There is no such thing as
DeleteOnSubmitnorDeleteAllOnSubmitin ASP.NET MVC, so I’ll assume that you mean the methods in LINQ to SQL tables. (Correct me if not.)Basically, you use
DeleteOnSubmitto delete a single row from a table, by specifying a single entity which maps to the row you want to delete.DeleteAllOnSubmitis there for you if you want to delete multiple rows from a table, by specifying multiple entities, more correctly anIEnumerable<>of those, which means that you can specify them in more or less any collection. (List<T>,Collection<T>, and many more.)
