Example

The following example demonstrates how to construct an object of the CMFCHeaderCtrl class, and how to enable multiple column sort mode for the current header control.

    CMFCHeaderCtrl* headerCtrl = new CMFCHeaderCtrl();
    headerCtrl->EnableMultipleSort();

Remarks

The CMFCHeaderCtrl class draws a sort arrow on a header control column to indicate that the column is sorted. Use multiple column sort mode if a set of columns in the parent list control (CMFCListCtrl Class) can be sorted at the same time.
