自己整理了下,一些小细节要注意,否则没有效果哦!

1、新建winform项目：PopupApplication

2、添加引用，引用上面下载的dll文件

3、因为要显示数据，所以这里需要构造一个数据源，因此我建了一个对象Student，属性：SId,SCode,SName,SAge,SAddress

namespace PopupApplication{    public class Student    {        public int SId { get; set; }        public string SCode { get; set; }        public string SName { get; set; }        public int SAge { get; set; }        public string SAddress{get;set;}    }}

4、创建用户控件：StudentListControl

5、在用户控件中添加一个DataGridView命名：dgvStudentList 和TextBox命名：txtKeys，DataGridView是用来显示数据列表的，TextBox是用来让用户输入关键字用来检索信息用的

如图：

这个地方要注意把RowHeadersVisible属性，将其设置为False就OK。

然后要设置

his.dataGridView1.SelectionMode =DataGridViewSelectionMode.FullRowSelect;

下面的点击才会有效果

构建数据源并绑定数据，代码：

private List<Student> _dataList = new List<Student>();        private TextBox _txtBox;        public StudentListControl(TextBox txtBox)        {            InitializeComponent();            _txtBox = txtBox;            _dataList = GetDataList();        }        private void StudentListControl_Load(object sender, EventArgs e)        {            dgvStudentList.DataSource = _dataList;        }        /// <summary>        /// 构造数据源        /// </summary>        /// <returns></returns>        private List<Student> GetDataList()        {            List<Student> stList = new List<Student>();            stList.Add(new Student() { SId = 1, SName = "张阳", SAge = 15, SCode = "zy", SAddress = "广东省中山市9999999" });            stList.Add(new Student() { SId = 2, SName = "欧阳新文", SAge = 17, SCode = "oyxw", SAddress = "广东省广州市99" });            stList.Add(new Student() { SId = 3, SName = "宇文化及", SAge = 18, SCode = "ywhj", SAddress = "广东省湛江市2222" });            stList.Add(new Student() { SId = 4, SName = "温斯特梅拉", SAge = 19, SCode = "wstml", SAddress = "广东省茂名市" });            stList.Add(new Student() { SId = 6, SName = "唐兵", SAge = 24, SCode = "tb", SAddress = "四川省阆中市555555555555" });            stList.Add(new Student() { SId = 8, SName = "杨红军", SAge = 24, SCode = "yhj", SAddress = "四川省乐山市22222222222222222222" });            stList.Add(new Student() { SId = 11, SName = "张翠山", SAge = 23, SCode = "zcs", SAddress = "四川省南充市7777777777777777" });            stList.Add(new Student() { SId = 12, SName = "张三丰", SAge = 27, SCode = "zsf", SAddress = "广东省中山市555" });            stList.Add(new Student() { SId = 13, SName = "何月", SAge = 28, SCode = "hy", SAddress = "广东省中山市88888" });            stList.Add(new Student() { SId = 14, SName = "何宝生", SAge = 32, SCode = "hbs", SAddress = "广东省中山市77" });            stList.Add(new Student() { SId = 15, SName = "王家新", SAge = 33, SCode = "wjx", SAddress = "广东省茂名市8" });            stList.Add(new Student() { SId = 23, SName = "肖月伦", SAge = 34, SCode = "xyl", SAddress = "广东省茂名市7777777" });            stList.Add(new Student() { SId = 22, SName = "王岳伦", SAge = 25, SCode = "wyl", SAddress = "广东省中山市888888888888" });            stList.Add(new Student() { SId = 24, SName = "紫阳红玉", SAge = 45, SCode = "zyhy", SAddress = "四川省南充市2" });            stList.Add(new Student() { SId = 27, SName = "雷小兵", SAge = 30, SCode = "lxb", SAddress = "广东省中山市999999999999999" });            stList.Add(new Student() { SId = 28, SName = "张郭老", SAge = 18, SCode = "zgl", SAddress = "四川省南充市333333333333333333333333" });            stList.Add(new Student() { SId = 30, SName = "汤小雨", SAge = 24, SCode = "txy", SAddress = "四川省乐山市333333333333" });            stList.Add(new Student() { SId = 31, SName = "吴志胜", SAge = 26, SCode = "wzs", SAddress = "四川省乐山市33" });            stList.Add(new Student() { SId = 32, SName = "伍国天", SAge = 32, SCode = "wgt", SAddress = "四川省阆中市6666" });            stList.Add(new Student() { SId = 33, SName = "朱新朝", SAge = 33, SCode = "zxz", SAddress = "四川省阆中市666666666666666" });            return stList;        }

7、给txtKeys控件添加TextChange事件：

private void txtKeys_TextChanged(object sender, EventArgs e)        {            if(string.IsNullOrEmpty(txtKeys.Text))            {                return;            }            var resultList = _dataList.FindAll(std=>std.SName.Contains(txtKeys.Text) || std.SAddress.Contains(txtKeys.Text));            dgvStudentList.DataSource = resultList;        }

8、给dgvStudentList添加点击事件，当点击列表的时候需要把选中的值显示到需要显示选中值的TextBox中

private void dgvStudentList_Click(object sender, EventArgs e)        {            if (dgvStudentList.RowCount > 0 && dgvStudentList.SelectedRows.Count > 0)            {                DataGridViewCell nameCell= dgvStudentList.CurrentRow.Cells["ColumnSName"];                DataGridViewCell addressCell = dgvStudentList.CurrentRow.Cells["ColumnSAddress"];                string strName = nameCell != null && nameCell.Value != null ? nameCell.Value.ToString() : "";                string strAddress = addressCell != null && addressCell.Value != null ? addressCell.Value.ToString() : "";                _txtBox.Text = string.Format("{0},{1}",strName,strAddress);            }        }

9、在Form1界面添加TextBox控件命名：txtSelectValue,添加如下代码：

public partial class Form1 : Form    {        public Form1()        {            InitializeComponent();        }        private void txtSelectValue_Click(object sender, EventArgs e)        {            StudentListControl uc = new StudentListControl(txtSelectValue);            Popup pop = new Popup(uc);            pop.Show(txtSelectValue, false);        }    }

最后效果如下图
