Infragistics support suggested taking advantage of the ActiveAppearance and ActiveAppearanceEnabled properties on the cell itself, however, I'm stuck with an earlier version of Infragistics in which those properties were not implemented.
In the end I had to implement a custom draw filter for the cell using the IUIElementDrawFilter class. Examples of implementing IUIElementDrawFilter can be found at http://help.infragistics.com/Help/NetAdvantage/WinForms/2012.1/CLR2.0/html/Infragistics2.Win.v12.1~Infragistics.Win.IUIElementDrawFilter.html.
