Updating of BindingSource in WinForms does not update Datasource Collection

Question

I want to display a custom collection in a DataGridView in a Windows Forms app. This custom collection implements ICollection, and IEnumerable

Answer 1

You will have to manually call ResetBindings() after the data source changes if you use a container that cannot do that on your behalf.

Causes a control bound to the BindingSource to reread all the items in the list and refresh their displayed values.
