dev checkedcomboboxedit 怎么设置单选

checkedcomboboxedit 这个控件该怎么设置成为单选的那种呢？求大神指导
C# winform 开发

Answer 1

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);
}

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; }
}

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);//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
