问题描述
我正在使用Delphi 2010和TListView列出名称和其他数据。前两列是姓氏和名字
I am using Delphi 2010 and TListView to list Names and other data. The first two columns is the Last Name & First Name
标题=姓氏 子项[0] =名字
Caption = Last Name SubItems[0] = First Name
如何按这两列对ListView进行排序?这些只是Listview的排序依据,我想一直保持这种排序(添加,编辑,删除项目时)
How do I sort the ListView by these two columns? These will only be the columns the Listview will be sorted by and I would like to always keep the sort as such (when adding, editing, deleting items)
推荐答案
将 SortType 设置为'stBoth',并实施 OnCompare 事件处理程序。示例:
Set SortType to 'stBoth', and implement an OnCompare event handler. Example:
procedure TForm1.ListView1Compare(Sender: TObject; Item1, Item2: TListItem; Data: Integer; var Compare: Integer); var S1, S2: string; begin S1 := Item1.Caption; if Item1.SubItems.Count > 0 then S1 := S1 + Item1.SubItems[0]; S2 := Item2.Caption; if Item2.SubItems.Count > 0 then S2 := S2 + Item2.SubItems[0]; Compare := CompareText(S1, S2); end;更多推荐
