人員選擇分類樹的實現

 詳細代碼如下：

 

      private void initTree()
        {
         ///初始化可選擇的人員
            this.treeView1.Nodes.Clear();
         TreeNode  RootNode=null,ZMCNode=null,RYNode=null;
         RootNode = new TreeNode();
         RootNode.Tag = "-1";
         RootNode.Text = "所有經辦人員";
       
             公用類.Model.人員基本資料  ry=new  公用類.Model.人員基本資料();
             System.Data.DataTable table = ry.GetTable("RYLB=1");
             if (table != null)
             {
                  string[] ZB = new string[1];
                  ZB[0] = "RYZB";
                  System.Data.DataTable newTable = table.DefaultView.ToTable(true, ZB);
                 foreach (DataRow ZRow in newTable.Rows)
                 {
                     ZMCNode = new TreeNode();
                     ZMCNode.Text = ZRow["RYZB"].ToString(); ;
                     ZMCNode.Tag = "-2";

                     System.Data.DataRow[] RYRow = table.Select("RYZB='" + ZRow["RYZB"].ToString() + "'", "");

                     foreach (DataRow Row in RYRow)
                     {
                         RYNode = new TreeNode();
                         RYNode.Text = Row["RYXM"].ToString();
                         RYNode.Tag = Row["RYBH"].ToString();
                         ZMCNode.Nodes.Add(RYNood);

                     }
                     RootNode.Nodes.Add(ZMCNood);
                 }
                
             }
             this.treeView1.Nodes.Add(RootNood);
        }

 

效果如下：
