Hi Jon,

>>We're finding that this simple inheritance after the fact doesn't work - probably because the children have already overridden the grid. Does anyone know of a simple way to achieve what we're after without having to redo all the work in the children classes? Maybe even a VCX hack?

Columns cannot be subclassed visually and changes in controls that reside in containers (which all columns do) cannot be inherited at all. Create the base column behavior that you desire in code (in a PRG file with DEFINE CLASS) and then add the columns that you want to inherit that behavior to the grid at runtime.
