public PagedDataSource GetPage(int index) {

        PagedDataSource pageddatasrc = new PagedDataSource();
         //pageddatasrc.AllowCustomPaging = true;
        // pageddatasrc.AllowServerPaging = true;
         pageddatasrc.AllowPaging = true;
        pageddatasrc.DataSource = ODatasource;//where ODatasource is EntitiesCollection<GenericCustomcolection>

        pageddatasrc.PageSize = 2;

        pageddatasrc.CurrentPageIndex = index ;

PagedDataSource pageddatasrc = paginglinks.GetPage(Args.PageNo);
