virtual void GetSortKey(ROWCOL nRow, ROWCOL nCol, const CGXSortInfo& sortInfo, const CGXStyle& style, CString& sKey);
nRow
Specifies the row id.
nCol
Specifies the column id.
sortInfo
This is the sort information. See SortRows for information about CGXSortInfo.

This method is called to return the sort key for a given cell. By default, GetSortKey will return the value of the cell. Override CGXControl::GetSortKey or CGXGridCore::GetSortKey if you want to return a different sort key, e.g., if you have a date control you could convert the date into a number. With a currency control, you could remove the leading ‘$’ so the sort key is recognized as a numeric value.
