DataGridView with LINQ fast autosave changes

Question

I'm use DataGridView with LINQ BindingSource. And I need autosave changes after adding, editing or deleting rows by:

dataContext.SubmitChanges();

Now I'm use AddedRow, DeletedRow, ValueChanged events, but when user delete 1000 rows, this causes 1000 calls of "dataContext.SubmitChanges();" and this is very slow.

How i can call "dataContext.SubmitChanges();" one time after adding, deleting or editing all rows?

看起来您可以使用bindingSource的List_Changed事件，如此处所述： 使用bindingsource拥有busniess对象
