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.

Add ability for Import/Export of custom attributes to HTML.

An option that enables users to paste any rich text content as a picture of it.

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

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.

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. 

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.

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.

MS Word has support for line numbers (see attached file) but RichTextBox ignores them. Could we get support for Words line numbering options?

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.

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.

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.

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". 

This element serves as a frame and allows the element to be positioned as a floating element. More information about it is available in section 22.9.2.18 ST_XAlign (Horizontal Alignment Location) of Open Office XML.

To provide a functionality to crop the image to split its content in multiple pages. This preserves the whole image in the file, but when it is rendered it shows only the cropped image area.

Exporting RTF document breaks right to left text direction.

In MS Word, when the users type an asterisk or 1., the application recognizes that they are trying to start a bulleted or numbered list and modifies the content automatically. Expose such a functionality in RadRichTextBox as well.

Keyboard commands are not working for controls inside the InlineUIContainer. The reason for this is that RichTextBox is handling them.
The commands are: Left, Right, Backspace, Delete, Tab, Ctrl+C, Ctrl+V among others.

Workaround:
Attach custom event handler to the PreviewEditorKeyDown event of the RichTextBox. This event should set "e.SuppressDefaultAction = true" when the focus is in the InineUIContainer.

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,
