C#绑定:如何在BindingList中禁用CurrencyManager,以便不维护当前项位置并且不发信号？

Question

我有两个数据包到同一个BindingList的ListBox.

问题是当从GUI更改所选项时,它正在改变BindingList中的位置,然后BindingList发信号通知另一个ListBox以更改其所选项.

所以我已经同步了两个ListBoxes Selected Item,这对我不利.

我想保持项目列表同步.没有光标位置.

如何禁用该光标以使其不被维护？

示例代码(只需在设计时向表单添加两个ListBox,并注册SelectedIndexChanged事件并使用按钮注册按钮单击事件):

public partial class Form1 : Form
{
    BindingList<string> list = new BindingList<string>();

    public Form1()
    {
        InitializeComponent();
    }

    private void Form1_Load(object sender, EventArgs e)
    {
        list.Add("bla1");
        list.Add("bla2");
        list.Add("bla3");

        this.listBox1.DataSource = list;
        this.listBox2.DataSource = list;
    }

    private void listBox1_SelectedIndexChanged(object sender, EventArgs e)
    {
        if (listBox1.SelectedIndex != -1)
            System.Diagnostics.Trace.WriteLine("ListBox1: " + listBox1.SelectedItem.ToString());
    }

    private void listBox2_SelectedIndexChanged(object sender, EventArgs e)
    {
        if (listBox2.SelectedIndex != -1)
            System.Diagnostics.Trace.WriteLine("ListBox2: " + listBox2.SelectedItem.ToString());
    }

    // Register this event to a button
    private void button1_Click(object sender, EventArgs e)
    {
        list.Add("Test");
    }
}

将此行添加到Form_Load:

this.listBox1.BindingContext = new BindingContext();
