Kyle's and Simon's answers are gross waste of CPU resources. CellFormatting and CellPainting events occur far too many times and should not be used for applying styles. Here are two better ways of doing it:

If your DataGridView or at least the columns that decide cell style are read-only, you should change DefaultCellStyle of rows in RowsAdded event. This event occurs only once when a new row is added. The condition should be evaluated at that time and DefaultCellStyle of the row should be set therein. Note that this event occurs for DataBound situations too.

If your DataGridView or those columns allow editing, you should use CellEndEdit or CommitEdit events to change DefaultCellStyle.
