WPF列表视图：列重新排序的事件吗？ [英] WPF Listview : Column reorder event?

问题描述

我需要同步2列表视图事件的列顺序，当用户更改的顺序。但似乎没有一个列重新排序的事件。

I need to sync the column order of two ListViews event when the user changes the order. But it seems there is not a Column reorder event.

有关的那一刻我只是做了AllowsColumnReorder =假，但不是长久之计。虽然搜索网，我发现很多人有同样的问题，但没有解决办法。有什么可以做？

For the moment I just did a AllowsColumnReorder="False" but that is not a permanent solution. While searching the net I found many people with the same problem but no solution. What can be done?

推荐答案

我不知道它的工作原理，但你可能可以采取的事实，即 GridView.Columns 是的ObservableCollection ：您可以订阅 Col​​lectionChanged 事件和处理的情况下，其中动作 = 移动

I'm not sure it works, but you could probably take advantage of the fact that GridView.Columns is an ObservableCollection : you could subscribe to the CollectionChanged event and handle the case where Action = Move

GridView gridView = (GridView)listView.View;
gridView.Columns.CollectionChanged += gridView_CollectionChanged;

private void gridView_CollectionChanged(object sender, CollectionChangedEventArgs e)
{
    if (e.Action == NotifyCollectionChangedAction.Move)
    {
        string msg = string.Format("Column moved from position {0} to position {1}", e.OldIndex, e.NewIndex);
        MessageBox.Show(msg);
    }
}
