       <script type="text/javascript">
           $(function () {
               $("#Button1").click(exportImage);
           });
           function getChart() { return $("#<%=C1CandlestickChart1.ClientID%>"); }
    
           // Export function
           function exportImage() {
               var fileName ="ExportImage";
               var type = "Png";
