PagedList error when passing Data with Viewmodel
Hi I was wondering if anyone con shed some light with a problem that I´m experiencing when implementing pagedlist code (https://github.com/TroyGoode/PagedList) in my asp.net mvc3 website. This are the details of what I´m trying to do:
I created a Viemodel with this details:
public class ProductViewM开发者_如何学GoodelList
{
public List<Product> ProductBrowse { get; set; }
public int NumberOfProducts { get; set; }
public List<Category> CategoryModel { get; set; }
}
Then a Controller holding the information that I want to pass to the view:
public ActionResult List(int categoryid, int? page)
{
const int defaultPageSize = 20;
int currentPageIndex = page.HasValue ? page.Value - 1 : 0;
var categoryModel = db.Category.Include("Product").Single(c => c.CategoryId == categoryid);
var paginatedmodel = categoryModel.Product.ToPagedList(currentPageIndex, defaultPageSize);
var viewModel = new ProductViewModelList
{
ProductBrowse = paginatedmodel.ToList(),
NumberOfProducts = categoryModel.Product.Count()
};
return View(viewModel);
Finally the View that starts with:
@inherits System.Web.Mvc.WebViewPage<IPagedList<Social.ViewModels.ProductViewModelList>>
@using Social.Helpers;
@using System.Web.Mvc.Html
and create a foreach with pager in this way:
@foreach (var item in Model)
{
<div class="result">
<div class="info_result"><h2><a>@Html.ActionLink(Html.TruncateText(item.Title, 25), "Details", new { id = item.ProductId })</a></h2><p><a>@Html.ActionLink(Html.TruncateText(item.Description, 180), "Details", new { id = item.ProductId })</a></p<a>@String.Format("{0:dddd, MMMM d, yyyy}", item.CreatedOn)</a></div>
<div class="paginacion">@Html.Pager(Model.PageSize, Model.PageNumber, Model.TotalItemCount)</div>
Information: 1- Im using
@inherits System.Web.Mvc.WebViewPage<IPagedList<Social.ViewModels.ProductViewModelList>>
because I need to pass information from the IPagedList and from the ProductViewModelList to the View.
2- If I pass inherits like <IPagedList<Social.ViewModels.ProductViewModelList>
I received complete intellisense for IPagedList properties but for Viewmodels NumberofProducts, ProductBrowse, CategoryModel I only receive their names but not ther properties like ProductBrowse.ProductId as an example.
3- I would like to display a URL of the type: http://www.domain.com/Controller/List?categoryId=2&page=1
4- I dont know what I have to do in order to include object values for
Html.Pager(Model.PageSize, Model.PageNumber, Model.TotalItemCount, ObjectValues for categoryId=2)
Sorry if this is a mess to understand, I tried my best in order to explain. thanks in advance.
Instead of:
@inherits System.Web.Mvc.WebViewPage<IPagedList<Social.ViewModels.ProductViewModelList>>
try:
@model IPagedList<Social.ViewModels.ProductViewModelList>
Also instead of writing foreach loops in your views you could use a display template. So in your view:
<div class="result">
@Html.DisplayForModel()
</div>
<div class="paginacion">
@Html.Pager(Model.PageSize, Model.PageNumber, Model.TotalItemCount)
</div>
and inside ~/Views/Home/DisplayTemplates/ProductViewModelList.cshtml
@model Social.ViewModels.ProductViewModelList
<div class="info_result">
<h2>
@Html.ActionLink(
Html.TruncateText(Model.Title, 25),
"Details",
new { id = Model.ProductId }
)
</h2>
<p>
@Html.ActionLink(
Html.TruncateText(Model.Description, 180),
"Details",
new { id = item.ProductId }
)
</p>
<!-- I've modified this to use a display template instead of String.Format
Now you only need to decorate your view model property with the DisplayFormat attribute like this:
[DisplayFormat(DataFormatString = "{0:dddd, MMMM d, yyyy}")]
public DateTime? CreatedOn { get; set; }
-->
@Html.DisplayFor(x => x.CreatedOn)
</div>
You can try another library PagedListExt. It can be installed by nuget-pakage
