RadPdfViewer stops working when Telerik.Documents.Core added

[Neil N]

This was working fine in a Xamarin Forms (UWP) project

        public void PrintReferralReport(byte[] pdf)
        {
            pdfCurrent = pdf;
            this.pdfViewer.Source = pdf;
            memberReferralPopUpVM.IsPDFGridVisible = true;

        }

<telerikPdfViewer:RadPdfViewer x:Name="pdfViewer" Grid.Row="1"/>

As soon as Telerik.Documents.Core was added to a different project (doesn't even have to be used), the viewer stopped appearing.

<PackageReference Include="Telerik.Documents.Core" Version="2022.3.1108" />

<PackageReference Include="Telerik.UI.for.Xamarin" Version="2022.3.1109.1" />

Hi Neil,

Could you please elaborate why you reference both packages in the project? Telerik UI for Xamarin NuGet has a reference to the Telerik.UI.for.Xamarin.Documents.Core package.

If you want to add the Documents.Core package as nuget to a Xamarin project, you have to use the Telerik.UI.for.Xamarin.Documents.Core, not Telerik.Documents.Core.

Here are the references I have in the .csproj file:

  <ItemGroup>
    <PackageReference Include="Telerik.UI.for.Xamarin" Version="2022.3.1109.1" />
    <PackageReference Include="Telerik.UI.for.Xamarin.Documents.Core" Version="2022.3.1108" />
    <PackageReference Include="Xamarin.Forms" Version="5.0.0.2196" />
    <PackageReference Include="Xamarin.Essentials" Version="1.7.0" />
  </ItemGroup>

The pdf document is displayed as expected.

If you manually adding the references to the project, then you should add the Core.dll.

Hi Didi,

To reiterate, as soon as Telerik.Documents.Core was added to a different project (doesn't even have to be used), the viewer stopped appearing.

The Xamarin project has no reference to Document.Core. 

<PackageReference Include="Telerik.UI.for.Xamarin" Version="2022.3.1109.1" />

is the version of Telerik UI for Xamarin we're using in the Xamarin Forms project.

 

<PackageReference Include="Telerik.Documents.Core" Version="2022.3.1108" />

is what we're using in a cross platform .NET Standard library project

Hi Neil,

I have tested the scenario. I have two different projects and there isn't a reference between them. The first project is a Xamarin.Forms blank project with PdfViewer in it. The second project is a class library project with Telerik.Documents.Core added to it. The Xamarin project works as expected and the pdf viewer displays the document.

Please explain what does different project mean? Send me both projects so I can further research the case. If you do not want to send them in the forum, open a support ticket and attach the projects to it. 

Also on which platform the behavior occurs.
