Remarks

Important

The RichEditDocumentServerExtensions class is defined in the DevExpress.Docs.v24.2.dll assembly. Add this assembly to your project to use the RichEditDocumentServerExtensions members. You need a license for the DevExpress Office File API Subscription or DevExpress Universal Subscription to use this library in production code.

For information on PDF Export features and limitations, refer to the following help topic: Export to PDF.

Important

Take into account the following when you call this method:

• The events fired by this method call may occur in a different thread than the target operation.

• The operation is not thread safe (the document should not be accessed simultaneously by different threads). Wait until the operation is completed before you continue to work with the document (for example, use the await operator).

The code sample below asynchronously exports a document to the PDF format:

C#

private async void ConvertDocx2Pdf()
{
  using (RichEditDocumentServer wordProcessor = new RichEditDocumentServer())
    {
        try
        {
            await wordProcessor.LoadDocumentAsync("Document.docx");

            await wordProcessor.ExportToPdfAsync(new FileStream("Documents\\Result.pdf",
    FileMode.Create, FileAccess.ReadWrite));
        }
        catch (OperationCanceledException)
        {
            // Your code to handle cancellation
        }
    }
}

VB.NET

Private Async Sub ConvertDocx2Pdf()
  Using wordProcessor As New RichEditDocumentServer()
    Try
      Await wordProcessor.LoadDocumentAsync("Document.docx")

      Await wordProcessor.ExportToPdfAsync(New FileStream("Documents\Result.pdf", FileMode.Create, FileAccess.ReadWrite))
    Catch e1 As OperationCanceledException
      ' Your code to handle cancellation
    End Try
  End Using
End Sub
