When the FixedDocumentSinglePagePresenter content control is used to visualize PDF files in custom PDF viewer implementation a raise condition can be occurred leading to NullReferenceException with the following stack trace:
at Telerik.Windows.Documents.Fixed.UI.UIElementsHelper.FillPageContentElementsInPanel(Canvas container, RadFixedPage page)
at Telerik.Windows.Documents.UI.FixedDocumentSinglePagePresenter.CreateContent(RadFixedPage page)
at Telerik.Windows.Documents.UI.FixedDocumentSinglePagePresenter.PageLoader_WorkCompleted(Object sender, WorkCompletedEventArgs e)

at System.Windows.Threading.ExceptionWrapper.InternalRealCall(Delegate callback, Object args, Int32 numArgs)
at System.Windows.Threading.ExceptionWrapper.TryCatchWhen(Object source, Delegate callback, Object args, Int32 numArgs, Delegate catchHandler)

The exception is thrown since the current page is unloaded while the content is being parsed.

I want to draw the signature box, like in Adobe Acrobat Reader.

This is very important when the document needs more than 1 signature.

  • Create new WPFApplication.
  • Add a RadPdfViewer to the main window
<Window x:Class="YourProject.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:local="clr-namespace:MaquetteTelerikPDFViewer"
        mc:Ignorable="d"
        xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"      
        Title="MainWindow" Height="450" Width="800">
    <Grid>
        <telerik:RadPdfViewer x:Name="pdfViewer"/> 
    </Grid>
</Window>
  • Open the pdf file
    public partial class MainWindow: Window
    {
        public MainWindow()
        {
            InitializeComponent();
        }

        protected override void OnInitialized(EventArgs e)
        {
            base.OnInitialized(e);
            using(Stream stream = new FileStream(@"radExport.pdf",FileMode.Open,FileAccess.Read)){
                pdfViewer.Document = new PdfFormatProvider(stream).Import();
            }
        }
    }

The exception is thrown with the message "Password is not correct" even when the user password is correct. This issue occurs for specific encryption algorithm parameters only.

Item is declined because this functionality is not supported and has a logged feature request to support it.

I have a pdfviewer bound to a richtextbox like in your samples. But I want to keep the wpf viewer in fit to window scaling mode while changing the content of the richtextbox.

Right now the pdfviewer will rescale to 100 % on each update.
