如何在ListView中使用虚拟模式?

问题描述

我正在使用VirtualMode填充

List<ListViewItem> m_lstItem;


    private void Form1_Load(object sender, EventArgs e)
    {
        m_lstItem = Enumerable.Range(0, 100000).Select(X => new ListViewItem(new String[] { X.ToString(), (X + 1).ToString() })).ToList();
        listView1.VirtualListSize = m_lstItem.Count;
    }

    private void listView1_RetrieveVirtualItem(object sender, RetrieveVirtualItemEventArgs e)
    {
        e.Item = m_lstItem[e.ItemIndex];
    }

但是我无法访问所选的项目.访问所选项目时，抛出诸如Cannot access the selected items collection when the ListView is in virtual mode.

but i can not access the selected item. while accessing the selected item its throwing an error like Cannot access the selected items collection when the ListView is in virtual mode.

当listView位于VirtualMode

请帮助我做到这一点.
