It seems that the first time a Center TextAlignment is applied to the selection, its length is cached. Because of this, when the selection content (text) changes the length is not updated, thus the text doesn't align properly. It aligns accord to the initial length of the context. The content doesn't update also if the alignment is reset.
To work this around, avoid the FlowNoWrap layout mode and use only Flow.
NullReferenceException is thrown when the document gets updated after TableRow objects were removed with the Remove method of the parent Rows collection of the Table.
The table.Rows.Remove method is not properly removing some of the rows.

To work this around, use the DeleteTableRow method of the RadDocumentEditor.
RadDocumentEditor documentEditor = new RadDocumentEditor(document); documentEditor.DeleteTableRow(row);
Implement child dialogs for Style Formatting Properties Dialog. This will allow users to modify Style's properties related to font properties, paragraph properties, tabs, numbering and borders.
The issue reproduces when track changes is enabled and new text is entered. After waiting some time and pressing the Backspace on the keyboard in order to delete a character, nothing happens. You should press the Backspace a second time in order to make the deletion work. After that you can delete the content normally.
The waiting time before pressing the Backspace is usually until the next minute of the clock comes. For example, you can write something at 14:55 and wait until 14:56. Then, press Backspace.
If you check the Output pane of Visual Studio you will see the following assertion failure message printed:

When the exported document contains a very precise indent values, these are saved using scientific notation, which is unsupported in MS Word. Opening the file in Word results in the following error: "Word experienced an error trying to open the file."
Here is an example of the troublesome setting in the body of the produced document:
<w:ind w:firstLine="6.420405952667352E-06" w:left="76.53543090820312" w:right="0" />
To work this around, you can open the exported document with the WordsProcessing library. This will give you a RadFlowDocument object which then can be exported to a file again. This will save the indent values properly in the new document.
var dplProvider = new Telerik.Windows.Documents.Flow.FormatProviders.Docx.DocxFormatProvider();
using (var inputStream = File.OpenRead("../../../originalFile.docx"))
{
Telerik.Windows.Documents.Flow.Model.RadFlowDocument flowDoc = dplProvider.Import(inputStream, TimeSpan.FromSeconds(5));
using (var outputStream = File.OpenWrite("../../../convertedFile.docx"))
{
dplProvider.Export(flowDoc, outputStream, TimeSpan.FromSeconds(5));
}
}
Or if you use the RichTextBox document model only to create documents in code (without using the RadRichTextBox control), you can replace the code with the WordsProcessing API.
