            <script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/pdf.js/2.2.2/pdf.js"></script>
            <script type="text/javascript">
                window.pdfjsLib.GlobalWorkerOptions.workerSrc = 'https://cdnjs.cloudflare.com/ajax/libs/pdf.js/2.2.2/pdf.worker.js';
            </script>
            <div id="main">
                <input type="text" placeholder="Type your name" value="John" />
                <input type="text" placeholder="Type your comment" value="Smith" />
                <telerik:RadPushButton OnClientClicked="exportPDF" runat="server" Text="Export page to PDF" ID="Export1" AutoPostBack="false"></telerik:RadPushButton>
            </div>
            <telerik:RadClientExportManager runat="server" ID="RadClientExportManager1" OnClientPdfExporting="OnClientPdfExporting">
            </telerik:RadClientExportManager>
            <telerik:RadPdfViewer runat="server" ID="RadPdfViewer1" Height="550px" Width="100%" Scale="0.9">
                
            </telerik:RadPdfViewer>
            <script>
                var $ = $telerik.$;
                function exportPDF() {
                    $find('<%=RadClientExportManager1.ClientID%>').exportPDF($("#main"));
                }
                function OnClientPdfExporting(sender, args) {
                    var data = args.get_dataURI().split(',')[1];
                    setData(data);
                    args.set_cancel(true);
                }
                function setData(data) {
                    var RadPdfViewerObject = $find("<%=RadPdfViewer1.ClientID %>");
                    RadPdfViewerObject.get_kendoWidget().options.messages.defaultFileName = "Put here the desired download file name";
                    RadPdfViewerObject.fromFile({ data: data });
                    setTimeout(function () {
                        RadPdfViewerObject.get_kendoWidget().execute({ command: "DownloadCommand" });
                    }, 1000);
                    return false;
                }
            </script>
