changing datasource

I have a listbox which has a datasource set to a List collection.

I'm trying to remove an item from the List, and then reload the listbox - expecting to see the removed item no longer present in the listbox.  Here is the code to do that:

            source.RemoveAt(0);
            listBox1.DataSource = source;
            listBox1.DisplayMember = "str";

For some reason the listbox remains the same after I execute this code.  I know the code is getting reached since if I execute it enough times, an exception is raised, since there are no more items left to remove from the List.  Thannks!

List<> does not support automatic notification of changes to bound controls. To do that you have to use a BindingList<>
When you set DataSource after the RemoveAt, nothing will change since it's the same daataSource.
This should work:

listBox1.DataSource = null;
list.RemoveAt(0);
listBox1.DataSource = list;
0
