0	Correct me If I am wrong, You want to show alert message if some string are equal in Page_Load Event ? If yes, try like this if(st1.equal(st2)) ClientScript.RegisterClientScriptBlock(typeof(Page), "myscript", "alert('Equla String')", true); Let me know if you have any more issue. Thanks ! Cheers !
