How to Refresh page without postback???

Hi,

 I've redered the GridView using the CallBackFunction in the my ASP.Net page using C#.

There is a template Field in the Gridview. Now, when i'm clicking on the link button instead of giving the udpated values from the GridView it is reflecting the old values are filled on the Page_Load.

I think this happened because the page hasn't postback. kindly suggest how can i refresh the complete page without postback.

Any suggestion or Ideas ??

Thanks
