| ChartControl.ShowRibbonPrintPreview | Creates the print document and displays the Print Preview with the Ribbon toolbar of the document. |
To export the chart, use the appropriate ExportTo~ method (e.g., ChartControl.ExportToHtml, ChartControl.ExportToPdf, etc.)
Important
Note that, exporting to raster and vector images is implemented by the Chart and does not require any library.
The chart can be previewed, printed and exported to other formats only if the Printing library is available. Make sure you add a reference to the DevExpress.XtraPrinting.v18.2 assembly.
Also note that chart export to PDF requires the DevExpress.Pdf.Core library to be available.
Example
The following example demonstrates how to export a chart image inserted into XLS document to either a file or a stream.
using System.IO;
// ...
if (chartControl1.IsPrintingAvailable){
// Exports to an XLS file.
chartControl1.ExportToXls("Output.xls");
// Exports to a stream as XLS.
FileStream xlsStream = new FileStream("Output.xls", FileMode.Create);
chartControl1.ExportToXls(xlsStream);
// ...
xlsStream.Close();
