    Help with gridview

    Newbie here, i have an asp.net web page with a gridview that has multiple columns with one of them being a 'Comments' column.
    I have an edit button in the gridview table as well, everything works great, even the editing. My question is, is it possible to be able to Edit the 'Comments' column at selected row and have the edited data attached to the existing data and use a different font to that added text? Any help would be appreciated.

    When you post code if you use the code tags which is the hash # button in the editor it will format your code, i have done it for you this time but if you could do that in future it would help everyone out
