Some lines on attached files are to thick. Other pdf programs shows that correctly.

The numeric box that allows you to select the "to" page in the PrintPreviewControl is clipped when the "Pages:" and "to" strings are translated to a language where these words are longer. For example, this reproduces with Dutch culture which uses the "Pagina's:" and "naar" texts.

To work this around, you can get the Grid panel that hosts the content and increase the Width of one of its ColumnDefinitions.

  private void PrintPreviewControl_Loaded(object sender, RoutedEventArgs e)
  {
      var printPreview = (PrintPreviewControl)sender;
      var rootGrid = printPreview.FindChildByType<Grid>();
      rootGrid.ColumnDefinitions[0].Width = new GridLength(355);
  }

In the scenario where the Fluent theme is applied and the MonthViewDefinition'sAllowCustomAppointmentSize property is set to True, appointments with different heights may overlap the expand/collapse RadToggleButton when collapsed.

To work this around, extract the default GroupHeaderStyleSelector for the Fluent theme. Then, extract the Style with x:Key="MonthViewBottomLevelWeekGroupStyle" and modify the Padding property's value. Set this Style to the MonthViewBottomLevelWeekGroupStyle property of the extracted OrientedGroupHeaderStyleSelector (default GroupHeaderStyleSelector). Finally, set an instance of the modified style selector to the GroupHeaderStyleSelector property of RadScheduleView.

Using the SpreadStreamExport feature of RadGridView doesn't work as expected when exporting DateTime objects. It exports the dates as String values which prevents the date-related features (like formatting) to work in Excel. 

To work this around, you can create a custom SpreadStreamExportRenderer and override its SetCellValue method. This will allow you to manually provide the DateTime object instead of the string.

  public class MyRenderer : SpreadStreamExportRenderer
  {
      public override void SetCellValue(DataType dataType, object value)
      {
          DateTime date;
          if (value != null && DateTime.TryParse(value.ToString(), out date))
          {
              base.SetCellValue(DataType.DateTime, date);
              var cell = this.GetCell() as ICellExporter;
              cell.SetFormat(new SpreadCellFormat() { NumberFormat = "yyyy-MM-dd HH:mm:ss" });
              return;
          }
          base.SetCellValue(dataType, value);
      }
  }

 spreadStreamExport.RunExportAsync(FILENAME, new MyRenderer(), options);

The exception occurs when publishing .NET 9 application and the "Deployment Mode" in the "Publish profile" is set to "Self-contained".

The exception is not displayed, but instead the application crashes at startup and it seems like it cannot start at all. You can see the error in the Events Viewer tool of the Windows OS, after you navigate to the "Windows Logs-->Application" menu.

This is not reproducible in .NET 8.

The original stacktrace where this was hit is the following:

System.IO.FileNotFoundException: Could not load file or assembly 'System.Windows.Forms, Version=8.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'. The system cannot find the file specified.

   at Telerik.Windows.Controls.RadContextMenu.AttachHandler(UIElement element)
   at Telerik.Windows.Controls.RadContextMenu.CreateReferences(UIElement element)

To work this around, you can try one of the following ideas:

• Change the target framework of your project to .NET 8 or earlier.
• Use the "Framework-dependent" Deployment mode in the Publish profile.
• Add a reference to the C:\Program Files\dotnet\shared\Microsoft.WindowsDesktop.App\9.0.0\System.Windows.Forms.dll file in your project.

The UPCE values entered in the RadBarcode control when Symbology is set to UPCE are not displayed. 

To work this around use the old RadBarcodeUPCE control until this is fixed.

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.
