ADD New HTML5 Docx Editor with Canvas/SVG for pixel-perfect rendering

I would like to suggest a new product for Telerik: a html5 document editor (so not a html editor) which can edit docx documents. Recently I stumbled on the new html5 document editor by Teamlab (see, which will get its first major release this summer. I think such a component would also be an excellent addition to the Telerik product line as well (and probably a nice competitive advantage), since you already have some experience with the SL RichTextBox. It's probably not an easy project, but in the many years I've been a Telerik customer, I've seen a number of amazing components been created, so please forgive me for the high expectations. Just to mention (and perhaps as extra fuel for your discussion with management ;-)), I would personally favour a new HTML5 based editor. The current ASP.NET AJAX RadEditor is great in what it does -> HTML editing. Docx editing is very different in my view, both feature-wise as in regards to user-experience. As you can see from the Teamlab editor, it for example includes pagination and printing. I think it uses a different method for rendering too, e.g. canvas/SVG for pixel-perfect rendering. Very important for users to have what they type and see displayed on the screen be exactly the same as what they print. Basically I'm suggesting a MS Word Light by Telerik, something I believe your current SL RichTextBox is as well.

Hi guys,

The feature request was declined due to lack of demand for it. There are only 6 votes for 7 years.

If we got more votes in the future, I am going to update its status to Under Review.

Best regards,

You should take a look at:

They are doing amazing work, I'm not sure which techniques they used to build it, but it's all html5 without plugins. You can even drag and drop a Word file into the editor.

Would be great if Telerik would build such a HTML5 Docx editor too (since you are also already working on an Excel editor).

The official W3C specification on the canvas tag lists a huge amount of disadvantages when implementing text editing controls that are using the canvas element and strongly suggests avoiding implementation of such:
