I'm trying to get paging to work with multiple searches and sort orders. When I do a search the first page returned is the correct page of the result set but when I use the pagination buttons to select the next page my search no longer factors in and I get all results.
My controller looks like this:
public ActionResult Index(string sortOrder, string searchString, string currentFilter, int? page, string Site, string Name, string Acct, string City, string State, string Address, string Status, string Type)
{
ViewBag.CurrentSort = sortOrder;
ViewBag.NameSortParm = String.IsNullOrEmpty(sortOrder) ? "name_desc" : "";
ViewBag.AddressSortParm = sortOrder == "Address" ? "addr_desc" : "Address";
ViewBag.SiteSortParm = sortOrder == "Site" ? "site_desc" : "Site";
ViewBag.CitySortParm = sortOrder == "City" ? "city_desc" : "City";
ViewBag.StateSortParm = sortOrder == "State" ? "state_desc" : "State";
if (searchString != null || Site != null || Name != null || Acct != null || City != null || State != null || Address != null)
{
page = 1;
}
else
{
searchString = currentFilter;
}
ViewBag.CurrentFilter = searchString;
var geocodes = from s in db.CFN_Geocodes select s;
if (!String.IsNullOrEmpty(Name))
{
geocodes = geocodes.Where(s => s.NAME.Contains(Name));
}
if (!String.IsNullOrEmpty(Site))
{
geocodes = geocodes.Where(s => s.CFN_SITE.Contains(Site));
}
if (!String.IsNullOrEmpty(Address))
{
geocodes = geocodes.Where(s => s.STREET1.Contains(Address));
}
if (!String.IsNullOrEmpty(City))
{
geocodes = geocodes.Where(s => s.CITY.Contains(City));
}
if (!String.IsNullOrEmpty(State))
{
geocodes = geocodes.Where(s => s.STATE_CODE.Contains(State));
}
if (!String.IsNullOrEmpty(Acct))
{
geocodes = geocodes.Where(s => s.AccountNumber.Contains(Acct));
}
if (!String.IsNullOrEmpty(Status))
{
geocodes = geocodes.Where(s => s.Status.ToString().Contains(Status));
}
if (!String.IsNullOrEmpty(Type))
{
geocodes = geocodes.Where(s => s.SiteType.Contains(Type));
}
switch (sortOrder)
{
case "name_desc":
geocodes = geocodes.OrderByDescending(s => s.NAME);
break;
case "Address":
geocodes = geocodes.OrderBy(s => s.STREET1);
break;
case "addr_desc":
geocodes = geocodes.OrderByDescending(s => s.STREET1);
break;
case "Site":
geocodes = geocodes.OrderBy(s => s.CFN_SITE);
break;
case "site_desc":
geocodes = geocodes.OrderByDescending(s => s.CFN_SITE);
break;
case "City":
geocodes = geocodes.OrderBy(s => s.CITY);
break;
case "city_desc":
geocodes = geocodes.OrderByDescending(s => s.CITY);
break;
case "State":
geocodes = geocodes.OrderBy(s => s.STATE_CODE);
break;
case "state_desc":
geocodes = geocodes.OrderByDescending(s => s.STATE_CODE);
break;
default:
geocodes = geocodes.OrderBy(s => s.NAME);
break;
}
int pageSize = 20;
int pageNumber = (page ?? 1);
return View(geocodes.ToPagedList(pageNumber, pageSize));
}
And my view looks like this:
#model PagedList.IPagedList<Intranet.Models.CardlockSiteMgr.CFN_Geocodes>
#using PagedList.Mvc
<link href="~/Content/PagedList.css" rel="stylesheet" type="text/css" />

Any ideas on what I'm doing wrong here?
I ended up using session variables, even though it's not the best method.
if (Status != null)
{
System.Web.HttpContext.Current.Session["Status"] = Status;
}
if (System.Web.HttpContext.Current.Session["Status"] != null)
{
Status = System.Web.HttpContext.Current.Session["Status"].ToString();
}
if (Type != null)
{
System.Web.HttpContext.Current.Session["Type"] = Type;
}
if (System.Web.HttpContext.Current.Session["Type"] != null)
{
Type = System.Web.HttpContext.Current.Session["Type"].ToString();
}
if (Name != null)
{
System.Web.HttpContext.Current.Session["Name"] = Name;
}
if (System.Web.HttpContext.Current.Session["Name"] != null)
{
Name = System.Web.HttpContext.Current.Session["Name"].ToString();
}
if (Site != null)
{
System.Web.HttpContext.Current.Session["Site"] = Site;
}
if (System.Web.HttpContext.Current.Session["Site"] != null)
{
Site = System.Web.HttpContext.Current.Session["Site"].ToString();
}
if (Acct != null)
{
System.Web.HttpContext.Current.Session["Acct"] = Acct;
}
if (System.Web.HttpContext.Current.Session["Acct"] != null)
{
Acct = System.Web.HttpContext.Current.Session["Acct"].ToString();
}
if (City != null)
{
System.Web.HttpContext.Current.Session["City"] = City;
}
if (System.Web.HttpContext.Current.Session["City"] != null)
{
City = System.Web.HttpContext.Current.Session["City"].ToString();
}
if (State != null)
{
System.Web.HttpContext.Current.Session["State"] = State;

If someone can help, I would be very thankful.
I'm using C# in VS 2017 for an ASP.net Application.
In a razor view, I have this code:
<div class="text-center" >
<ul class="pagination">
#for (var i = 1; i <= ViewBag.SearchMetaData.SearchNumberOfPages; i++)
{
if (ViewBag.SearchMetaData.SearchCurrentPage == #i)
{
<li class="active"> #Html.ActionLink(#i.ToString(), "CI_SequenceBlocks_Pager_Form_Handler", new { id = #i, value = ViewBag.SearchMetaData.SearchString, inInstitutionProgramID = ViewData["SelectedInstitutionProgram"].ToString() },null)</li>
}
else
{
<li> #Html.ActionLink(#i.ToString(), "CI_SequenceBlocks_Pager_Form_Handler", "Home", new { id = #i, value = ViewBag.SearchMetaData.SearchString, inInstitutionProgramID = ViewData["SelectedInstitutionProgram"].ToString() },null)</li>
}
}
</ul>
</div>
}
It works great on my development machine. The actionlinks never fail.
However, when I publish to the server, I can click on the links 3 or 4 times and they work. After the 4th time, it is like the variables are forgotten. When I view the page source the links appear to correct. It seems to me something on the server is being reset. Does anyone have any ideas?
Here is more code:

____________NEW UPDATE____________
Found the issue:
I changed RedirectToActionPermanent to RedirectToAction. No more problems!
Thanks,
James
I have 2 actions methods, one them works as "Get" method but shows a list and just gets 1 value from user. The other updates the database with the value received. However, it seems like I'm not passing this value to the 2nd controller as I see it to be null when debugging code.
Can anyone help find my mistake ?
The action methods :
[AllowAnonymous]
public ActionResult AvaliaAluno()
{
var user = User.Identity.GetUserId();
if (User.IsInRole("Docentes") || User.IsInRole("Comissao"))
{
Docente d = db.Docentes.SingleOrDefault(x => x.UserId == user);
var vm = new ViewModels
{
Propostas = db.Propostas.Where(x => x.DocenteId == d.DocenteId).ToList(),
Alunos = db.Alunos.ToList(),
Candidaturas = db.Candidaturas.ToList()
};
return View(vm);
}
if (User.IsInRole("Empresas"))
{
Empresa d = db.Empresas.SingleOrDefault(x => x.UserId == user);
var vm = new ViewModels
{
Propostas = db.Propostas.Where(x => x.EmpresaId == d.EmpresaId).ToList(),
Alunos = db.Alunos.ToList(),
Candidaturas = db.Candidaturas.ToList()
};
return View(vm);
}
return View();
}
[AllowAnonymous]
public ActionResult ConfirmaAvaliacao(int id, decimal? avaliacao)
{
Candidatura c = db.Candidaturas.SingleOrDefault(x => x.CandidaturaId == id);
Proposta p = db.Propostas.SingleOrDefault(x => x.PropostaId == c.PropostaId);
if (User.IsInRole("Docentes") || User.IsInRole("Comissao"))
{
p.AvaliacaoDocenteAluno = avaliacao;
return RedirectToAction("AvaliaAluno");
}
if (User.IsInRole("Empresas"))
{
p.AvaliacaoEmpresaALuno = avaliacao;
return RedirectToAction("AvaliaAluno");
}
return RedirectToAction("Index", "Home");
}
and the view:
#model DEIS_ISEC.Models.ViewModels
<h3>Alunos Orientados por si</h3>
<table class="table">
<tr>
<th>

<th>

</tr>
#foreach (var item in Model.Propostas)
{
<tr>
#foreach (var c in Model.Candidaturas)
{
if (c.PropostaId == item.PropostaId)
{
foreach (var a in Model.Alunos)
{
if (a.AlunoId == c.AlunoId)
{
<td>
#Html.DisplayFor(modelItem => a.Nome) #Html.DisplayFor(modelItem => a.Apelido)

}
}
}
}
<td>
#Html.DisplayFor(modelItem => item.Titulo)

<td>
#Html.DisplayFor(modelItem => item.Ramo)
</td>
<td>
#Html.DisplayFor(modelItem => item.DataInicio)

#Html.EditorFor(modelItem => item.AvaliacaoDocenteAluno, new { htmlAttributes = new { #class = "form-control", #style = "width:50% !important; min-width:50px;" } })
#Html.ValidationMessageFor(modelItem => item.AvaliacaoDocenteAluno, "", new { #class = "text-danger" })
</td>
<td>
#Html.ActionLink("Guardar", "ConfirmaAvaliacao", new { id = item.CandidaturaId, avaliacao = item.AvaliacaoDocenteAluno }, new { #class = "btn btn-info btn-md" })
</td>
</tr>
}
I believe that the moment when i get the input from user here :
#Html.EditorFor(modelItem => item.AvaliacaoDocenteAluno, new { htmlAttributes = new { #class = "form-control", #style = "width:50% !important; min-width:50px;" } })
#Html.ValidationMessageFor(modelItem => item.AvaliacaoDocenteAluno, "", new { #class = "text-danger" })
something unexpected happens.
I suggest you take a look at ASP.NET MVC 4 Helpers, Forms and Validation > Exercise 3: Creating the Edit View on how to implement an Edit mechanism with ASP.Net MVC.
In general, I recommend you go over the complete example in the link, as it covers many of the subjects required for building an ASP.Net MVC application.
Hope it helps!

Greetings I have developed an ASP.NET MVC 5 application. I'm using pagination, it works but when I want to call a query that I wrote I get the error:
Additional information: Object reference not set to an instance of an object.
I think its a problem on routing but I can't figure it out.
Here is my controller:
public ActionResult Index(string searchString, int? omonimipage, int? id, int? courseID, int? idcom, int? elencoimo, int? elecoimobi, int? elencoinsta, int? page)
{
int elencoomoninumber = (omonimipage ?? 1);
var viewmodel = new mainview();
viewmodel.elencoomonimi = db.ElencoOmonimis
.Include(s => s.ElencoProvinces)
.Include(s => s.ElencoProvinces.Select(r => r.ElencoImmobiliPerDiritti_E_Quote))
.Include(s => s.ElencoProvinces.Select(r => r.ElencoComunis))
.Include(s => s.ElencoProvinces.Select(r => r.ElencoImmobiliPerDiritti_E_Quote.Select(q => q.ElencoIntestatis)))
.OrderBy(i => i.Id).ToPagedList(elencoomoninumber,6);
if (id != null)
{
ViewBag.elencoprovinceID = id.Value;
viewmodel.elencoprovince = viewmodel.elencoomonimi.Where(
i => i.Id == id.Value).SingleOrDefault().ElencoProvinces;
}
if (idcom != null)
{
ViewBag.ElencoImmobiliperID = idcom.Value;
viewmodel.elencointestati = viewmodel.elencoimobili.Where(
r => r.Id == idcom.Value).Single().ElencoIntestatis;
}
if (elencoimo != null)
{
ViewBag.elecomuniID = elencoimo.Value;
viewmodel.elencocomuni = viewmodel.elencoprovince.Where(
r => r.Id == elencoimo.Value).Single().ElencoComunis;
}
if (elecoimobi != null)
{
ViewBag.ElencoimobID = elecoimobi.Value;
viewmodel.elencoimobili = viewmodel.elencoprovince.Where(
q => q.Id == elecoimobi.Value).Single().ElencoImmobiliPerDiritti_E_Quote;
}
if (elencoinsta != null)
{
ViewBag.ElencoInstatiID = elencoinsta.Value;
viewmodel.elencointestati = viewmodel.elencointestati = db.ElencoImmobiliPerDiritti_E_Quote.Where(
e => e.Id == elencoinsta.Value).Single(i =>i.Id == elencoinsta.Value).ElencoIntestatis;
}
return View(viewmodel);
}
and here is my view:

Thank you.
I am displaying page links with the help of PagedList in ASP.net MVC. But the issue is if there are 100 pages then all links show at the same time but i want to show 10 links at a time. How can it be achieved. Please Help. Thanks.. Below is the working Code.
Index.cshtml
#model PagedList.IPagedList<MvcPagingList.Models.Employee>
#{
ViewBag.Title = "Employees";
}

I faced the same issue & solved it by studying the following Code :-

You will have to use webgrid for this.
