绑定方法1：追加Items的方式（建议采用绑定方式）
//清空项
checkedComboBoxEdit1.Properties.Items.Clear();
checkedComboBoxEdit1.Properties.Items.Add(1, "新建");
checkedComboBoxEdit1.Properties.Items.Add(2, "审批中");
checkedComboBoxEdit1.Properties.Items.Add(3, "已完成");
checkedComboBoxEdit1.Properties.Items.Add(4, "已撤销");
foreach (DevExpress.XtraEditors.Controls.CheckedListBoxItem cbi in this.checkedComboBoxEdit1.Properties.Items)
{
if (cbi.Value.Equals(2) || cbi.Value.Equals(1))
{
cbi.CheckState = CheckState.Checked;
}
}
绑定方法2：绑定数据源的方式（注意这种绑定方式，Popup事件里才可以获取this.checkedComboBoxEdit1.Properties.Items的真实数值，并且无法设置具体项目的CheckState）
List<DepartmentInfo> list_departments = new List<DepartmentInfo>();
list_departments = DataFactory.GetDepartmentList();
this.checkedComboBoxEdit1.Properties.DataSource = list_departments;
this.checkedComboBoxEdit1.Properties.DisplayMember = "DepartmentName";
this.checkedComboBoxEdit1.Properties.ValueMember = "DepartmentID";
