RadPdfViewer for WPF showing blank document on windows 7

[Onkar]

 I am using window 7 version 6.1 

 I am using 2018.1.220.45 version of telerik.

XAML code :

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

     <Grid.Resources>
            <fixed:PdfDocumentSourceValueConverter x:Key="PdfDocumentSourceValueConverter" />
        </Grid.Resources>

         <telerik:RadPdfViewer  DocumentSource="{Binding DocumentSource, Converter={StaticResource                          PdfDocumentSourceValueConverter},ConverterParameter=ReadOnDemand}" />

Just given the binding for document source and showing it on a new window.

The document remains blank. No exception.

It's working fine on windows 10. 

I have also tried the telerik demo application but didn't worked.

Hello Onkar,

Currently we are unaware of such an issue. I would like to collect some more information about the problem.

Does it happen with specific document or with any? If this happens with specific one, please share the document so I could debug it locally.

Is this reproducible on a single machine or it does happen on other Windows 7 machines as well?

Did you try running the application and loading the document with the latest version of our controls?

Could you try changing the ConverterParameter to ReadAllAtOnce and share the result?

 I have tried different PDF documents and  converter parameter as 'ReadAllAtOnce' still didn't worked.

 Tried on different systems as well with same telerik 2018.1.220.45 licensed version.

Hi Onkar,

I tried reproducing the issue on Windows 7 machine with the same DLLs version you are using as well as the latest one. However I am able to properly load a pdf document in the RadPdfViewer control. I would suggest you to try updating to the latest version of our controls and see whether the issue still persists. You could also check whether there is some sort of difference in the regional format settings between Windows 7 and Windows 10 machines that you have tested the scenario on. In order to provide you with a possible solution I would need clear steps on how to reproduce the issue.
