Rendering HTML Once Per Group of Controls...
Have a custom web control where 1..n controls can be dropped onto a webform. These are HTML editing controls and the text within the controls can be manipulated via a toolbar that appears at the top of the browser when a user is editing. They can do the usual bold, italic, etc.
I think you can render HTML using RegisterClientScriptBlock and RegisterStartupScript, but you can't control where it's rendered, so this may not solve your problem.
