1 下载 treeGridView.DLL库文件。

2 添加到工程中。

右键“工具箱”选择“选择项” 弹出对话框

 

选择“浏览” 选中下载还的dll库文件。完成后工具箱中会有 treeGridView控件，如下图

 

 拖动控件到windform 中

添加代码

 List<personcl> lst = new List<personcl>();
                //personcl per = new personcl { name = "cese", age = 1 };
                personcl per1 = new personcl { name = "cese", age = 2 };
                //lst.Add(per);
                lst.Add(per1);
                personcl per2 = new personcl { name = "cese", age = 3 };
                per1.subitem.Add(per2);
                personcl per3 = new personcl { name = "cese", age = 4 };
                per2.subitem.Add(per3);
                //lst.Add(new personcl { name = "wyl", age = 10, subitem = new List<personcl> { new personcl { name = "wyl", age = 11 } } });

                SetNodes(lst, treeGridView1.Nodes);

public class personcl
    {
        public string name = "1";
        public int age = 10;

        public List<personcl> subitem = new List<personcl>();
    }

　　

private void SetNodes(IEnumerable<personcl> lst, TreeGridNodeCollection nodes)
        {
           
            foreach (var item in lst)
            {
                var node = nodes.Add(item.name, item.age);
                node.ImageIndex = 0;
                SetNodes(item.subitem, node.Nodes);
            }
        }
