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

In the Track Change mode, try to insert several images using standard InsertPictureCommand (or even Editor.InsertImage()) double enter and then again. Or insert text between already inserted images.

The error could be also observed when accepting all changes.

The issue is reproducible when the style of the paragraph with the revisions is changed for the second time.

RadRichTextBox doesn't render a border that is not locally defined. In this case, the corresponding border from the applied table style should be used.

• Each RichText element should contain a unique id. The id contains DateTime.UtcNow.Ticks. This format is requiring to know which RT elements were added from the last change.
• Export these ids into html as is and import.
• For compatibility, id should have a different attribute name, for example:
  

  <p data-telerik-id="Paragraph637567542110611335">
  	<span data-telerik-id="Span637567542110611345">
  		Test
  	</span>
  </p>

  Note: data-* is Global attribute name: https://www.w3schools.com/tags/att_data-.asp
  
  Id value example:
  

  public class HiResDateTime
  {
  	private static long lastTimeStamp = DateTime.UtcNow.Ticks;
  	private static readonly Regex digitsOnly = new Regex(@"[^\d]");
  	public static long UtcNowTicks
  	{
  		get
  		{
  			long original, newValue;
  			do
  			{
  				original = lastTimeStamp;
  				long now = DateTime.UtcNow.Ticks;
  				newValue = Math.Max(now, original + 1);
  			} while (Interlocked.CompareExchange
  						 (ref lastTimeStamp, newValue, original) != original);
  
  			return newValue;
  		}
  	}
  
  	public static string UtcNowTicksString => digitsOnly.Replace(UtcNowTicks.ToString(), "");
  }

  
  

Currently, there is a DocumentHistory property IsEnabled indicating whether the history for the RadDocument is enabled. This property is not working and history cannot be disabled.

Workaround:

Use DocumentHistory Clear() method by attaching to editor's CommandExecuted event.

        private void Editor_CommandExecuted(object sender, Telerik.Windows.Documents.RichTextBoxCommands.CommandExecutedEventArgs e)
        {
            editor.Document.History.Clear();
        }

Add support for shapes, and especially for shapes with textual content. 
In OOXML, shapes are represented by the wps:wsp element, and shapes with textual content by <wps:txbx>, <w:txbxContent>.
Such shape can be added to a Word document using the Insert -> Text -> Text Box -> Draw Text Box, or through a shape's context menu -> Add Text.

Note: Do not confuse with Text/Rich Text content controls (https://feedback.telerik.com/Project/143/Feedback/Details/113730 ).
