Thank you for using our services.
It depends on the view you have created for your module. Do you use client side or server side binding? What is the markup and logic of binding your view? Which control you use to show the items - RadGrid or GridView?
Also do you want to filter the public control or the view in the backend. If you want to filter the public control you can pass the value of the metakey you have added to your module to FilterExpression property of the control you have. FilterExpression property is accessibe for all controls that inherits from ContentView class.
Any additional information or some screenshots will be appreciated.
