大家好，又见面了，我是全栈君，今天给大家准备了Idea注册码。

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<Hiscashs> 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<Data> IniFunc()    
    {    
        BindingList<Data> bindlist = new BindingList<Data>();    
        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<TB_STORE> list = (List<TB_STORE>)serviceLocator.GetService<ITB_STOREBLL>().GetAllStore(StaticUser.ConmanyID);//<span style="color:#FF0000;"><strong>LISt数据源</strong></span>  
            cmb_check_CKID.Properties.DataSource = list;  
            cmb_check_CKID.Properties.DisplayMember = "STORENAME";  
            cmb_check_CKID.Properties.ValueMember = "ID";  
            cmb_check_CKID.Properties.SeparatorChar = ','; //<span style="color:#FF0000;">逗号 隔开</span>   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
