jpeg, .bmp, .tiff, .pdf, .gpx, .tcx");
