[DevExpress]TreeList数据筛选

关键代码：

        public static void Filter(this TreeList tree, FilterCondition fc)
        {
            if (tree != null && fc != null)
            {
                if (!tree.OptionsBehavior.EnableFiltering)
                    tree.OptionsBehavior.EnableFiltering = true;
                tree.FilterConditions.Clear();
                tree.FilterConditions.Add(fc);
            }
        }

测试代码：

        private void Form1_Load(object sender, EventArgs e)
        {
            this.InitData();
            this.treeList1.DataSource = PersonList;
            this.lookUpEdit1.BindWithAutoCompletion(PersonList, "Name", "Name", "输入需要搜索的....");
            this.lookUpEdit1.AddDeleteButton("删除选中数据....");
            this.lookUpEdit1.KeyDown += new KeyEventHandler(lookUpEdit1_KeyDown);
        }
        void lookUpEdit1_KeyDown(object sender, KeyEventArgs e)
        {
            if (e.KeyCode == Keys.Enter)
            {
                Person _curPerson = lookUpEdit1.GetSelectedDataRow() as Person;
                FilterCondition _curFc = new FilterCondition(FilterConditionEnum.NotContains, treeList1.Columns["Name"], _curPerson.Name);
                treeList1.Filter(_curFc);
            }
        }
