Displaying a gridview's footer with an empty (linqdatasource) datasource

The datasource of the datagrid is a LINQDataSource which relies on the value of a dropdownlist. In开发者_运维技巧 addition, I want to use the footer to insert new records - so I'd prefer not to use the empty dataset template. I am trying to find a way to always display the footer regardless if the datasource is empty or not.

EDIT: Is there a way to create an empty/invisible object of the type in the LinqDataSource?
