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 default calculation mode for a Workbook is Manual. This mode implies that the Spreadsheet does not recalculate formulas before it generates a PDF document. Call the Workbook.Calculate or Workbook.CalculateFull method to calculate all formulas in the workbook before you export it to PDF.
The following code snippet asynchronously loads the specified XLSX document and exports its first worksheet as a PDF file with the specified settings:
private async void ExportToPdf(object sender, RoutedEventArgs e) {
PdfExportOptions options = new PdfExportOptions();
options.DocumentOptions.Author = "John Doe";
options.DocumentOptions.Title = "Breakeven Analysis";
options.ImageQuality = PdfJpegImageQuality.Medium;
options.ExportBookmarks = false;
using (Workbook workbook = new Workbook()) {
try {
await workbook.LoadDocumentAsync("BreakevenAnalysis.xlsx");
await workbook.ExportToPdfAsync("Exported_Document.pdf", options, workbook.Worksheets[0].Name);
}
catch (OperationCanceledException) {
// Your code to handle cancellation
}
}
}
Private Async Sub ExportToPdf(ByVal sender As Object, ByVal e As RoutedEventArgs)
Dim options As New PdfExportOptions()
options.DocumentOptions.Author = "John Doe"
options.DocumentOptions.Title = "Breakeven Analysis"
options.ImageQuality = PdfJpegImageQuality.Medium
options.ExportBookmarks = False
Using workbook As New Workbook()
Try
Await workbook.LoadDocumentAsync("BreakevenAnalysis.xlsx")
Await workbook.ExportToPdfAsync("Exported_Document.pdf", options, workbook.Worksheets(0).Name)
Catch ex As OperationCanceledException
' Your code to handle cancellation
End Try
End Using
End Sub
