    方法 1:控件  checkedComboBoxEdit

    ///清空选项

     checkedComboBoxEdit1.Properties.Items.Clear();

    ///添加选项

    checkedComboBoxEdit1.Properties.Items.Add("选项1-name", "选项1-description", CheckState.Checked, true);

    方法 2:

     

            /// <summary>
            /// 点击隐藏或显示选择框,并将所选内容显示在bte_status中
            /// bte_status为输入选择控件(ButtonEdit)
            /// checkedListBoxControl1为控件(checkedListBoxControl)
            /// </summary>
            /// <param name="sender"></param>
            /// <param name="e"></param>
            private void bte_status_ButtonClick_1(object sender, DevExpress.XtraEditors.Controls.ButtonPressedEventArgs e)
            {
                if (this.checkedListBoxControl1.Visible.Equals(true))
                {
                    this.checkedListBoxControl1.Visible = false;
                    ///获取选中的内容
                    string output = string.Empty;
                    for (int i = 0; i < checkedListBoxControl1.CheckedIndices.Count; i++)
                    {
                        output += checkedListBoxControl1.Items[
                        checkedListBoxControl1.CheckedIndices[i]].ToString() + ",";
                    }
                    //去掉最后的,号
                    if (output.Length > 0 && output.Substring(output.Length - 1).Equals(","))
                    {
                        output = output.Substring(0,output.Length - 1);
                    }
                    this.bte_status.Text = output;
                }
                else
                {
                    this.checkedListBoxControl1.Visible = true;
                    string output = string.Empty;
                    ///获取选中的内容
                    for (int i = 0; i < checkedListBoxControl1.CheckedIndices.Count; i++)
                    {
                        output += checkedListBoxControl1.Items[
                        checkedListBoxControl1.CheckedIndices[i]].ToString() + ", ";
                    }
                    //去掉最后的,号
                    if (output.Length > 0 && output.Substring(output.Length - 1).Equals(","))
                    {
                        output = output.Substring(0, output.Length - 1);
                    }
                    this.bte_status.Text = output;
                }
