Why is the richtextbox for silverlight weaker than the richtextbox for asp.net?

[lixin]

Hi Telerik,
    I did a contrast between the three richtextboxes (For silverlight, WPF and asp.net) on the supports for following scenarios:
   

	For Silverlight	For WPF	For ASP.NET
Enterring text and formatting text	Support	Support	Support
Pasting a plain text segment	Support	Support	Support
Pasting a formatted text segment copied from a word doc with Chinese characters	Pasted a plain text segment	All Chinese characters turned into a pile of messy code	Support
Pasting a table copied from an excel doc with Chinese characters	Pasted a table without grid lines	Support	Support
Pasting a text segment copied from a web page with Chinese characters	Pasted a plain text segment	Support	Support
Pasting an image copied from a word doc	Pasting command is not available	Support	Pasting command is not available

	My first question is why the richtextbox for asp.net work better on some pasting scenarios than the richtextbox for silverlight. And I wanna use the richtextbox for silverlight, so my 2nd question is how to keep the format of the text segment copied from a word or excel doc when user try to past it within a richtextbox for silverlight. Looking forward to your reply, thank you!                                                                                                                                   simon

Sorry for the horrible layout of my last thread. I will attach a picture with this thread to show my contrast table.
In addition, I got a new trouble when I tried to enter Chinese characters in the richtextbox for silverlight using a Chinese IME. I can not enter anything!

Hi Simon,

Indeed, copy/pasting rich text (images, tables, formatted text) from an external source to RadRichTextBox will not work. The reason for that is Silverlight's limited clipboard which supports only in plain text. Unfortunately, this is a limitation of the platform so there is nothing we can do in this regard.
About the problematic copy/paste form word to RadRichTextBox under WPF - could you please open a support ticket and send us a sample word document, so that we can reproduce and investigate the problem.
About the problem with the input with the Chinise IME, we would appreciate if you could open a support ticket for that as well. It would be helpful to share some more information about which IME you are using and what is the errors(if  any) that you are getting.

Thank you for your cooperation.

Kind regards,
Alex
