I have changed the source code (this works fine):

void CXTPReportRows::Sort(bool bSortChildren)

{

    if (bSortChildren)

    {

         for(int i=0; i<GetCount(); ++i)

         {

               GetAt(i)->GetChilds()->Sort(bSortChildren);

         }

     }

      typedef int (_cdecl *GENERICCOMPAREFUNC)(const void *,const

      void*);

      qsort(m_arrRows.GetData(), (size_t)m_arrRows.GetSize(), sizeof    (CXTPReportRow*), (GENERICCOMPAREFUNC)CompareRows);

}

How to sort tree in ReportControl to sort subtrees also ? Has anyone know some fast way how to do that ? Now you can sort only the top most leaves in the tree.

Thank you for help, Haiku.
