MVC Grid Wrapper with Popup Editing and Dropdown

[Paul]

Could someone point me to a working example of how to implement a Kendo MVC Wrapper Grid that has Add and Edit popup.
In the popup editor to Edit: I'd like to be able to show the Product.Name, but change only the ProductType and ProductCategory.
In the popup editor to Add, I'd like to be able to select the Product, ProductType, and ProductCategory.
e.g.

ProductCategory:
ID
Name

ProductType:
ID
Name

Product:
ID
Name
ProductType
ProductCategory

Thanks
