让devexpress控件lookupedit绑定到实体属性
问题描述：
想实现这么一个效果，lookupedit绑定到一个数据源datatable上，通过实体的一个属性设置lookupedit选定值，同时lookupedit选择值能反映到实体的属性上。
实现代码如下：
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using DevExpress.XtraEditors;
using CimingHealthCare.Model;
using DevExpress.XtraEditors.Controls;
namespace LookUpEditUsage
{
public partial class XFMTextEditLookupedit : DevExpress.XtraEditors.XtraForm
{
public XFMTextEditLookupedit()
{
InitializeComponent();
PreIni();
this.UC_Initialize();
this.UC_Load();
}
private UserInfo _OT_SINGLE_CHECKINFOEntity = new UserInfo();
///<summary>
///个人基本信息
///</summary>
public UserInfo OT_SINGLE_CHECKINFOEntity
{
get
{
return _OT_SINGLE_CHECKINFOEntity;
}
set
{
_OT_SINGLE_CHECKINFOEntity = value;
}
}
public void UC_Initialize()
{
this.lookUpEdit1.Properties.DataSource = IniDataTable();
}
public void UC_Load()
{
this.textEdit1SglCheckID.DataBindings.Clear();
this.lookUpEdit1.DataBindings.Clear();
if (this._OT_SINGLE_CHECKINFOEntity !=null)
{
this.textEdit1SglCheckID.DataBindings.Add("EditValue",this._OT_SINGLE_CHECKINFOEntity, "Name");
this.lookUpEdit1.DataBindings.Add("EditValue",this._OT_SINGLE_CHECKINFOEntity, "ID");
}
else
{
this.textEdit1SglCheckID.EditValue =null;
this.lookUpEdit1.EditValue =null;
}
}
private void PreIni()
{
LookUpColumnInfo col =null;
col = new LookUpColumnInfo();
col.Visible = true;
col.FieldName ="FNAME";
col.Caption = "工作空间";
this.lookUpEdit1.Properties.Columns.Add(col);
this.lookUpEdit1.Properties.DisplayMember ="FNAME";
this.lookUpEdit1.Properties.NullText ="";
this.lookUpEdit1.Properties.ValueMember ="FID";
}
private DataTable IniDataTable()
{
DataTable dataTable4Connection;
dataTable4Connection = newDataTable();
dataTable4Connection.Columns.Add(newDataColumn("FID",typeof(string)));
dataTable4Connection.Columns.Add(newDataColumn("FNAME",typeof(string)));
DataRow dr;
dr = dataTable4Connection.NewRow();
dr["FID"] = "1";
dr["FNAME"] = "中原油田";
dataTable4Connection.Rows.Add(dr);
dr = dataTable4Connection.NewRow();
dr["FID"] = "2";
dr["FNAME"] = "新疆油田";
dataTable4Connection.Rows.Add(dr);
dataTable4Connection.AcceptChanges();
return dataTable4Connection;
}
private void simpleButton1_Click(object sender, EventArgs e)
{
//MessageBox.Show(this.textEdit1SglCheckID.Text + " " + this.lookUpEdit1.EditValue.ToString());
MessageBox.Show(this._OT_SINGLE_CHECKINFOEntity.Name +" " + _OT_SINGLE_CHECKINFOEntity.ID);
}
}
public class UserInfo
{
public string Name
{
get;
set;
}
public Int32 ID
{
get;
set;
}
}
}
