Try the following scenario:

• In MS Word, create a table with text in every cell
• In the RadRichTextBox, create a new document
• Activate Review/Track Changes
• Add some empty paragraphs or some text: change tracking markup will be displayed
• Just after the inserted text, copy and paste the table from MS Word: none of the cells has change tracking markup
• If you type inside the table, the new text has markup, but the text that was pasted with the table has no markup.
• If you use the right arrow on the keyboard to exit the change tracking tag, then if you paste the table, it seems to work correctly.

The default styles are not copied when using the CreateDocumentFromSelection method.

Workaround: Manually copy the styles:

var document = radRichTextBox.Document.Selection.CreateDocumentFromSelection();
document.StyleRepository.Clear();
foreach (var item in radRichTextBox.Document.StyleRepository)
{
    var style = new StyleDefinition(item);
    document.StyleRepository.Add(style);
}

Steps to reproduce: 

• In MS Word, create a table with text in every cell
• In the RadRichTextBox, create a new document
• Activate Review/Track Changes
• Copy and paste the table from MS Word: only the first cell has change tracking markup
• Insert a paragraph after the first table and paste the table again: now, none of the cells has change tracking markup

The RTF specifications states that the header of the document should start with "\rtfN" where N is the version of the RTF. Currently, the RtfFormatProvider do not save the version, but only "\rtf". Most software handles this case, but in some cases the document cannot be read.

Introduce Navigation Pane as an enhancement to the UI of RadRichTextBox, similar to the one in MS Word (View -> Show -> Navigation pane).

Hi,

This issue was referenced all the way back in 2017 in this post for Win Forms, but it appears it was never actually resolved; only a workaround was provided. I don't think this workaround will work for me, however, because I am binding to the RtfDataProvider in xaml and therefore it makes the changes to the document string before I am able to do a manual replacement of "rtf1" where it only had "rtf" for the version tag before. While changing the tag after the fact will fix the issue of it not being recognized in the other software we use, it still causes bloat because of the fact that it most cases it over triples the amount of raw text in the returned string when the textbox does not properly apply the rtf version tag.

Below is an example of the greatly enlarged amount of data before and after this error occurs:

If there is a way that I can use the workaround in that post to prevent this bloating of the data while still using my current setup with bindings, I would be happy to do so, but as it is I don't think that's the case. It seems like this is clearly a bug and something that should have a real fix on the control and not a workaround after all this time, but if that's not the case and it was left as is for a reason, I'd be happy to hear that reason.

Thanks in advance for the help.

The pasted content is not formatted properly, resulting in an InvalidOperationException("'Token EndElement in state EndRootElement would result in an invalid XML document. Make sure that the ConformanceLevel setting is set to ConformanceLevel.Fragment or ConformanceLevel.Auto if you want to write an XML fragment. ') when saving the content to DOCX.

Steps to reproduce:

• Create a document
• Activate Review/Change Tracking
• Create a table in a separate MS Word file and add some text at least in the first cell
• Copy from MS Word and paste it as the first element in the document
• Save the document as an MS Word document
  

Workaround: intercept the table paste and add an empty paragraph as the first element of the document before the table.

Another case:

• Create a new document
• Be sure that Change Tracking is deactivated
• Create a table in a separate MS Word file and add some text at least in the first cell
• Copy from MS Word and paste it as the first element in the document
• Activate Review/Change Tracking
• Just after the first table, paste the table again: the second table seems to be merged with the first table, with no paragraph in between, but with the vertical line in the margin showing that the second table has change tracking
• Save the document as a MS Word document
