C#

//On dropdownlist1_selectedindexchanged

session.add("ddl1",dropdowlnist1.text);

//On dropdownlist2_selectedindexchanged
dropdownlist1.text= Session["ddl1"].tostring();
session.add("ddl2",dropdowlnist2.text);

//On dropdownlist3_selectedindexchanged
dropdownlist2.text= Session["ddl2"].tostring();
session.add("ddl3",dropdowlnist3.text);

//On dropdownlist4_selectedindexchanged
dropdownlist3.text= Session["ddl3"].tostring();
