推荐答案

我怀疑在以编程方式添加行之后，需要将datagrid重新绑定到数据源。

I suspect that after you add the row programatically you need to rebind the datagrid to the datasource.

使用BindingList对象绑定Grid的数据源。

对BindingList对象的任何修改（添加/删除）都将导致组件模型对象刷新。因此UI元素将自动刷新而不调用后端中的任何显式方法。

Bind the datasource of the Grid using BindingList object.
Any modification to BindingList object (add/remove) will cause the component model object to refresh. So the UI element will auto refresh without calling any explicit methods in the backend.
