Unable to cast object of type 'system.data.datatable' to type 'lInqobj.tbl1'

property.setAgent(((Agent)Session[FormContract.AGENT]).agent_id.ToString());

Unable to cast object of type 'system.data.datatable' to type 'lInqobj.Agent'

Clearly the object found at Session[FormContract.AGENT] is not actually an Agent, but a DataTable, so it cannot be cast to an Agent. Try figuring out what is putting that value there, and why it's putting a DataTable there rather than an Agent.
