+![Pdf with Barcodes](images/pdf-with-barcodes.png)  
+
+## Solution
+
+To add a barcode to a PDF document, consider using the [WinForms BarcodeView]({%slug barcodeview-overview%}): 
+
+1\. First, [generate an image of the barcode]({%slug barcodeview-export-to-image%}).
+
+2\. Then, add the [image to the PDF document]({%slug pdf-from-images-with-radfixeddocumenteditor%}). Here is a sample code snippet:
+
+    ```csharp
+    Telerik.WinControls.UI.Barcode.QRCode qrCode1 = new Telerik.WinControls.UI.Barcode.QRCode();
+    RadBarcodeView radBarcodeView = new RadBarcodeView();
+    radBarcodeView.BindingContext = new BindingContext();
+    qrCode1.Version = 1;
+    radBarcodeView.Symbology = qrCode1;
+    radBarcodeView.Text = "radBarcodeView1";
+    radBarcodeView.Value = "1234567";
+    radBarcodeView.Invalidate();
+    System.Drawing.Image img = radBarcodeView.ExportToImage(200, 200);
+    string imageFilePath = "barcodeImage.png";
+    img.Save(imageFilePath, System.Drawing.Imaging.ImageFormat.Png);
+
+    RadFixedDocument fixedDocument = new RadFixedDocument();     
+    RadFixedDocumentEditor documentEditor = new RadFixedDocumentEditor(fixedDocument);
+    FileStream fileStream = new FileStream(imageFilePath, FileMode.Open);
+    Telerik.Windows.Documents.Fixed.Model.Resources.ImageSource _imageSource = new Telerik.Windows.Documents.Fixed.Model.Resources.ImageSource(fileStream);
+    documentEditor.InsertImageInline(_imageSource);
+    documentEditor.InsertLineBreak();
+    documentEditor.Dispose();
+    PdfFormatProvider provider = new PdfFormatProvider();
+    string outputFilePath = "output.pdf";
+    File.Delete(outputFilePath);
+    using (Stream output = File.OpenWrite(outputFilePath))
+    {
+        provider.Export(fixedDocument, output);
+    }
+    Process.Start(new ProcessStartInfo() { FileName = outputFilePath, UseShellExecute = true });
+    ```
+
+## Notes
+
+- The WinForms BarcodeView method is suitable for applications where a barcode image can be generated and saved before adding it to the PDF: [Generating a Bar Code Image outside WinForms]({%slug barcodeview-generating-image-console-app%}).
