[2005] Passing a value to a sqlDataSource

[cometburn007]

Need help here Badly... i created a gridview inside a gridview (this is to view the extended details of a certain person because of too many fields, i decided to do this.) which is binded to a sqldatasource. i can now get the value of the PersonID and store it to a session variable named Session("PersonID"). Now, my Problem is, how am i going to pass the Session variable to the sqlDataSource when the sqlDatasource and the Gridview is Inside a Gridview?
