Question

I am trying to print some paragraphs and image using Flow Document As shown in Code below

Paragraph invoiceID = new Paragraph(new Run("Invoice No : "+ txtInvoiceID.Text));
Paragraph qty001 = new Paragraph(new Run("Quantity : " + qtyText.Text));
Paragraph date001 = new Paragraph(new Run("Date : " +txtInvoiceDate.Text));

Section sec = new Section();
sec.Blocks.Add(invoiceID);
sec.Blocks.Add(qty001);
sec.Blocks.Add(date001);

FlowDocument fd = new FlowDocument();
PrintDialog pd = new PrintDialog();

fd.PageHeight = pd.PrintableAreaHeight;
fd.PageWidth = pd.PrintableAreaWidth;
fd.PagePadding = new Thickness(50);
fd.ColumnWidth = pd.PrintableAreaWidth;
fd.Blocks.Add(sec);
fd.Blocks.Add(new BlockUIContainer(barCodeImage));

IDocumentPaginatorSource dps = fd;
pd.PrintDocument(dps.DocumentPaginator,"Desciption");

I know image is locked by the process but how i can unlock this image ??

Any help please

Thanks

In WPF every control can have one parent only, since you already defined barCodeImage in xaml, it is child of some container. so you can either remove it from the container or clone the image
