I have a Gridview and I have a column heading named 'Locked'. The output is either a 'Y' or 'N'. I would like to have it substituted with an icon. So when it has a 'Y' I would like an icon of a green lock icon (Which I have in the ~\Content\Images folder). Also when it is a 'N' I would like to have it substituted with a Green Lock icon. This is very similar to Excel's icon conditional formatting. Any clues?
