One way to do this is to extend the ASP.NET Page class, "override" the IsPostBack property and let all your pages derive from the extended page.

public class MyPage : Page
{
    public new bool IsPostBack
    {
        get 
        { 
          return 
            Request.Form.Keys.Count > 0 &&
            Request.RequestType.Equals("POST", StringComparison.OrdinalIgnoreCase); 
         }
    }
}
