Modificar html en Page_Load

[Stream]

Código:

   Private Sub Page_PreRender(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.PreRender
        Response.Write("<script languaje='javascript'> window.document.title='Este es tu titulo'; </script>")
    End Sub

Yo usaria el evento Render de la pagina...
