In my opinion, I don't think anyone can argue that Pure Components has produced some really great components and controls. And now we can add another one to the list:- The Entry Set Component Extender Providers.
There are three of them in the set.
The Visual Extender (tm) (My Favorite)
The Validation Extender (tm)
The Item Binding Extender (tm).
All of them are packed with feature rich design time and runtime support.
