在树视图中的每个父节点之后添加按钮或链接

Question

我有一个树视图，它正确地填充父，子和大子节点。

-Root 1
  |
  |___________ Child 1
  |___________ Child 2
  |___________ Child 3

- Root 2
  |___________ Child A
  |___________ Child B
  |               |___________ Grand Child 1
  |               |___________ Grand Child 2
  |
  |___________ Child C

现在我想在每个父节点之后创建一个Create按钮/链接，以创建一个新的子元素或者子元素。

-Root 1
  |___ **Create New Child**
  |
  |___________ Child 1
  |___________ Child 2
  |___________ Child 3

- Root 2
  |____ **Create New Child**
  |__________ Child A
  |___________ Child B
  |               |__ **Create New Child**
  |               |________ Grand Child 1
  |               |___________ Grand Child 2
  |
  |___________ Child C

因此，当我点击Create New Child时，它会打开一个空白表单，我可以在其中填写信息并创建一个新孩子，现在我可以通过点击任何节点来编辑节点信息。

这是我创建节点的代码。

 #region ROOT NODE

        DataTable dtInstitute = dsResult.Tables[0]; //dsResult contains two columns refValues, refGroupId , I have separate code for that

        List<Button> buttons = new List<Button>();

        foreach (DataRow row in dtInstitute.Rows)
        {
            TreeNode child = new TreeNode
            {
                Text = row["refValues"].ToString(),
                Value = row["refGroupId"].ToString()
            };

            AddChild(child);
            treeCatalogManager.Nodes.Add(child);
        }

        treeCatalogManager.CollapseAll();

 #endregion


  private void AddChild(TreeNode child)
    {
        #region ADD CHILD

        DataTable dtChild = dsChildResult.Tables[0];    //dsChildResult contains two columns refValues, refGroupId , I have separate code for that and able to populate here        

        foreach (DataRow row in dtChild.Rows)
        {
            TreeNode nChild = new TreeNode
            {
                Text = row["refValues"].ToString(),
                Value = row["refGroupId"].ToString()
            };

            AddChild(nChild);
            child.ChildNodes.Add(nChild);

        }

        #endregion
    }
