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:

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);
}
}
}
}
The TableCellProperty.Padding property of the "TableNormal" StyleDefinition doesn't take effect in the UI. The same is valid for the TableProperties.CellPadding property.
To work this around, you can manually set the Padding property of all TableCell elements in the RadDocument.
var cells = radDocument.EnumerateChildrenOfType<Telerik.Windows.Documents.Model.TableCell>();
foreach (var cell in cells)
{
cell.Padding = new Padding(10);
}
