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.

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.

The exception is thrown while typing and is with message "Value cannot be null. Parameter name: insertIMETextCommandContext". 

The exception is thrown in RadDocument.IsInNonEditableRange() method, which is called before measuring the document. When using a format provider, the error is thrown but the document can still be opened in RichTextBox. In binding scenario, the document is not imported.

Workaround: Ensure the document is measured before assigning it to RadRichTextBox.

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

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

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

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.

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. 

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.

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,

Hi Guys,

Our application works with a document storage and we use RadRichTextBox to allow users edit and view the documents. Unfortunately, many documents cannot be opened due to the following exception we get:

Unable to cast object of type 'Telerik.Windows.Documents.Model.FieldRangeStart' to type 'Telerik.Windows.Documents.Model.AnnotationRangeEnd

As result we receive complains from our users. Could you please facilitate with solving it? 

I have attached a simple test application with the problematic document as well the stacktrace. 

Best regards,

Yaroslav 

The exception is thrown due to an empty byte[] which is applied to the image source.

Hello,

   We found a problem when using the radrichtextbox control. When radrichtextbox is enabled to cancel input, error will be reported using the sougou Chinese input method. This problem will not occur in the English input method. Please help solve it. Thank you very much.

Memory leak caused by the section columns dialog

Currently, when importing an RTF document that does not conform to RTF syntax an exception is thrown.

Telerik.Windows.Documents.FormatProviders.Rtf.Exceptions.RtfUnexpectedElementException: 'Exception of type 'Telerik.Windows.Documents.FormatProviders.Rtf.Exceptions.RtfUnexpectedElementException' was thrown.'

Xaml exported in Net Core app cannot be imported with Net Framework app

This behavior is observed when copy and paste a Chinese text wrapped in a bookmark.

Steps to reproduce:
1. Import the attached document (testDocument.docx)
