    Passing a single value to an IEnumerable view

    With Umbraco 7, Visual Studio 2013 and MVC, I am using webGrid to display a list of links to documents, each with a date field.

    Accordingly, the data collected by the controller is a list and the View uses IEnumerable to display the collection in the webGrid.

    But I also need to pass a single value to the View (this value is the ID of the folder containing the documents). Because the View is IEnumerable, I can't work out how to get this single value.

    My code is as follows.

    using System;
        using System.Collections.Generic;
        using System.Linq;
        using System.Web;
    
        namespace ParishMaster.Models
        {
            public class DocumentList
            {
                public string Document { get; set; }
                public DateTime Date { get; set; }
                public string Description { get; set; }
                public string Url { get; set; }
                public string PageName { get; set; } //  This is the single value property.
            }
        }
    
    
        using ParishMaster.Models;
        using System;
        using System.Collections.Generic;
        using System.Linq;
        using System.Web;
        using System.Web.Mvc;
        using Umbraco.Web.Mvc;
    
        namespace ParishMaster.Controllers
        {
            public class DocumentListSurfaceController : SurfaceController
            {
                // GET: DocumentList
                public ActionResult Index()
                {
                    DocumentList vDocument = new DocumentList();
                    List<DocumentList> vDocumentList = new List<DocumentList>();
    
                    var page = Umbraco.Content(1096);
                    var vPageName = page.name;
                    vDocument.PageName = vPageName;  //This is the single value property
    
                    foreach (var child in page.Children)
                    {
                        vDocument = new DocumentList();
                        vDocument.Document = child.name;
                        vDocument.Date = child.dtpDocumentDate.Date;
                        vDocument.Description = child.dtpDocumentDescription;
                        vDocument.Url = Umbraco.Media(child.dtpDocumentFile).Url;
                        vDocumentList.Add(vDocument);
                    }
    
                    var data = vDocumentList;
    
                    return PartialView("DocumentList", data);
    
                }
            }
        }
    
    @model IEnumerable<ParishMaster.Models.DocumentList>
    
    @{
        WebGrid vGrid = new WebGrid(Model, defaultSort: "Date", rowsPerPage: 12);
    }
    
    <h3>
        @*How do I write the PageName property value here.*@
    </h3>
    
        @vGrid.GetHtml(
                alternatingRowStyle: "docList-alternating-row",
                tableStyle: "docList-table",
                headerStyle: "docList-header",
                footerStyle: "docList-footer",
                columns: new[] {
            vGrid.Column("Date", header: "Date"),
            vGrid.Column("Document", format: @<text><a href="@Href(item.Url)" target="_blank">@item.Document</a></text>),
        })
    

    Your help would be much appreciated.

    Thanking you in anticipation.

    Hi Roger,

    think you can add your single value to the viewbag and in the view output it.

    ViewBag.MyValue = "Test" @ViewBag.MyValue

    That should work.

    Hi Roger,

    Rather than adding the page.name to each DocumentList property in your List

    public class MyViewModel {
      public List<DocumentList> DocumentList { get; set; }
      public string PageName { get; set;}
    }
    

    Once you've built up your vDocumentList you can then add it all to the object:

    MyViewModel myViewModel = new MyViewModel {
      DocumentList = vDocumentList,
      PageName = page.name
    };
    

    and then pass that object back to your view:

    return PartialView("DocumentList", myViewModel);
    

    Thanks,

    Maff

    Thanks, Maff.

    I tried to implement your solution but I am getting an error when the view is called.

    My view is IEnumerable:

    @model IEnumerable<ParishMaster.Models.DocumentList>
    

    Won't this give an error if I send to it:

            DocumentList myViewModel = new DocumentList
            {
                Documents = vDocumentList,
                PageName = page.name
            };
    
            return PartialView("DocumentList", myViewModel);
    

    as you suggest?

    Roger

    Hi Roger,

    if you remove the IEnumerable in the view and just use @model yourModel then it should work.

    Thank, David.

    If I remove the IEnumerable, the PageName works but the webGrid gives an error on the WebGrid vGrid = new WebGrid line:

    @model ParishMaster.Models.DocumentList
    
    <h3>
        @Model.PageName
    </h3>
    
    @{
        WebGrid vGrid = new WebGrid(Model, defaultSort: "Date", rowsPerPage: 12); //error on this line.
    
    }
    
        @vGrid.GetHtml(
                alternatingRowStyle: "docList-alternating-row",
                tableStyle: "docList-table",
                headerStyle: "docList-header",
                footerStyle: "docList-footer",
                columns: new[] {
            vGrid.Column("Date", header: "Date"),
            vGrid.Column("Document", format: @<text><a href="@Href(item.Url)" target="_blank">@item.Document</a></text>),
        })
    

    because the webGrid wants a collection and therefore need an IEnumerable?

    Roger

    Hi Roger,

    think it is because you are using Model directly. Try to use Model.Documents instead. Think this should work.
