How to do?
It doesn't matter. You could implement the interface on any object.
I usually like to create a class specifically for the IComparer implementation, but some people like to implement it on some exiting class like the Form.

Hi,
You can do this in a couple of different ways. I assume that, whether the column is grouped or not, you always want to sort the column in the same order. So the easiest thing to do would to create a class that implements IComprer and set the SortComparer on the column to an instance of that class.
