How to batch print PDF in WPF PDFViewer control?
2 mins read
You can batch print the multiple PDF files using WPF PdfViewer by loading and printing the PDFs one by one in a loop. Add the PDFs present in a directory to a ListView and batch print the multiple PDFs that are selected from the ListView. Refer to the following code sample.
C#
char[] charSplitter = new char[] { '/' }; //Get the PDF files from the directory files = Directory.GetFiles("../../Data/", "*.pdf"); foreach (string file in files) { //Splitting the file name from the file path string[] fileName = file.Split(charSplitter); //Adding the file into the list view list.Items.Add(fileName[3]); } if (list.SelectedItems.Count > 0) { for (int i = 0; i < list.SelectedItems.Count; i++) { string fileName = list.SelectedItems[i].ToString(); for (int j = 0; j < files.Length; j++) { if (files[j].Contains(fileName)) { //Initialize the PdfLoadedDocument ldoc = new PdfLoadedDocument(files[j]); //Load the PdfDocument into PdfViewerControl/PdfDocumentView pdfViewer.Load(ldoc); //Silent print the PDF document pdfViewer.Print(); //Unload the PdfViewerControl after printing pdfViewer.Unload(); //Close the PdfLoadedDocument ldoc.Close(true); } } } }
