The document will be imported with a loss of content. The reason is that ASCII85Decoder will throw an ArgumentException when the stream doesn't end with '~>'. Although this is invalid case according to PDF specification, other applications are handling it and the document is successfully visualized in them. We may also consider implementing workaround that handles such invalid streams.

Currently, if you have a cell that merges into multiple columns, when you click on the column header, this will select also the adjacent columns where the merged cell extends. Add an option to disable this functionality and select only the cells in the clicked column.

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.

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;

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;
}
