How can I pass the current user's UserID to a SQL query via an ObjectDataSource?  I have the TableAdapter set up to query the sitesql database depending on the current user's UserID.  I'm having a brain block on how to pass the UserID to the DataSource.  Is it a Session or Profile or Cookie, etc.?  What would that codeline look like for the appropriate parameter?

I know this is a simple thing, but I'm having a brain block on what the actual code would look like.

Thanks for any help,
