Assuming you are using DataTable to hold the values, pleasee see the following solution :

C#

DataTable dt = Session["dbValues"] as DataTable;
DataRow dr = dt.NewRow();
// add data to the new row
// i.e. dr["name"]="something";

// add this row to DT now
dt.Rows.Add(dr);

// assign this modified Datatable back to Session
Session["dbValues"] = dt;

Similarly, You can type cast any object that you are holding in Session and manipulate the object and re-assign it to same session variable.
