[DevExpress]为LookUpEdit添加删除按钮

关键代码：

        public static void AddDeleteButton(this LookUpEdit lue, string prompttext)
        {
            prompttext = string.IsNullOrEmpty(prompttext) ? "删除选中项" : prompttext;
            lue.Properties.Buttons.AddRange(new EditorButton[]
            {
                new EditorButton(
                    ButtonPredefines.Delete,
                    "删除", -1, true, true, false, ImageLocation.MiddleCenter,
                    null,
                    new KeyShortcut(Keys.Delete),
                    new SerializableAppearanceObject(),
                    prompttext,
                    "Delete",
                    null,
                    true)
            });
            lue.ButtonClick += new ButtonPressedEventHandler(lue_ButtonClick);
        }
        static void lue_ButtonClick(object sender, ButtonPressedEventArgs e)
        {
            if (e.Button.Kind == ButtonPredefines.Delete)
            {
                LookUpEdit _curLue = sender as LookUpEdit;
                _curLue.EditValue = null;
            }
        }

使用示例：

            this.lookUpEdit1.BindWithAutoCompletion(PersonList, "Name", "Name", "输入需要搜索的....");
            this.lookUpEdit1.AddDeleteButton("删除选中数据....");
