将RadHtmlChart文件夹导出并保存为PDF - RadHtmlChart - UI

Question

我正在使用RadHtmlChart，我想将图表保存到App_data/Export/但它无效。它导出为PDF，但无法保存到本地文件夹。

var relativePath = "~/App_Data/Export/";

RadClientExportManager1.PdfSettings.ProxyURL = ResolveUrl(relativePath);
RadClientExportManager1.PdfSettings.FileName = "test123.pdf";
