I'm using RadHtmlChart and I want to save the chart to App_data/Export/
But it is not working. It exports to PDF, but it's not able to save to a local folder.
var relativePath = "~/App_Data/Export/";
RadClientExportManager1.PdfSettings.ProxyURL = ResolveUrl(relativePath);
RadClientExportManager1.PdfSettings.FileName = "test123.pdf";
