I need to export a few (could be just one or more tha开发者_如何转开发n one) Microsoft Charts to a PDF and Excel. It needs to happen on a button click and the charts should be directly exported to a PDF without getting rendered onto a web page.
Environment used: ASP.NET
Please suggest the approach to achieve this.
cheers
Here is an example: Microsoft Chart Controls to PDF with iTextSharp and ASP.NET MVC
Here is a sample code for exporting MS chart control to Excel. Hope this helps.
string tmpChartName = "test2.jpg";
string imgPath = HttpContext.Current.Request.PhysicalApplicationPath + tmpChartName;
Chart1.SaveImage(imgPath);
string imgPath2 = Request.Url.GetLeftPart(UriPartial.Authority) + VirtualPathUtility.ToAbsolute("~/" + tmpChartName);
Response.Clear();
Response.ContentType = "application/vnd.ms-excel";
Response.AddHeader("Content-Disposition", "attachment; filename=test.xls;");
StringWriter stringWrite = new StringWriter();
HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite);
string headerTable = @"<Table><tr><td><img src='" + imgPath2 + @"' \></td></tr></Table>";
Response.Write(headerTable);
Response.Write(stringWrite.ToString());
Response.End();
