推荐答案

您从来没有从电网WPF删除行。你要做的是什么：

You never have to delete the row from the WPF grid. What you have to do is:

1）定义与包含对象列表的的ObservableCollection 属性类型在网格上呈现的值。

1) define a type with a ObservableCollection property that contains a list of objects presenting the values on your grid.

2）绑定的属性网格控制。

2) Bind that property to your grid control.

3）现在从绑定集合如果添加/删除对象，相应的行会分别添加/控制的用户界面中删除。

3) now if you add/remove objects from binded collection, corresponding rows will respectively add/remove from control's ui.
