急！Aspnet

Question

 protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)
    {
        string str = GridView1.DataKeys[e.NewEditIndex].Value.ToString();
        Response.Redirect("uodatewords.aspx?FlWordsID" + str);
    }

Request.QueryString["FlWordsID"].Trim().ToString() != ""

未将对象引用设置到对象的实例。

请各位多多指教！急！
