X.PagedList, manual Paging and a pre-existing webapi for data only advance 1 record at a time - asp.net-core

Question

Setting up a PagedList in .netcore against a webapi that already exists.
The webapi allows me to call data using a 2 parameters, a FROM and a TAKE. I've implemented X.PagedList and it appears to work except for how it/I calculate the actual Page..
Using the code at X.PagedList, I implemented the Manual Paging. The issue is that when I click on a page number, my TAKE only takes 1 new record, as opposed to the NEXT 10.
On the first load, my api call looks like this
/api/v1/Institutions?from=0&take=10
The Page 2 call looks like
/api/v1/Institutions?from=1&take=10
Obviously the 1 should be 11 i think in this case
PagedResults Class
public class PagedResults<T> : List<T>
{
public List<T> Results { get; set; }
public string Search { get; set; }
public bool Empty { get; set; }
}
My Controller
public IActionResult PagedList(int? page)
{
ViewData["Title"] = Title;
ViewData["PageTitle"] = Title + " List";
var pageIndex = (page ?? 1) - 1;
var pageSize = 10;
//Perform API Call
var response = GetList(pageIndex, pageSize);
//Returns List<Institution>
var Institutions = response.Data;
//Returns 200, which is the total from the Headers
string total = response.Headers.Where(x => x.Name == "total").Select(x => x.Value).FirstOrDefault().ToString();
var PagedList = new StaticPagedList<Institution>(Institutions, pageIndex + 1, pageSize, Convert.ToInt32(total));
var model = new InstitutionViewModel
{
CurrentUser = CurrentUser //From BaseController
};
string view = string.Format("~/views/Portal/{0}/List.cshtml", Title);
ViewData["PagedList"] = PagedList;
return View(view, model);
}
GetList()
#region Helpers
public static IRestResponse<List<Models.Institution>> GetList(int from, int take)
{
//this create /api/v1/institutions?from=0&Take=10
string ActionPath = string.Format("Institutions");
var client = new RestClient(Connect.url);
var request = new RestRequest(ActionPath, Method.GET);
request.AddParameter("from", from, ParameterType.QueryString);
request.AddParameter("take", take, ParameterType.QueryString);
var result = client.Execute<List<Models.Institution>>(request);
return result;
}

My View
#using X.PagedList.Mvc.Core;
#using X.PagedList;
#foreach (var item in ViewBag.PagedList)
{
<tr>
<td>#item.id</td>
<td>#item.name</td>
</tr>
}
#Html.PagedListPager((IPagedList)ViewBag.PagedList, page => Url.Action("PagedList", new { page }))

Answer 1

Here is a simple workaround like below:
1.View:
#{
ViewBag.Title = "Product Listing";
var pagedList = (IPagedList)ViewBag.PageList;
}
#using X.PagedList.Mvc.Core; #*import this so we get our HTML Helper*#
#using X.PagedList; #*import this so we can cast our list to IPagedList (only necessary because ViewBag is dynamic)*#
#using X.PagedList.Mvc.Common
#using X.PagedList.Mvc.Core.Fluent
<ul>
#foreach (var name in ViewBag.PageList)
{
<li>#name</li>
}
</ul>
#Html.PagedListPager(pagedList, page => Url.Action("Index", new { page }))
2.Controller:
[HttpGet]
public IActionResult Index(int page = 1)
{
ViewBag.PageList = GetPagedNames(page);
return View();
}
protected IPagedList<string> GetPagedNames(int? page)
{
// return a 404 if user browses to before the first page
if (page.HasValue && page < 1)
return null;
// retrieve list from database/wherever
var listUnpaged = new List<string> { "a", "b", "c", "d", "e", "aa", "bb", "cc", "dd", "ee", "aaa", "bbb", "ccc" ,"ddd","eee","fff","ggg","1","s","f","sd","dsfds"};
// page the list
const int pageSize = 10;
var listPaged = listUnpaged.ToPagedList(page ?? 1, pageSize);
// return a 404 if user browses to pages beyond last page. special case first page if no items exist
if (listPaged.PageNumber != 1 && page.HasValue && page > listPaged.PageCount)
return null;
return listPaged;
}
