I am using Pagedlist for Pagination in my MVC project. Pagination is working for most of the cases without ViewModels.
But when I use a ViewModel PagedList generating Pagination links but without any parameter value to querystring page.
Here is my ViewModel
public class SearchResult
{
public int ItemID { get; set; }
public string ItemTitle { get; set; }
public int? AuthorID { get; set; }
public string AuthorName { get; set; }
public int? IssueDate { get; set; }
}
And ActionResult Method
public ActionResult Date(int? page)
{
try
{
string query;
if (Request.RequestContext.RouteData.Values["query"] != null)
{
using (dreposEntities db = new dreposEntities())
{
query = Request.RequestContext.RouteData.Values["query"].ToString();
int issueYear = int.Parse(query);
ViewBag.Query = issueYear;
var dateFilter = db.itemstreams.Where(q => q.issuedate == issueYear).ToList();
List<SearchResult> resultList = new List<SearchResult>();
if (dateFilter.Any())
{
foreach (var c in dateFilter)
{
SearchResult obj = new SearchResult
{
ItemID = c.id,
ItemTitle = c.title,
IssueDate = c.issuedate,
};
resultList.Add(obj);
}
}
ViewBag.SearchQuery = query;
return View(resultList.OrderBy(d=>d.IssueDate).ToPagedList(page ?? 1, 10));
}
}
else
{
using (dreposEntities db = new dreposEntities())
{
List<SearchResult> resultList = new List<SearchResult>();
var files = db.itemstreams.Where(s=>s.status==1).ToList();
if (files.Any())
{
foreach (var f in files)
{
SearchResult obj = new SearchResult
{
ItemID = f.id,
ItemTitle = f.title,
IssueDate = f.issuedate,
};
resultList.Add(obj);
}
}
return View(resultList.OrderBy(d=>d.IssueDate).ToPagedList(page ?? 1, 10));
}
}
}
catch (Exception e)
{
return View();
}
}
What above code is showing in View is attached in below email
And in View/Razor
<div class="pull-right">
#Html.PagedListPager(Model, page => Url.Action("Date", new { page }), new PagedListRenderOptions() { Display = PagedListDisplayMode.IfNeeded })
</div>

I am new to C# and OOP, in general, I've kinda hit a wall I am reading in this CSV using the CSV Helper package, but there are some unwanted rows, etc so I have cleaned it up by iterating over "records" and creating a new class LineItems.
But Now I appear to be a bit stuck. I know void doesn't return anything and is a bit of a placeholder. But How can I access all the instances of LineItems outside of this function?
public void getMapper()
{
using (var StreamReader = new StreamReader(#"D:\Data\Projects\dictUnitMapper.csv"))
{
using (var CsvReader = new CsvReader(StreamReader, CultureInfo.InvariantCulture))
{
var records = CsvReader.GetRecords<varMapper>().ToList();
foreach (var item in records)
{
if (item.name != "#N/A" && item.priority != 0)
{
LineItems lineItem = new LineItems();
lineItem.variableName = item.Items;
lineItem.variableUnit = item.Unit;
lineItem.variableGrowthCheck = item.growth;
lineItem.variableAVGCheck = item.avg;
lineItem.variableSVCheck = item.svData;
lineItem.longName = item.name;
lineItem.priority = item.priority;
}
}
}
}
}
public class LineItems
{
public string variableName;
public string variableUnit;
public bool variableGrowthCheck;
public bool variableAVGCheck;
public bool variableSVCheck;
public string longName;
public int priority;
}
public class varMapper
{
public string Items { get; set; }
public string Unit { get; set; }
public bool growth { get; set; }
public bool avg { get; set; }
public bool svData { get; set; }
public string name { get; set; }
public int priority { get; set; }
}
You should write your method to return a list.
public List<LineItems> GetMapper()
{
using (var StreamReader = new StreamReader(#"D:\Data\Projects\dictUnitMapper.csv"))
{
using (var CsvReader = new CsvHelper.CsvReader(StreamReader, CultureInfo.InvariantCulture))
{
return
CsvReader
.GetRecords<varMapper>()
.Where(item => item.name != "#N/A")
.Where(item => item.priority != 0)
.Select(item => new LineItems()
{
variableName = item.Items,
variableUnit = item.Unit,
variableGrowthCheck = item.growth,
variableAVGCheck = item.avg,
variableSVCheck = item.svData,
longName = item.name,
priority = item.priority,
})
.ToList();
}
}
}
Here's an alternative syntax for building the return value:
return
(
from item in CsvReader.GetRecords<varMapper>()
where item.name != "#N/A"
where item.priority != 0
select new LineItems()
{
variableName = item.Items,
variableUnit = item.Unit,
variableGrowthCheck = item.growth,
variableAVGCheck = item.avg,
variableSVCheck = item.svData,
longName = item.name,
priority = item.priority,
}
).ToList();

Thank you.
Please check from Json output i wanted using JavaScriptSerializer. Then check class helper i created using json2csharp.com. Problem is in controller. I am not getting correct output as per my required Jason. I am doing correct in controller? Where the problem can be? Please ask question if you want to know something specific, sorry its hard to describe more clearly.
Helper Class Code:
public class ItemsFromFile
{
public string ASIN { get; set; }
public string Title { get; set; }
public List<Product> products { get; set; }
}
public class ItemsDeatails
{
public List<ItemsFromFile> ItemsFromFile { get; set; }
}
public class File
{
public string nameLocator { get; set; }
public ItemsDeatails itemsDeatails { get; set; }
}
public class RootObject
{
public string Token { get; set; }
public File file { get; set; }
}
Controller code:
if (type == "Salefreaks")
{
var token = ctx.BulkStores.FirstOrDefault(x => x.StoreName == store && x.Type == 1).Token;
var ItemsFromFile = new ItemsFromFile()
{
products = new List<Product>()
};
var ItemsDeatails = new ItemsDeatails()
{
};
var File = new File()
{
nameLocator = "testimport1"
};
var RootObject = new RootObject()
{
Token = token
};
var singleItems = ctx.BulkScannedItems.Where(x => x.UserSellerScanRequestId == id).ToList();
foreach (var item in singleItems)
{
ItemsFromFile.products.Add(new Product { ASIN = item.ASIN, Title = item.EbayTitle });
}
var json = new JavaScriptSerializer().Serialize(RootObject);
}
Required Json Output code:
{
"Token": "7f3099b0-36b1",
"file": {
"nameLocator": "testimport1",
"itemsDeatails": {
"ItemsFromFile": [
{
"ASIN": "B011KVFT9Y",
"Title": "Disney Batman Durable Party Beach Outdoor Adventure Camp Chair w/ Storage Bag"
},
{
"ASIN": "B01D4KRBW2",
"Title": "High Quality Diy Oil Painting Paint Number Kit Theme-Romantic Street A Frameless"
}
]
}
}
}
You can initialize internal objects in the code in the constructor as well.
public class RootObject
{
public string Token { get; set; }
public File file { get; set; }
}
public class File
{
public File()
{
this.itemsDeatails = new ItemsDeatails();
}
public string nameLocator { get; set; }
public ItemsDeatails itemsDeatails { get; set; }
}
public class ItemsDeatails
{
public ItemsDeatails(){
this.ItemsFromFile = new List<ItemsFromFile>();
}
public List<ItemsFromFile> ItemsFromFile { get; set; }
}
public class ItemsFromFile
{
public ItemsFromFile(){
this.products = new List<Product>();
}
public List<Product> products { get; set; }
}
public class Product {
public string ASIN { get; set; }
public string Title { get; set; }
}
Initialize your items properly. And create Root Object from the ground up.
Populate the internal classes first and then later ones.
var itemDetails = new ItemsDeatails();
itemDetails.ItemsFromFile = new ItemsFromFile();
var singleItems = ctx.BulkScannedItems.Where(x => x.UserSellerScanRequestId == id).ToList();
foreach (var item in singleItems)
{
itemDetails.ItemsFromFile.products.Add(new Product { ASIN = item.ASIN, Title = item.EbayTitle });
}
var fl = new File(){
nameLocator = "testimport1",
itemsDeatails = itemDetails
}
var token = ctx.BulkStores.FirstOrDefault(x => x.StoreName == store && x.Type == 1).Token;
var root = new RootObject()
{
Token = token,
file = fl
}
var json = new JavaScriptSerializer().Serialize(root);
Ensure that all your objects are assigned appropriately.
var token = ctx.BulkStores.FirstOrDefault(x => x.StoreName == store && x.Type == 1).Token;
var RootObject = new RootObject() {
Token = token,
file = new File() {
nameLocator = "testimport1",
itemsDeatails = new ItemsDeatails() {
ItemsFromFile = new List<ItemsFromFile>()
}
}
};
var itemsFromFile = new ItemsFromFile();
itemsFromFile.products = new List<Product>();
var singleItems = ctx.BulkScannedItems.Where(x => x.UserSellerScanRequestId == id).ToList();
foreach (var item in singleItems) {
itemsFromFile.products.Add(new Product { ASIN = item.ASIN, Title = item.EbayTitle });
}
RootObject.file.itemsDeatails.ItemsFromFile.Add(itemsFromFile);
var json = new JavaScriptSerializer().Serialize(RootObject);
That being said, it appears that you do not need the list of products inside of the ItemsFromFile class. This definition likely makes more sense:
public class ItemsFromFile {
public string ASIN { get; set; }
public string Title { get; set; }
}
Then your code would be something like this:
var token = ctx.BulkStores.FirstOrDefault(x => x.StoreName == store && x.Type == 1).Token;
var RootObject = new RootObject() {
Token = token,
file = new File() {
nameLocator = "testimport1",
itemsDeatails = new ItemsDeatails() {
ItemsFromFile = new List<ItemsFromFile>()
}
}
};
var singleItems = ctx.BulkScannedItems.Where(x => x.UserSellerScanRequestId == id).ToList();
foreach (var item in singleItems) {
RootObject.file.itemsDeatails.ItemsFromFile.Add(new ItemsFromFile { ASIN = item.ASIN, Title = item.EbayTitle });
}
I have following classes:
public class ProviderQualificationTimeViewModel
{
public string SessionId { get; set; }
public List<ProviderQualificationDetail> ProviderQualificationDetails { get; set; }
}
public class ProviderQualificationDetail
{
public string ProviderName { get; set; }
public string ProviderQualificationTime { get; set; }
public string TotalServiceableOffers { get; set; }
}
Basically, I want to create a new object if condition is true else I want to update ProviderQualificationDetail.ProviderQualificationTime where ProviderQualificationDetail.ProviderName == providerName
Is it possible using lambda expression?
List<ProviderQualificationDetail> providerQualificationDetail = new List<ProviderQualificationDetail>();
foreach (ProviderModel providers in allProviders)
{
if(!providerQualificationDetail.Any(p=>p.ProviderName.Contains(providerName)))
{
ProviderQualificationDetail ProviderQualificationDetail = new ProviderQualificationDetail();
ProviderQualificationDetail.ProviderName = providerName;
ProviderQualificationDetail.ProviderQualificationTime = Math.Round(processingTime).ToString();
ProviderQualificationDetail.TotalServiceableOffers = "Not serviceable";
providerQualificationDetail.Add(ProviderQualificationDetail);
}
else
{
//Lambda expression here
}
}
like this in else part:
foreach (var item in providerQualificationDetail.Where(x => x.ProviderName== providerName))
{
item.ProviderQualificationTime = Math.Round(processingTime).ToString();
}
Or
providerQualificationDetail.Where(x => x.ProviderName == ProviderName).Select(c =>
{
c.ProviderQualificationTime = "new time ";
return providerQualificationDetail;
}).ToList();
Or
providerQualificationDetail.ForEach(x =>
{
if(x.ProviderName == ProviderName)
x.ProviderQualificationTime = "new time";
});
Try this....
List<ProviderQualificationDetail> providerQualificationDetail = new List<ProviderQualificationDetail>();
foreach (ProviderModel providers in allProviders)
{
if(!providerQualificationDetail.Any(p=>p.ProviderName.Contains(providerName)))
{
ProviderQualificationDetail ProviderQualificationDetail = new ProviderQualificationDetail();
ProviderQualificationDetail.ProviderName = providerName;
ProviderQualificationDetail.ProviderQualificationTime = Math.Round(processingTime).ToString();
ProviderQualificationDetail.TotalServiceableOffers = "Not serviceable";
providerQualificationDetail.Add(ProviderQualificationDetail);
}
else
{
var qualificationDetail = providerQualificationDetail.SingleOrDefault(p => p.ProviderName.Equals(providerName));
//Assing your values here
//example;
qualificationDetail.ProviderName = NewProviderName.ToString();
providerQualificationDetail.SaveChanges();
}
}
I have an MVC VS2013 project querying an XML document.
The index action on my controller returns a list of Restaurants, and I need to be able to click the individual restaurants and open a details page which will show the respective properties of that Restaurant.
In previous projects querying from a sql database I would just call the db context, for example
Restaurant restaurant = db.Restaurants.Find(id);
but I am uncertain what the XML querying equivalent is.
Here is what I have so far.
Model:
[XmlRoot("EstablishmentCollection")]
public class Restaurant
{
[Key]
[XmlElement("FHRSID")]
public int? FHRSID { get; set; }
[XmlElement("BusinessName")]
public string BusinessName { get; set; }
[XmlElement("RatingValue")]
public int? RatingValue { get; set; }
[XmlElement("Hygiene")]
public int? HygieneScore { get; set; }
}
Controller:
public ActionResult Index()
{
IQueryable<Restaurant> Res = null;
try
{
var qy = xmlDoc.Descendants("EstablishmentDetail").Select(n => new Restaurant()
{
FHRSID = (int)n.Element("FHRSID"),
BusinessName = n.Element("BusinessName").Value,
RatingValue = RValue(n),
HygieneScore = HScores(n)
});
Res = qy.AsQueryable();
}
catch (Exception ex)
{
string message;
message = ex.Message.ToString();
return View(message);
}
return View(Res);
}
public ActionResult Details (int? id)
{
try
{
var qy = xmlDoc.Descendants("EstablishmentDetail").Select(n => new Restaurant()
{
FHRSID = (int)n.Element("FHRSID"),
BusinessName = n.Element("BusinessName").Value,
RatingValue = RValue(n),
HygieneScore = HScores(n)
});
//What goes here???
}
catch (Exception ex)
{
string message;
message = ex.Message.ToString();
return View(message);
}
return View();
}
Details View:
#model WebApplication3.Models.Restaurant
<h2>Details</h2>
<h6>#Model.FHRSID</h6>
<h6>#Model.BusinessName</h6>
<h6>#Model.HygieneScore</h6>
<h6>#Model.RatingValue</h6>
EDIT:
I have been working on it, is something like the below heading in the right direction?
(Controller)
public ActionResult Details (int? id)
{
var qy = xmlDoc.Descendants("EstablishmentDetail").Select(n => new Restaurant()
{
FHRSID = (int)n.Element("FHRSID"),
BusinessName = n.Element("BusinessName").Value,
RatingValue = RValue(n),
HygieneScore = HScores(n)
}).ToList();
var query = from x in qy
where x.FHRSID == id
select new Restaurant();
return View(query);
}
Problem with the above is that I am having issues correctly sending the query to the view
var r = xmlDoc.Descendants("EstablishmentDetail")
.Select(n => new Restaurant()
{
FHRSID = (int)n.Element("FHRSID"),
BusinessName = n.Element("BusinessName").Value,
RatingValue = RValue(n),
HygieneScore = HScores(n)
})
.Single(r => r.FHRSID == id);
Single, SignleOrDefault, First, FirstOrDefault returns an element from a collection.
