ProgressiveLoading<TKey>(Expression<Func<T,TKey>>,Boolean,Int32) Method

Specifies that the client view loading is performed not in a single trip to the server but in multiple batches, each loading a page of a limited size so the user sees the result and can interact with it before all pages are loaded.

C#
