C# 强制 ListBox 更新元素

Unfortunately, the data-binding in ListView doesn't support regular (item) change notification events (FooChanged / INotifyPropertyChanged). However, if you know about the change, you can get the list to re-bind itself. Since you are subclassing, you can call:

this.RefreshItems();

或单个项目:

this.RefreshItem(index);

否则，由于这不是公开的，您可以通过更改 DisplayMember 来模拟它:

Otherwise, since this isn't public, you can simulate it by changing the DisplayMember:

lb.DisplayMember = "";
lb.DisplayMember = "Bar";

可能有点 hacky，但它可以工作，并保持当前选择等(不像清除 DataSource).

A little hacky, maybe, but it works, and maintains the current selection etc (unlike clearing the DataSource).
