How to pass data from index view to edit view

when click edit link in index page
it give me error
The model item passed into the dictionary is of type 'System.Data.Entity.DynamicProxies.Employee_2EF71CC17A29BA91B02BC5CDB0EE5AF82D363EEF7E174A21C9546772913AA929', but this dictionary requires a model item of type 'WebCourse.Models.Customemployee'.
