Access a view from C#

How do I access data bound properties inside the C# editor? There is a view called RuleMtlView with a property of MtlSeq. I would normally access this like this ‘{RuleMtlView.MtlSeq}’ as seen/used under “Debug” below. any ideas?

I found this post where a data view is accessed. Maybe I am missing a reference?

var edvUD103A= oTrans.Factory(“UD103A”); //Get a hold of the existing view
