Currently, the only customization that can be performed is using HyperlinkToolTipFormatString property of RadRichTextBox, which sets the format for all hyperlinks in the document of the control. It would be nice if it were possible to be able to set different tooltips. 

A reference in DocumentFragment to RadDocument (CopySource property) can cause a memory after copy-paste between RadDocument.

Workaround:

public static bool ReleaseClipboardExReferences(
    RadDocument document)
{
    dynamic clipboardEx = new DynamicProxyObject(typeof(ClipboardEx));

    if (clipboardEx.documentClipboardData?.CopySource is DynamicProxyObject copySource
        && object.ReferenceEquals(copySource.Instance, document))
    {
        clipboardEx.documentClipboardData = null;
        return true;
    }

    if (clipboardEx.CopiedDocumentFragment?.Fragment?.CopySource is DynamicProxyObject fragmentCopySource
        && object.ReferenceEquals(fragmentCopySource.Instance, document))
    {
        clipboardEx.CopiedDocumentFragment = null;
        return true;
    }

    return false;
}

When the copied document fragment is replaced during paste within a single RadDocument:

ClipboardEx.SetDocument(new DocumentFragment(doc));

Ordered list are not pasted correctly.

Workaround:

Bypass paste and use the InsertFragment API

this.radRichTextBox.InsertFragment(new DocumentFragment(doc));
e.Cancel = true;

Use the attached project to reproduce:

- Click the first button so the image is changed

- Click the second button and examine the exported HTML

Expected: the Uri is exported

Actual: the Uri is not exported.

Workaround: 

When the MEF catalog of RadRichTextBox is predefined, the PasteOptionsPopup is not automatically loaded and causes NullReferenceException in the presenter when the users press Ctrl or Esc.

Workaround: Add typeof(PasteOptionsPopup) to the catalog.

The document styles are not respected because of wrongly imported custom style name after copy-paste from MS Word and exported to HTML.

Workaround: avoid using styles with braces in their name.

To reproduce:

- Select several words by holding the control key. 

- Paste some text. 

Result: the first word is replaced, the other are deleted

Expected: the text should be pasted in all selected places

Workaround:
