I have a private instance of a collection of business objects on a form. On form load, I fill the collection with data and bind it to a treeview. In reaction to user input elsewhere on the form, I add and remove items from the collection. At that point I need to refresh the binding of the TreeView. I tried resetting the DataSource property and I've tried the Refresh and Update methods, but nothing I do makes the TreeView display the new data.
How do I do this?
