C# devExpress GridControl 行中行 子行 多级行

在工作中经常会碰到需要做行中行，多级行的情况，不熟的情况下，我也只能试着实现.

命名空间

using DevExpress.XtraEditors.Repository;using System.Data.SqlClient;

实现代码

一下实现的也只是一个demo，大家不要拘泥于数据

   DB db = new DB();            DataSet ds = new System.Data.DataSet();            SqlCommand comm2 = new SqlCommand(sql, db.getSqlConnection());  //db.getSqlConnection() 返回一个sqlConnection 对象            SqlCommand comm3 = new SqlCommand(sql1, db.getSqlConnection());            SqlCommand comm4 = new SqlCommand(sql2, db.getSqlConnection());            SqlDataAdapter da2 = new SqlDataAdapter(comm2);            SqlDataAdapter da3 = new SqlDataAdapter(comm3);            SqlDataAdapter da4 = new SqlDataAdapter(comm3);            da2.Fill(ds,"emp");            da3.Fill(ds,"job");            da4.Fill(ds,"re");            this.treeListLookUpEdit1TreeList.DataSource = ds;            DataColumn parentColumn = ds.Tables["emp"].Columns["empNum"];            DataColumn childColumn = ds.Tables["job"].Columns["empNum"];            DataColumn secondChild = ds.Tables["re"].Columns["empNum"];            DataRelation relCustOrder;            relCustOrder = new DataRelation("对应工作", parentColumn, childColumn);            DataRelation job;            job = new DataRelation("部门调整", childColumn, secondChild);            ds.Relations.Add(relCustOrder);            ds.Relations.Add(job);            this.gridControl1.DataSource = ds.Tables["emp"];

实现效果如下：
