DevExpress中XtraTreeList的父子（層次）關係數據的綁定

select
   ABU01 AS [編碼]  --編碼
  ,ABU02 AS [名稱]  --名稱
  ,ABBRP AS [拼音]  --中文拼音縮寫
  ,ABBRW AS [五筆]  --中文五筆縮寫
  ,ABU01A AS [上級編碼]  --上級編碼
from
  ABU1

父子層次關係通過 [上級編碼]與[編碼]確定

則

 //獲取數據集
                DataView dvData = SqlHelper.ExecuteDataset(Pars.ConnStr, CommandType.Text, @"select ABU01 AS [編碼],ABU02 AS [名稱],ABBRP AS [拼音],ABBRW AS [五筆],ABU01A AS [上級編碼] from ABU1").Tables[0].DefaultView;
                //設置TreeList的父子關係
                treeList1.KeyFieldName = "編碼";
                treeList1.ParentFieldName = "上級編碼";
                //綁定數據源
                treeList1.DataSource = dvData;
                treeList1.ForceInitialize();
