Problem With Deletecomand Attribute Of Asp:sqldatasource

Greetings everyone. I'm trying to set up a GridView that makes use of an SQL Datasource. All commands (update,select,delete) are set within the tag's attributes but when i hit the Delete Trigger it returns that the id variable is undeclared.

<asp:SqlDataSource
                   ID="KevinDataSource"
                   ConnectionString="Server=overmind;Database=kevin_bonis;User=sa;Password="
                    SelectCommand="SELECT * FROM Accesorii"
                    UpdateCommand="Update Accesorii SET nume_accesoriu=@nume_accesoriu,
                                                        articol=@articol,
                                                        cantitate=@cantitate,
                                                        trimis_bolla=@trimis_bolla,
                                                        bolla=@bolla,
                                                        data_trimitere=@data_trimitere,
                                                        intors=@intors,
                                                        data_intoarcere=@data_intoarcere WHERE id=@id"
                    DeleteCommand="DELETE FROM Accesorii WHERE id = @id"
                    runat="server" />

What could be the problem with this? I'll appreciate any help i can get.
Thanks alot, Allyrion
