Hola en realidad veo que solo necesito la direccion url de las paginas de este gridview para remplazalo en estre script javascript
<script type="text/javascript">
var pagina = '('http:\\www.google.com')';
var segundos = 500;
function redireccion() {
document.location.href=pagina;
}
setTimeout("redireccion()",segundos);
este codigo me sale ne el javascript en el gridview:
<td><span>1</span></td><td><a href="javascript
:__doPostBack('GridView1','Page$2' )" style="color:White;">2</a></td><td><a href="javascript
:__doPostBack('GridView1','Page$3' )" style="color:White;">3</a></td><td><a href="javascript
:__doPostBack('GridView1','Page$4' )" style="color:White;">4</a></td><td><a href="javascript
:__doPostBack('GridView1','Page$5' )" style="color:White;">5</a></td><td><a href="javascript
:__doPostBack('GridView1','Page$6' )" style="color:White;">6</a></td><td><a href="javascript
:__doPostBack('GridView1','Page$7' )" style="color:White;">7</a></td><td><a href="javascript
:__doPostBack('GridView1','Page$8' )" style="color:White;">8</a></td><td><a href="javascript
