Reverse sort a BindingList<T>

Question

I have a custom class that inherits from BindingList(T) that I am binding to a DataGrid.

However, the DataGrid is being populated from the top down and I want it populated from the bottom up. So the bottom item is index 0 rather then the top item.

How can I change my BindingList(T) so that the DataGrid reads it in reverse?

Answer 1

This article on CodeProject.com about implementing sortable BindingList might help you.

Answer 2

Its simple, but you could also populate the binding list in reverse order (unless you have another reason for keeping the current order).

Answer 3

Why not call the ApplySort method on the IBindingList interface implementation on the BindingList<T>? You can just pass the value of ListSortDirection.Descending for the second parameter and the DataGrid should display the items in reverse order.

Answer 4

If your list is inheriting from a Collection class, you can use the Insert(0,item) method to insert to the beginning of the list. That way the newest element would appear on the top. Not sure if the BindingList supports this though.
