Remarks

To display the DevExpress Print Preview, use one of the following methods:

Method	Description
HeatmapDiagramControl.ShowPrintPreview	Creates a print document and displays the Print Preview dialog.
HeatmapDiagramControl.ShowRibbonPrintPreview	Creates a print document and displays the Print Preview with the Ribbon toolbar.

To export the diagram, use one of the ExportTo~ methods (for example, call the HeatmapControl.ExportToPdf method to export the diagram to a PDF file).

Important

The diagram can be previewed, printed or exported to other formats only if the Printing library is available (except when you export to raster and vector images). Ensure you add a reference to the DevExpress.XtraPrinting.v25.2 assembly.

Note that the DevExpress.Pdf.Core library should be available to export the heatmap to PDF.
