System.Windows.Data Error: 2 : Cannot find governing FrameworkElement or FrameworkContentElement for target element. BindingExpression:(no path); DataItem=null; target element is 'SolidColorBrush' (HashCode=63604780); target property is 'Color' (type 'Color')

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;

Showing a document that contains a Table object without any TableRow inside leads to NullReferenceException.

Workaround: After importing the document, remove the tables that don't have content:

foreach (var table in document.EnumerateChildrenOfType<Table>())
{
    if (table.Rows.Count < 1)
    {
        table.Parent.Children.Remove(table);
    }
}

As suggested in the orginal support ticket 1430154 I'm opening a separate bug reprot for the RadRichTextBox.

Visual Studio 2019 solution to reproduce the problem is attached to the bug report.

Currently floating images specified using the VML shapes are imported as non-floating, for example:

<v:shape id="_x0000_s1026" type="#_x0000_t75" style="height:180.25pt;margin-left:62.25pt;margin-top:1.65pt;position:absolute;width:180.25pt;z-index:251658240" o:preferrelative="t">
        <v:imagedata r:id="rId4" />
</v:shape>

Right click image > text wrapping > more layout options > text wrapping tab

Word supports "Largest Only" but RichTextBox only has both, left, and right.

When importing from a .docx the RichTextBox is adding a blank line for each continuous section break. You can see this in the attached file - in the RichTextBox there is an extra line between sections that does not exist in the source word document.

This can be reproduced with the provided .docx. In Word the image floats in the empty space below the text but the RichTextBox has it inline and overlapping text.

Removing the rectangle from around the image in the source document has no affect.
