How To Replace Cell Value

I currently have a sql command that inserts info into a table through one of my statements. One of the tables columns is defined as an integer. The integer value inside that columns cell's is one that I would like to retrieve, and then set it to a value my enumeration (a string value) and later display on my datagridview.

The problem I am having is that when I retrieve the column's value from the table(let's say 1) I can't set the value of the rows cell to my enumeration type, it tells me the table holds integer values only and so I can't change it to text. How can I accomplish retrieving my integer value, setting it to my enumeration type (a string value) and displaying it in my datagridview in the same cell that the integer was?
