利用递归方法将UltraWebTree和数据表绑定

private void LoadRootNodes()
{
          UltraWebTree1.ClearAll();//清空显示
   dvR.RowFilter="Class=1";//用到datareader的过滤功能
    foreach(DataRowView dr in dvR)
    {
 string McR=dr["Name"].ToString();
 int IDR=Convert.ToInt32(dr["ID"].ToString());
        Infragistics.WebUI.UltraWebNavigator.Node  //定义节点类型                           

 RootNode=UltraWebTree1.Nodes.Add(McR,IDR);     //在指定的节点上添加节点     
       LoadChildNodes(RootNode,IDR);
     }
}

private void LoadChildNodes(Infragistics.WebUI.UltraWebNavigator.Node ParentNode, int

ParentNodeId)//需要得到节点类型和id值，一一对应
{
            DataView dvC=new DataView();
            dvC.Table=ds.Tables["Bumen"];
            dvC.RowFilter="Former="+ParentNodeId;
   
 foreach(DataRowView drc in dvC)
 {
 string McC=drc["Name"].ToString();
 int IDC=Convert.ToInt32(drc["ID"].ToString());
     Infragistics.WebUI.UltraWebNavigator.Node ChildNode

=ParentNode.Nodes.Add(McC,IDC);
 LoadChildNodes(ChildNode,IDC);//递归调用
        }
}
