c# - 像 Google 搜索一样搜索组合框

Question

我正在制作一个 Windows 窗体，因为我有一个组合框，我已经从 SQL Server 2010 向其中加载了一些“发票编号”。我想在用户输入组合框时显示发票编号。例如，如果用户键入“100”，则应在下拉列表中显示以“100”开头的发票编号。

请帮助，提前致谢...

    DataTable temp;
    DataTable bank;
    private void Form1_Load(object sender, EventArgs e)
    {
        comboBox1.AutoCompleteMode = AutoCompleteMode.SuggestAppend;
        comboBox1.AutoCompleteSource = AutoCompleteSource.ListItems;

        temp = DbRdRw.SqlDbRead("Select * from BankMaster", "BankMaster");

        DataView dtview = new DataView(temp);
        dtview.Sort = "BankName DESC";
        bank = dtview.ToTable();

        comboBox1.DataSource = bank;
        comboBox1.ValueMember = "BankName";
        comboBox1.DisplayMember = "BankName";
    }
