Today I’ll talk about a problem that may occur when you edit a list in « DataSheet View».
It may occurs that you got the error message “The selected cells are read-only.” In fact, this message appears if you try to edit a column of type “Multiple lines of text” with the type “Enhanced rich text” (selected by default).
In fact, if you specify the type “enhanced” for multiline field you cannot modify it in “DataSheet View”!
Hope this helps

Such a common problem this, big throwback to SharePoint 2007.
