This is about CExtGridWnd. I’ve been reading your support posts and answers about sorting columns.
I want to know if there is a ’compare’ method we can override or supply to control the way a column is sorted -- much like how a predicate can be passed in the C++ standard algorithm ’sort’ to define a rule how comparisons execute.
Is there such a way? What I see so far is only to sort in ascending/descending and in combination with other columns.
Thanks in advance

You can implement your own grid cell class and override CExtGridCell::CompareEx virtual method to have your custom algorithm.
