RadPdfViewer not loading the document

[Patrick]

I am using Q1 2016 version of telerik

I have a binding for my Document source using MVVM light

This is my XAML code :

<telerik:RadPdfViewer Grid.Row="1" HorizontalAlignment="Stretch" Name="pdfViewer" VerticalAlignment="Top"
DocumentSource="{Binding DocumentPdf}" />

 

and here is my code :

public CotisationPdfVm(string url)
{
DocumentPdf = new PdfDocumentSource(new Uri(url), FormatProviderSettings.ReadOnDemand);
}

private PdfDocumentSource _documentPdf;
public PdfDocumentSource DocumentPdf
{
get { return _documentPdf; }
set
{
_documentPdf = value;
RaisePropertyChanged(() => DocumentPdf);
}

 

The url is

The document remains blank. No exception.

When I put a breakpoint in the set of my property the I have: IsStreamLoaded = false

The url is "http://109.88.185.2:60000/Reports/Cotisation/2017/CotisationReportVANDEVOORDEN Patrick-354-2017.pdf"

The uri is "http://109.88.185.2:60000/Reports/Cotisation/2017/CotisationReportVANDEVOORDEN%20Patrick-354-2017.pdf"

When I try with a browser (IE) with the same uri I can read the document.

Hi Patrick,

The reason it's not working is because of the FormatProviderSettings.ReadOnDemand setting. If you change your constructor to the following, it will work as expected:

public CotisationPdfVm(string url)
{
    DocumentPdf = new PdfDocumentSource(new Uri(url));
}

I'm forwarding this to the PdfViewer team take a look and see if this is the expected behavior when using data binding. 


Side-note:

In case you weren't aware of it, we also have a converter that lets you bind directly to the Uri and set the FormatProviderSettings via the parameter.

Here's the namespace and Resource declaration:

<!-- NAMESPACE -->
xmlns:fixed="clr-namespace:Telerik.Windows.Documents.Fixed;assembly=Telerik.Windows.Controls.FixedDocumentViewers"

<!-- CONVERTER -->
<Window.Resources>
  <fixed:PdfDocumentSourceValueConverter x:Key="DocumentSourceConverter"/>
</Window.Resources>

<!-- USAGE -->
<telerik:RadPdfViewer DocumentSource="{Binding DocumentUri, Converter={StaticResource DocumentSourceConverter}, ConverterParameter=ReadAllAtOnce}" />

Thank you for reporting this.
