title: VB.NET How iterate through a BindingSource
body: <p>I have a BindingSource bound to a DataTable.</p>
  
  <p>I use the BS Filter and would like to iterate the filtered dataset of the DataTable using the Bindingsource.</p>
  
  <p>I know I can do a MoveFirst and the MoveNext and each time using the BS.Position get the correct row in the underlying DataTable.
  But how do I know when the sets ends? I'm sure there must be such a property, but what is it? </p>
