>In my grid class I allow users to sort on up to 3 columns by clicking in the headers. I convert all the fields to characters in order to string them together. For example, the code might look something like:

Maybe you can add a sign flag to the string with iif(x<0,'A','B') or something like that. Then negative values are lower then positive ones.
