Winfrom中treeView获取子节点

1.动态获取子节点后放入groupControl2表中

  private void LoadUnInspectionDJ()// treeView1

        {

 

            treeView1.Nodes.Clear();

            LTron.Framework.SystemService.Proxy.SYS_COMMON_PROXY COM_PROXY = new     LTron.Framework.SystemService.Proxy.SYS_COMMON_PROXY(); --new一个新表

            DataTable RES = COM_PROXY.ExecuteQuerySql("SELECT MATERIAL_NO,MATERIAL_SPEC FROM MMD_MATERIAL_MASTER WITH(NOLOCK) WHERE PART_TYPE IN ('FG','ASSEMBLY')");

            COM_PROXY.CloseChannel();--查询sql语句

 

            for (int i = 0; i < RES.Rows.Count; i++)  --循环取值

            {

                //  treeView1.Nodes.Add("item", RES.Rows[i]["MATERIAL_NO"].ToString());

                TreeNode node = new TreeNode();

                node.Text = RES.Rows[i]["MATERIAL_NO"].ToString();

                node.Name = "MATERIAL_NO";

                node.ImageIndex = imageList1.Images.IndexOfKey("item");

                node.SelectedImageIndex = imageList1.Images.IndexOfKey("item");

                treeView1.Nodes.Insert(0, node);

                node.Nodes.Add("MATERIAL_DESC", RES.Rows[i]["MATERIAL_SPEC"].ToString());

 

            }

 

            groupControl2.Text = "物料列表:" + treeView1.Nodes.Count.ToString();

        }
