网上搜索的例子加自己的一点点补充

lookupedit 设置选项值：

private void LookUpEditFormTest_Load(object sender, EventArgs e)            {                IList
     
       list = HiscashsService.GetTableCovList();                this.comboBoxEdit1.Properties.DataSource = list;                this.comboBoxEdit1.Properties.DisplayMember = "EN_CURRENT_BALANCE";                this.comboBoxEdit1.Properties.ValueMember = "I_ENTER_DATE";                        comboBoxEdit1.Properties.Columns.Add(new LookUpColumnInfo("I_ENTER_DATE", "日期", 20));                comboBoxEdit1.Properties.Columns.Add(new LookUpColumnInfo("EN_CURRENT_BALANCE", "当前金额", 80));                //comboBoxEdit1.ItemIndex = 0;//选择第一项                comboBoxEdit1.ItemIndex = -1;  //无选项，此时显示的是nulltext值　其实这个地方只要editvalue==null，lookupedit就显示nulltext                }                private void comboBoxEdit1_EditValueChanged(object sender, EventArgs e)            {                string name = this.comboBoxEdit1.SelectedText;                string value = this.comboBoxEdit1.EditValue.ToString();//自动搜索datasouse，选择与之匹配的值，没有的情况下赋值null ,value的值必须与valuemember的数据类型一致。                MessageBox.Show(name+"==="+value);            }   /* 何问起 hovertree.com */

checkedComboBoxEdit 设置选项值:

public void TestFunc()        {            for (int i = 0; i < IniFunc().Count; i++)            {                if (IniFunc()[i].Isno == true)                    checkedComboBoxEdit1.Properties.Items.Add(i, IniFunc()[i].Name, CheckState.Checked, true);                else                    checkedComboBoxEdit1.Properties.Items.Add(i, IniFunc()[i].Name, CheckState.Unchecked, true);            }                //取消第二列的选中状态            checkedComboBoxEdit1.Properties.Items[1].CheckState = CheckState.Unchecked;            //checkedComboBoxEdit1            MessageBox.Show(this.checkedComboBoxEdit1.SelectedText + "===" + this.checkedComboBoxEdit1.EditValue.ToString());        }                    public BindingList IniFunc()        {            BindingList bindlist = new BindingList();            bindlist.Add(new Data { ID = 1, Name = "科比", Isno = true });            bindlist.Add(new Data { ID = 2, Name = "艾佛森", Isno = false });            bindlist.Add(new Data { ID = 3, Name = "姚明", Isno = false });            bindlist.Add(new Data { ID = 4, Name = "韦德", Isno = true });            bindlist.Add(new Data { ID = 5, Name = "詹姆斯", Isno = true });            return bindlist;        }    }        public class Data    {        public int ID { get; set; }        public string Name { get; set; }        public bool Isno { get; set; }    } /* 何问起 hovertree.com */

补充： checkedComboBoxEdit 多选设置

反绑定重点：

DevExpress.XtraEditors.CheckedComboBoxEdit  cmb_check_CKID = new DevExpress.XtraEditors.CheckedComboBoxEdit();       private void GetAllCK()          {              List
     
       list = (List
      
       )serviceLocator.GetService
       
        ().GetAllStore(StaticUser.ConmanyID);//
        LISt数据源              cmb_check_CKID.Properties.DataSource = list;              cmb_check_CKID.Properties.DisplayMember = "STORENAME";              cmb_check_CKID.Properties.ValueMember = "ID";              cmb_check_CKID.Properties.SeparatorChar = ','; //
        逗号 隔开   存储的 值是 编号(ID)如 2，3，4          }  this.cmb_check_CKID.RefreshEditValue();//反绑定的 时候 这句很重要/* 何问起 hovertree.com */
