+                    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);
