Question

我在C＃WinForms应用程序中使用ListView控件。列表中的项目将添加到ListViewGroup（在本例中，按国家/地区分组）。没有按预期工作的一件事是列排序似乎很奇怪。

我已经连接到ListView的ListViewItemSorter属性，所有内容都完美排序，除非country列按降序排序（即Z-A）。无论列表排序如何发生，组都按升序显示。

有人能给我一个正确方向的推动吗？

Answer 1

在ColumnClick事件中试一试：

    // Determine whether the column is the same as the last column clicked.
    if (e.Column != sortColumn)
    {
        // Set the sort column to the new column.
        sortColumn = e.Column;
        // Set the sort order to ascending by default.
        listView1.Sorting = SortOrder.Ascending;
    }
    else
    {
        // Determine what the last sort order was and change it.
        if (listView1.Sorting == SortOrder.Ascending)
            listView1.Sorting = SortOrder.Descending;
        else
            listView1.Sorting = SortOrder.Ascending;
    }

    // Call the sort method to manually sort.
    listView1.Sort();
    // Set the ListViewItemSorter property to a new ListViewItemComparer
    // object.
    this.listView1.ListViewItemSorter = new ListViewItemComparer(e.Column,
                                                      listView1.Sorting);

Answer 2

小组应单独分类

        // save groups
        ListViewGroup[] oGroups = new ListViewGroup[list.Groups.Count];
        list.Groups.CopyTo(oGroups, 0);
        list.Groups.Clear();

        // restore groups
        switch (groupSortOrder)
        {
            case SortOrder.Ascending:
                list.Groups.AddRange(oGroups.OrderBy(x => x.Name).ToArray());
                break;
            case SortOrder.Descending:
                list.Groups.AddRange(oGroups.OrderByDescending(x => x.Name).ToArray());
                break;
            default:
                list.Groups.AddRange(oGroups);
                break;
        }

查看ObjectListView - 使用起来会更容易。

ListViewGroup未正确排序
