With the R1'19 Service Pack release of Telerik UI for Xamarin, we've added a few new features to our PDF Viewer, Visual Studio 2019 Preview 3 support and a variety of improvements across the suite.

With the first major release of the year of Telerik UI for Xamarin, we released the PdfViewer - a component to display PDF documents right within your app. With the service pack release, we built on top of it and have included some more nifty features:

  • FileDocumentSource - you can now point RadPdfViewer to a file on your device. Moreover, it is smart enough to allow you to provide it through a string:
    <telerikPdfViewer:RadPdfViewer x:Name="pdfViewer"  Source="{Binding FilePath}" />
    Where FilePath is a string property in your viewmodel:
    string FilePath {get;}
  • RadPdfViewer.Document property is now public, so you can easily track when the document is loaded/changed
  • When a new document is loaded, it is automatically adjusted to fit the current width for best viewing experience
  • ByteArrayDocumentSource.IsImportAsync is now true by default and available for configuration

VisualStudio 2019 Preview 3

I have good news for all of tech enthusiasts already on VisualStudio 2019 – Telerik UI for Xamarin is compatible with the latest version of VisualStudio 2019 (Preview 3). You can take advantage of the convenient project template which creates a project ready to accommodate all Telerik controls...

... or any of the ItemTemplates that allow you head start in complex screen creation.

Of course, all the controls are available and ready to use in the Telerik UI for Xamarin Toolbox in your Visual Studio 2019.

  • DaysOfMonth collection is cleared when changing the repeat rule
