I need to edit an ascx file's content with CKEditor. The content of ascx is mostly pure html code. It also has a custom tags in it (I use a custom framework and its own custom tags, ie: )
CKEditor erases those custom tags automatically (since they are not valid HTML codes).
How can I add/define framework's custom tags into CKEditor so it would not erase them.
PS: those custom tags don't need to be rendered in HTML view as long as they stay in the source code.
