Asp.net Mobile Website Query Function

I need to get the logged in users company uuid from the same datatable that you connected the membership to so that when a user logs in, the user can view his customers. Basically i need a function added to my Customers_Controller such as this: Private db As New floodpro2Entities Function IndexA(Optional ByVal id As Guid = Nothing) As ActionResult Dim Customers_1 = From m In db.v2_Customer Where m.Company_UUID = id Select m Return View([login to view URL]()) End Function Id needs to be the current users Company_Guid.
