推荐答案

DataGridView中的控件不能绑定子自动对象。

DataGridView-controls can not bind child objects automatically.

如果您正在使用的Win-形式的工作，我的建议是创建两个对话框窗口。

If you are working with Win-forms, my suggestion would be to create two Dialog windows.

一个是父对象（带DGV）和另一为儿童的对象（具有DGV）。

One is for parent-objects(with a DGV) and another is for child-objects(with a DGV).

当用户打开父窗口，父对象会被加载逐行在DGV

When the user opens the parent window, parent objects would be loaded row-wise in the DGV.

然后，如果用户双击父窗口上的行，子窗口将被示出和该父的子对象将在DGV对孩子进行填充窗口。

Then if the user double-clicks a row on the parent-window, the child-window would be shown up and the child objects of that parent would be populated on the DGV on the child window.

在这种方式你可以保持干净的东西，不管父子关系有多深。此外，添加，编辑，删除等操作会更清洁

In this way you can keep things clean no matter how deep the parent-child relationships go. Moreover, add, edit, delete, etc. operations would be much cleaner.

您也可以使用一些第三方控件一样，的 HierarchicalDataGridView 。

You can also use some third-party controls like, HierarchicalDataGridView.
