How to: Export a Chart
The Chart Control requires the XtraPrinting Library to export the chart to all formats except for images. Your project should contain the DevExpress.XtraPrinting assembly reference to use the print API.
The Chart Control sends a post back request to the server to generate a file that contains the export result. You should configure the chart control on the post back request the same as on the initial page load to print the chart correctly. Otherwise, the exported chart differs from the chart on the page.
Refer to the How to export a web chart on the client side topic for an example.
