Try checking to see whether its null. For example:

if( Session["myName"] == null ) {
Session.Add("myName", "xyz") ;
}

Cheers,

Keep in mind that DataTables can get relatively large quite easily and
storing them in Session may be problematic under load. Make sure that you
have code that prevents large result sets from being returned from database
queries.
