GridControl中添加下拉列表列RepositoryItemComboBox

今天在用GridControl中添加下拉列表遇到些问题，总结出来.项目需求是在GRIDcontrol显示用户信息，其中一列是性别，做成下拉列表，并可以选择。数据库中用int类型表示性别，但是gridcontrol中的下拉列表列RepositoryItemComboBox貌似不支持值和文字显示的功能，或许我还没找到，不过现在用一个变通的办法来解决，

性别 0男 1女,-1请选择

我在用户实体类中添加了一个字段，用于表示性别对应的文字描述。

代码如下

using DevExpress.XtraEditors.Controls;using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Linq;using System.Text;using System.Threading.Tasks;using System.Windows.Forms;namespace WindowsFormsApplication1{    public partial class Form2 : Form    {        List<User> list = new List<User>();        public Form2()        {            InitializeComponent();        }        /// <summary>        /// 页面加载        /// </summary>        /// <param name="sender"></param>        /// <param name="e"></param>        private void Form2_Load(object sender, EventArgs e)        {            repositoryItemComboBox1.TextEditStyle = DevExpress.XtraEditors.Controls.TextEditStyles.DisableTextEditor;            repositoryItemComboBox1.Items.Add("请选择");            repositoryItemComboBox1.Items.Add("男");            repositoryItemComboBox1.Items.Add("女");            list.Add(new User { Id = 1, UserName = "张三", Sex = 0, SexDes = "男" });            list.Add(new User { Id = 2, UserName = "李四", Sex = 0, SexDes = "男" });            list.Add(new User { Id = 3, UserName = "赵娅", Sex = 1, SexDes = "女" });            list.Add(new User { Id = 3, UserName = "王林", Sex = -1, SexDes = "请选择" });            this.gridControl1.DataSource = list;        }        /// <summary>        /// 获取选择的内容        /// </summary>        /// <param name="sender"></param>        /// <param name="e"></param>        private void button1_Click(object sender, EventArgs e)        {            for (int i = 0; i < gridView1.RowCount; i++)            {                User user = (User)gridView1.GetRow(i);                if (user.SexDes=="请选择")                {                    user.Sex = -1;                }                if (user.SexDes == "男")                {                    user.Sex =0;                }                if (user.SexDes == "女")                {                    user.Sex =1;                }                MessageBox.Show(user.SexDes);            }        }    }    public class User    {        public int Id { get; set; }        /// <summary>        /// 名称        /// </summary>        public string UserName { get; set; }        /// <summary>        /// 性别0男 1女,-1请选择        /// </summary>        public int Sex { get; set; }        /// <summary>        /// 描述        /// </summary>        public string SexDes { get; set; }        }}
