Get return value from SP when using LINQDatasource

Question

Hi All,

I have a Dynamic Data Website for edit, update and delete data. As we know, the dynamic data website uses LINQDatasource control for DB operations. For delete, i am using Stored Procedure instead of using default LINQ that returns a int on successfull delete. i have configured my LINQ to SQL class to use the stored procedure for delete.

My question, How to get the return value from SP when using LINQDatasource in this case.

  ALTER PROCEDURE dbo.DeleteEmployee    
        (
        @EmployeeID int
        ) 
    AS
    Delete from Employees where EmployeeID = @EmployeeID 
    RETURN 1
