Pasting style from Word with accent letters in the name is not properly displayed in the Styles Gallery. For example, pasting word style named "Estàèélo1" will be displayed as "Estаийlo1". 

Styles which contain "Headind1", "Headind2", "Headind3", "Headind4", "Headind5", "Heading6" in their names are exported as <h> elements to HTML. 

Moreover, is specific cases when the style of the name ends with specific symbols which are not allowed for element names in XML/HTML, e.g. "Heading1?", an ArgumentException is thrown.

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.

System.InvalidOperationException: Cannot use a DependencyObject that belongs to a different thread than its parent Freezable. is thrown when multiple RadRichTextBoxes are instantiated in different STA threads. The cause seems to be a static freezable resource.

In this example, the current synchronization context is "occupied" by the task that sets the RTF string forcing the arrange tasks to wait for it to complete before they can start. However, it can never complete as it is blocked by the wait call for the arrange tasks that will never run, causing a deadlock.

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

Having a watermark test "This is a\nWatermark" is exported with an empty box instead of a new line to PDF.

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.

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

Bullet and numbered lists are still displayed as toggled in the ribbon even though the user has broken the lists. The toggle is removed only when the user clicks over the document.

Missing bookmark annotation after cut command or move selected text which includes bookmark annotation

HTML export of RadRichTextBox to perform font-size export in different units.

If you export a document using the HtmlFormatProvider, all style properties which contain measurement units are exported in pixel units. This makes the exported documents look much smaller when opened on devices with higher pixel density.

WORKAROUND: use Regex to find, convert and replace the font-size attributes

            HtmlFormatProvider html = new HtmlFormatProvider();
            string res = html.Export(document);
            Regex regex = new Regex(@"font-size: [0-9]*\.?[0-9]*px");
            Match match = null;

            do
            {
                match = regex.Match(res);
                if (!match.Success)
                {
                    break;
                }

                string value = match.Value.Substring("font-size: ".Length, match.Value.Length - "font-size: ".Length - "px".Length);
                double pts = double.Parse(value) * 72 / 96;
                res = res.Replace(match.Value, @"font-size: " + Math.Round(pts, 4) + "pt");
            } while (match.Success);

            File.WriteAllText("output.html", res);

It should be located on a new line. Instead, it is located on the same line where the text is.

1. Open RadRichTextBox
2. Click to Home tab -> Paragraph group-> Multilevel list button
4. Click to "Define New List Style"
5. In "Apply formatting to" select 4th level. Don't select '1','2','3' beforehand, select '4' right after '1'st level.

Observed result: All text except the 4th level is bold.

Expected result: Only 4th level text is bold.

To reproduce:

• Create two lists one after another
• Select the second by using the keyboard 
• Press delete and then Ctrl+z (undo)

This works fine when the list is selected with the mouse. 

To reproduce: 

protected override void OnClosing(CancelEventArgs e)
{
    this.radRichTextBox.Document = null;
    base.OnClosing(e);
}

RichTextBox: wrong content when pasting RTF with an encoding other than utf-8.

Support should be implemented for importing height CSS property applied to HTML table cells.

Use Destination styles does not appear in the paste options popup control. It only appears in the RadRibbonDropDownButton.

When a hyperlink uri contains a symbol that needs to be escaped (e.g. ')'), the exported document is corrupted.
