Declaration
Parameters
| Name | Type | Description |
|---|---|---|
| filePath | String | A String specifying the full path (including the file name and extension) where the PDF file will be created. |
Remarks
If a file under the specified file path exists, the new file replaces it.
To show the standard Print dialog, use the ChartControl.Print method. The dialog allows end-users to print the chart, select the printer (if required), specify the range of pages to print, the number of copies, etc.
To display the DevExpress Print Preview use one of the following methods.
| Method | Description |
|---|---|
| ChartControl.ShowPrintPreview | Creates the print document and displays the Print Preview of the document. |
| 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 the chart’s data as a PDF document either to a file or to a stream.
using System.IO;
// ...
if (chartControl1.IsPrintingAvailable){
// Exports to a PDF file.
chartControl1.ExportToPdf("Output.pdf");
// Exports to a stream as PDF.
FileStream pdfStream = new FileStream("Output.pdf", FileMode.Create);
chartControl1.ExportToPdf(pdfStream);
// ...
pdfStream.Close();
}
