For example,

6/24/2014 | a
-----------------------
6/25/2014 | b
-----------------------
6/26/2014 | c
-----------------------
6/26/2014 | c
-----------------------

Why? Is it duplicate data? Isn't it better to prevent duplication in first place, instead of "merging"?

How do you retrieve the data? Maybe you can edit your query to GROUP BY.

Are you maby using the DataGridView to just present Data to users? In that case a Report would be bether than a DataGridView. Othervise as @Milfje mentionet update your SQL Statement to use GROUP BY.
