//这是个通用的过程

Item.Free;
finally
lv.Items.EndUpdate;

//此为调用过程，可以任意指定要移动的Item，下面是当前(Selected)Item
ListViewItemMoveUpDown(ListView1, ListView1.Selected, True, True);//上移
ListViewItemMoveUpDown(ListView1, ListView1.Selected, False, True);//下移
TListView组件使用方法
引用 CommCtrl单元
procedure TForm1.Button1Click(Sender: TObject);
begin
ListView_DeleteColumn(MyListView.Handle, i);//i是要删除的列的序号，从0开始
end;
用 LISTVIEW显示表中的信息：
procedure viewchange(listv:tlistview;table:tcustomadodataset;var i:integer);
begin
tlistview(listv).Items.BeginUpdate;{listv:listview名}
try
tlistview(listv).Items.Clear;
with table do{table or query名}
begin
active:=true;
first;
while not eof do
begin
listitem:=tlistview(listv).Items.add;
listitem.Caption:=trim(table.fields[i].asstring);
//listitem.ImageIndex:=8;
next;
end;
end;
finally
tlistview(listv).Items.EndUpdate;
end;
end;
