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")).

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;
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:
static MainWindow()
{
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)
{
MethodInfo setMethod = menuPropertyInfo.GetSetMethod(true);
if (setMethod != null)
{
Application.Current.Dispatcher.BeginInvoke(new Action(() =>
{
setMethod.Invoke(radMenuItem, new object[] { radContextMenu });
}), System.Windows.Threading.DispatcherPriority.Background);
}
}
}
}
RichTextBox: Bullet list with several levels is not viewed correctly in WordPad.
In Word, this works as expected. When the document is imported into RadRichTextBox, this works as well.
The RichTextBox internal logic that imports .docx documents (DocxFormatProvider) doesn't support elements that don't need direct content, but have both start and end tags. Instead such elements should use self-closing tags.
For example, instead of <w:vertAlign w:val="baseline"></w:vertAlign> it should be <w:vertAlign w:val="baseline"/>
When such element is read during import, issues may occur. Two main known issues here are with the w:vertAlign and Relationship tags.
Using
<w:vertAlign w:val="baseline"></w:vertAlign> instead of
<w:vertAlign w:val="baseline"/> throws NullReferenceException with the following stack trace:

To work this around, import the document with the WordsProcessing library. If you need to display it in RadRichTextBox, you can export it again using the WordsProcessing library. This will normalize the tags. Then import it again using the RadDocument's DocxFormatProvider.
var dplDocxFormatProvider = new Telerik.Windows.Documents.Flow.FormatProviders.Docx.DocxFormatProvider();
RadFlowDocument flowDocument = dplDocxFormatProvider.Import(File.ReadAllBytes("../../../test.docx"), null);
var docBytes = dplDocxFormatProvider.Export(flowDocument, null);
File.WriteAllBytes("../../../modified-doc.docx", docBytes);
var rtbDocxFormatProvider= new Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.DocxFormatProvider();
RadDocument document = rtbDocxFormatProvider.Import(File.ReadAllBytes("../../../modified-doc.docx"));
Bold/Italic does not work for some font styles.
This might be a framework limitation in WPF: https://www.telerik.com/forums/some-fonts-are-not-able-to-bold-italic

Can be reproduced in the demo:
In our processes, it is very important to know if a change happened before or after another action. If all the revisions have zero seconds, it's impossible to determine the order of the changes when they happened in the same minute.
This is not a new bug introduce in SP2: it was there in SP1.
Document exported to DOCX with 2025 Q2 cannot be opened by 2025 Q1 or previous versions.
Workaround: Use document processing to fix the document.
var processing_provider = new Telerik.Windows.Documents.Flow.FormatProviders.Docx.DocxFormatProvider();
var document = processing_provider.Import(File.ReadAllBytes("C:\\Users\\test\\Downloads\\word1.docx"),null);
var bytes_ = processing_provider.Export(document, null);
var rtb_provider = new Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.DocxFormatProvider();
var doc = rtb_provider.Import(bytes_);
radRichTextBox.Document = doc;
Type in Japanese text in RichTextBox that word wraps beyond the first line and export it to PDF. The text should always be left aligned (as visually shown when typing) but has an "indent" when exported when the font is Segoe UI.
