you need tell listview how sorting.

in c#:

create comparer:

// implements manual sorting of items columns.  class listviewitemcomparer : icomparer {     private int col;     public listviewitemcomparer()     {         col = 0;     }     public listviewitemcomparer(int column)     {         col = column;     }     public int compare(object x, object y)     {         return string.compare(((listviewitem)x).subitems[col].text, ((listviewitem)y).subitems[col].text);     } } 

and invoke sorting calling:

this.listview1.listviewitemsorter = new listviewitemcomparer(colnum); 

where colnum index of column want sort.

example taken here: http://msdn.microsoft.com/en-us/library/system.windows.forms.listview.columnclick.aspx

and here's solution in vb.net:

create comparer:

' implements manual sorting of items columns.  class listviewitemcomparer     implements icomparer      private col integer       public sub new()         col = 0     end sub       public sub new(byval column integer)         col = column     end sub       public function compare(byval x object, byval y object) integer _        implements icomparer.compare         return [string].compare(ctype(x, listviewitem).subitems(col).text, ctype(y, listviewitem).subitems(col).text)     end function  end class 

and invoke sorting calling:

me.listview1.listviewitemsorter = new listviewitemcomparer(colnum) 

where colnum index of column want sort.
