// You can do it this way
        // take one viewState and save querystring value into it
        // first time, value is set into viewstate.
        if (ViewState["key"] == null)
        {
            ViewState["key"] = Request.QueryString["myID"];
        }
        // other condition to check that the value of viewstate and querystring is same
        if (ViewState["key"].ToString() != Request.QueryString["myID"])
        {
            // if it is not same then redirect user to another page
            // redirect user here
