推荐答案

您可以通过两种方式处理此问题-它们都涉及以包含DGV的形式进行的工作.
第一种是以表单的形式创建属性或方法，该属性或方法被赋予要删除的行的标识.然后，通过引用子窗体创建时的实例来调用它.

另一个是以孩子所订阅的父表单形式提供一个事件.父级通知事件(可能使用自定义EventArgs传递要删除的记录的标识)，然后子级处理该事件，删除记录.

就个人而言，我会选择第二个选项.

There are two way you can handle this - and they both involve the work being done in the form containing the DGV.
The first is to create a property or method in the form, which is given the identity of the row to delete. You then call this by reference to the instance of the child form from when it was created.

The other is to provide an event in the parent form to which the child subscribes. The parent signals the event (possibly with a custom EventArgs to pass through the identity of the records to remove) and teh child handles it, deleting the records.

Personally, I would go with the second option.
