VisualExportTool Class

Contains methods that work in the same manner as the export commands.

Namespace: DevExpress.XtraPrinting

Assembly: DevExpress.XtraPrinting.v25.1.dll

NuGet Package: DevExpress.Win.Printing

Declaration

C#

public class VisualExportTool

VB.NET

Public Class VisualExportTool

Remarks

The VisualExportTool class allows you to invoke the Export Options dialog so that the user can specify export options, and export a document to the specified format using the specified options.

Example - Specify Export Options and Export to PDF

The following code invokes the PDF Export Options dialog with the Author field already filled in, prompts the user for the file location, exports the report to PDF, saves the PDF file, and asks the user whether to open the file with the default application.

C#

var report = new XtraReport1();
report.CreateDocument();
var pdfExportOptions = new PdfExportOptions();
// Specify export options before a dialog is displayed. 
pdfExportOptions.DocumentOptions.Author = "VisualExportTool";
VisualExportTool.ExportFile(pdfExportOptions, report.PrintingSystem);

VB.NET

Dim report = New XtraReport1()
report.CreateDocument()
Dim pdfExportOptions = New PdfExportOptions()
' Specify export options before a dialog is displayed. 
pdfExportOptions.DocumentOptions.Author = "VisualExportTool"
VisualExportTool.ExportFile(pdfExportOptions, printControl.PrintingSystem)

Example - Modify the Built-In Export to PDF Command

Use the VisualExportTool class to implement export commands that work in the same manner as built-in export commands and performs additional actions before or after the export.

The following code modifies the Export to PDF command, specifies the Author document option before the PDF Export Options dialog is invoked, and allows you to create a log entry after the export.
