If you mean to say - "Disable Browser''s back button", then have a look at several Question-Answer discussions posted on CodeProject earlier on this topic.

http://www.codeproject.com/search.aspx?q=disable+back+button+%2b+asp.net&usfc=false&doctypeid=4%3b5

Response.Cache.SetCacheability(System.Web.HttpCacheability.NoCache);
        Response.AddHeader("pragma", "no-cache");
        Response.AddHeader("Cache-Control", "no-cache");
        Response.CacheControl = "no-cache";
        Response.Expires = -1;
        Response.ExpiresAbsolute = DateTime.Now.AddSeconds(-1);
        Response.Cache.SetNoStore();
 
         Page.ClientScript.RegisterStartupScript(this.GetType(), "cle", "windows.history.clear", true);

Or Use Javascript
