TreeListView with IsReadOnly True and EnableColumnVirtualization True.
Custom column is defined in code with IsReadOnly False.
Runtime, user edits a cell from the column and then scrolls horizontally - this leads to UI freeze, endlessly.

Currently, the appointments in the same group in TimelineViewDefinition will be drawn on multiple lines if their date ranges overlap. Internally, the group height is split into "rows" for each overlapping that happens and then each appointment is rendered on the corresponding row.
Add a mechanism to control the number of rows and the row position of each appointments in the same group.

Currently, the GenerateExport method provides a PivotExportModel instance where the Cells collection is populated with the formatted value of the cells.
We could add an option to allow the copying of the raw data instead.

Bug Report
When the RadWatermarkTextBox control has a label set through the Label property and the dark variation of the Fluent theme is set, hovering over the control will change its visual state and background to white, however, the label will still remain white (default foreground for the dark variation), thus appearing as if it has disappeared.

RichTextBox
Type:
Feature Request
FormatException is thrown during the import of a table coming from a docx document when the application culture is "sv-SE". This happens when the column width in the document is a floating point number (ex: 120.65). The Swedish culture uses "," as decimal separator and " " as the number group separator, which makes any invariant decimal value (like 120.65) invalid during standard parsing (ex: float.Parse("120.65")).
Stacktrace:
FormatException: The input string '4514.5' was not in the correct format. at System.Single.Parse(String s) Telerik.Windows.Controls.RichTextBox.dll!Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.Import.TableImporter.ImportTableGrid(Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.Parsing.Style style) Telerik.Windows.Controls.RichTextBox.dll!Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.Import.TableImporter.Import(Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.Parsing.Style parentStyle) Telerik.Windows.Controls.RichTextBox.dll!Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.Import.MainDocumentImporter.BuildTable(Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.Parsing.Style parentStyle) Telerik.Windows.Controls.RichTextBox.dll!Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.Import.MainDocumentImporter.BuildBody() Telerik.Windows.Controls.RichTextBox.dll!Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.Import.MainDocumentImporter.BuildDocument() Telerik.Windows.Controls.RichTextBox.dll!Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.Import.MainDocumentImporter.Import()Telerik.Windows.Controls.RichTextBox.dll!Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.Import.DocxImporter.ReadXmlContentFromPackage(Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.Import.DocxPartImporterBase importer) Telerik.Windows.Controls.RichTextBox.dll!Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.Import.DocxImporter.ReadXmlContentAndRelationsFromPackage(Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.Import.DocxPartImporterBase importer) Telerik.Windows.Controls.RichTextBox.dll!Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.Import.DocxImporter.Import() Telerik.Windows.Controls.RichTextBox.dll!Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.DocxFormatProvider.Import(System.IO.Stream input)
To work this around, switch to InvariantCulture during the import and return the original culture after that.
var cultureCache = Thread.CurrentThread.CurrentCulture;
Thread.CurrentThread.CurrentCulture = System.Globalization.CultureInfo.InvariantCulture;
Thread.CurrentThread.CurrentUICulture = System.Globalization.CultureInfo.InvariantCulture;
var provider= new DocxFormatProvider();
rtb.Document = provider.Import(stream);
Thread.CurrentThread.CurrentCulture = cultureCache;
Thread.CurrentThread.CurrentUICulture = cultureCache;

Bug Report
The fill selection stops working, after a filtering is applied and the currently selected cell is filtered out (it gets hidden). This prevents from displaying the fill selection cross displayed when you hover the bottom right corner of a selected cell. Any further changes in the selection doesn't re-enable the selection fill feature.
To work this around, you can set the IsEnabled property of the FillSelection on selection changed.
private RadWorksheetEditor activeWorksheetEditor;
public MainWindow()
{
InitializeComponent();
this.spreadsheet.ActiveSheetEditorChanged += (s, e) =>
{
if (activeWorksheetEditor != null)
{
activeWorksheetEditor.Selection.SelectionChanged -= Selection_SelectionChanged;
}
activeWorksheetEditor = this.spreadsheet.ActiveWorksheetEditor;
activeWorksheetEditor.Selection.SelectionChanged += Selection_SelectionChanged;
};
}
private void Selection_SelectionChanged(object? sender, EventArgs e)
{
this.spreadsheet.ActiveWorksheetEditor.Selection.FillSelection.IsEnabled = true;
}

Working with the RadContextMenu that comes from the RadRichTextBoxUI, when having analytics enabled, produces a NullReferenceException.
Manually set the Menu property on the PreviewMouseLeftButtonUp event of the RadMenuItem:

EventManager.RegisterClassHandler(typeof(RadMenuItem), PreviewMouseLeftButtonUpEvent, new MouseButtonEventHandler(OnRadMenuItemPreviewMouseLeftButtonUp), true);
}
private static void OnRadMenuItemPreviewMouseLeftButtonUp(object sender, MouseButtonEventArgs e)

RadMenuItem radMenuItem = (RadMenuItem)sender;
RadContextMenu radContextMenu = radMenuItem.ParentOfType<RadContextMenu>();
if (radContextMenu != null)
{
PropertyInfo menuPropertyInfo = radMenuItem.GetType().GetProperty("Menu", BindingFlags.Public | BindingFlags.Instance);
if (menuPropertyInfo != null)

{
setMethod.Invoke(radMenuItem, new object[] { radContextMenu });
