public virtual void Delete()

Public Overridable Sub Delete

Deleting a view item is an update operation on the view. As any other update operation performed directly on the view (as opposed to on the base data collection on which that view depends, see AsUpdatable<(Of <<'(T>)>>)(View<(Of <<'(T>)>>))), it is allowed only if the view is not read-only (see IsReadOnly), and it results in updating (in this case, deleting an item from) one of the view's base data collections.
