The performance of loading the thumbnails is decreased with the removing of the cache in PdfViewer. Possible reason is that the pages are no longer loaded asynchronously. Steps to reproduce: - Open the SDK with the thumbnails for PDFViewer. - Notice that the load of the thumbnails is slow.
The custom list styles from a document exported by RadRichTextBox's HtmlFormatProvider are not imported.
When trying to show the RadRichTextBox' LineNumberingDialog, nothing is displayed. This happens when using the NoXaml Telerik dlls and themes other than Windows11. The dialog is shown only in the Windows11 theme.
To work this around, add the following two lines in the App.xaml resources.

This is a regressiion issue in the 2024.3.924 release of Telerik UI for WPF.
Save and load of the saved XML should result of the same item IDs for every RadDiagramItem (shapes, connections).
To work this around, you can create a custom SerializationService and override its DeserializeItems method, where you can change the "makeUnique" parameter.
The issue manifests also when doing drag/drop from the RadDiagramToolBox or any other custom drag drop implementation that uses the DiagramDropInfo class (which is automatically handled by the RadDiagram's drop internal code). In this case the custom service approach won't work because the drag/drop deserialization works with a separate instance of SerializationService (SerializationService.Default) which cannot be changed. In this case, you can subscribe RadDiagram to the DragDropManaged.Drop event and manually call the SerializationService.Default.DeserializeItems method.
public class CustomSerializationService : SerializationService
{
public CustomSerializationService(IGraphInternal graph) : base(graph)
{
}
public override IEnumerable<IDiagramItem> DeserializeItems(SerializationInfo serializationInfo, bool makeUnique = false)
{
makeUnique = false;
return base.DeserializeItems(serializationInfo, makeUnique);
}
}
public MainWindow()
{
InitializeComponent();
this.diagram.ServiceLocator.Register<ISerializationService>(new CustomSerializationService(this.diagram));
DragDropManager.AddDropHandler(this.diagram, OnDiagramDrop);
}
private void OnDiagramDrop(object sender, Telerik.Windows.DragDrop.DragEventArgs e)
{
var data = DragDropPayloadManager.GetDataFromObject(e.Data, typeof(DiagramDropInfo).Name);
if (data is DiagramDropInfo)
{
SerializationService.Default.DeserializeItems(((DiagramDropInfo)data).Info, false);
}
}
A XamlParseException is raised when the theme's resource dictionaries are not merged in App.xaml. The missing resource is the RepeatButtonStyle resource.
To work this around, merge the resource dictionaries for the theme in the Resources collection of the App.xaml file.
When trying to install one of the following nuget packages an error occurs:
The same issue manifests with the NoXaml version of the same packages.
The error message is:
Severity Code Description Project File Line Suppression State Details Error Failed to add reference. The package 'Telerik.Windows.Controls.EntityFramework60.for.Wpf.Xaml' tried to add a framework reference to 'EntityFramework' which was not found in the GAC. This is possibly a bug in the package.

Hi, we use the map control in our application.
