Disabling FCKEditor Textbox??

I'm using the FCKEditor in asp.net. Is there any way to disable the users ability to edit the text contained within the FCKEditor textbox?

In my application, the FCKEditor textbox is pre-populated with text that the user selects from a list of articles however if the user selects certain articles, I must allow them to view the article in the editor but not allow them to edit it. The only way I can think of doing this is by disabling the textbox. Any ideas?

Thanks in advance.
