As said by sumit you can use scripting language techniques to display the alert box
on a particular event

If you dont want to implement scripting then you need to write your own custom class in
order to implement that functionality

If you want you can post your reply to me so that i can post the custom class for you

You can use this code

  ClientScript.RegisterClientScriptBlock(typeof(Page), "test", "<script language='javascript'>alert('Your message'); </script>");
