where viewModel is of type list and I have to pass Paged list to get pagination links and for that I am using '
return View(viewModel.ToPagedList(pageNumber,pageSize));

and even after that i am using the below
<%: Html.PagedListPager((IPagedList)Model, page => Url.Action("Index",
new { page}),PagedListRenderOptions.PageNumbersOnly)%>
