属性方式,项目中一些不用的代码

  public static string GetAllRole
        {
            get { return "[a-zA-Z0-9-]{1,20}"; }
        }

  MDataTable md = MDataTable.CreateFrom(rd.returndata);

                    //增加一行空的
                    //DataRow dr = dt.NewRow();
                    //dr["DEPARTMENTCODE"] = "0"; //使用0代替-1，避免出现节点的嵌套显示，因为-1已经作为了一般节点的顶级标识
                    //dr["PCODE"] = "-1";
                    //dr["DEPARTMENTNAME"] = "无";
                    //dt.Rows.InsertAt(dr, 0);

                    this.txtPCODE.Properties.TreeList.KeyFieldName = "DEPARTMENTCODE";
                    this.txtPCODE.Properties.TreeList.ParentFieldName = "PCODE";
                    this.txtPCODE.Properties.DataSource = md.ToDataTable();
                    this.txtPCODE.Properties.ValueMember = "DEPARTMENTCODE";
                    this.txtPCODE.Properties.DisplayMember = "DEPARTMENTNAME";

                    //this.textPCode.EditValue = "0";
