我怎样才能在ListView中取消选择项目？ [英] How can I unselect item in ListView?

问题描述

我有一对夫妇在这一个项目的ListView。当ListView控件失去焦点，最后选定ListViewItem的仍是选择带有灰色背景。
我想做到这一点的ListView.FocusLost，选择走了，因此ListView.SelectedIndexChanged事件将会发生。
任何想法？

I have a ListView with a couple of items in it. When the ListView looses focus, the last selected ListViewItem is still "selected" with a gray background.
I would like to achieve that on ListView.FocusLost, the selection is gone and therefore the ListView.SelectedIndexChanged event will occur.
Any ideas?

我使用.NET CF 3.5。

推荐答案

假设你是从父窗体/控制访问的ListView。

Suppose you are accessing the ListView from a parent form/control.

您可以在窗体的/控制的构造函数/ Load事件添加这块code：

You can add this piece of code in the form's/control's constructor/load event:

this.myListView.LostFocus += (s, e) => this.myListView.SelectedIndices.Clear();

好了，你的情况，你将取代该委托有：

Ok, so in your case, you would replace that delegate with:

if (this.myListView.SelectedIndices.Count > 0)
    for (int i = 0; i < this.myListView.SelectedIndices.Count; i++)
    {
        this.myListView.Items[this.myListView.SelectedIndices[i]].Selected = false;
    }

您可以给c进行更好的形式$ C $，顺便说一句。

You can give the code a nicer form, btw.
