objectdatasource and delete

Question

hey all,

I'm trying to use the ObjectDataSource on my GridView but am having a problem with the delete method. I'm adding Delete parms to the ODS but when I try to delete a record it passes the entire business object instead of the int like the method is expecting. Please see link below for a better picture of what I'm getting at:
