Hi support,

We have a problem when we copy a text from MS word to RitchTextBox.
If the text copied uses an style that the namecontains tilde, then style name on the ritchtextbox is broken with strange characters.
All works well with this strange characters, but if you export to html and then import to ritchtextbox, the style is lost ...

This is a big problem because in spanish, many styles have tildes. When our user copy content from word they have problem with html format export / import.

I Attach a MS Word docx with a style with tildes:

Steps to reproduce it:

1- Open MS Word attached.
2- Copy the content.
3- Open a ritchTextBox Editor
4- Paste the content.
5- Export to html
6- Import the html.

You can see now, that the style are lost, and the name of the style contains strange characters.

Similar issue its happen when open a Word Docx with styles with tildes from ritchTextBox, not include strange characters but the style is lost.


Thanks for you support,

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.

When an HTML document contains a div and a span just after it, the span is imported as a child of the div. As a result, the span inherits some of the settings applied to the div.

Release 2019.3.1007 (10/07/2019)
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.

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

ClipboardEx.SetDocument(new DocumentFragment(doc));

Ordered list are not pasted correctly.


Bypass paste and use the InsertFragment API

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

Showing a document which contains 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>().ToList())
    (table.Parent as Section).Blocks.Remove(table);

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.

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.

Placing the caret in a table cell containing a floating image only results in invisible caret. The formatting symbol of the TableCell is affected by the floating block as well - if there is no other content, the symbol appears under the image. When some text is inserted, the symbol is lost and clicking next to the paragraph end moves the caret in the next/previous table cell.
