  How can i display Values on my List (Razor MVC)

  Jan 23, 2020 03:10 PM|MVC_user|LINK

  This is my Model:

       public void GetCategoryList()
          {
              ListComplexOrderCat = new List<ComplexBaseProperty<int, string>>();
  
              if (true) 
              {
  
                  var ListOfCategories = GetContentsRestClient().Get<List<CategoryContentChannel>>("Category"); 
  
                  if (ListOfCategories == null || ListOfCategories.Count == 0)
                  {
                      Console.WriteLine("Error, No existen Categorias para insertar un nuevo Articulo");
                  }
                  else
                  {
                      foreach (CategoryContentChannel category in ListOfCategories) 
                      {
                          ComplexBaseProperty<int, string> comPropCat = new ComplexBaseProperty<int, string>(
                              id: category.Id,
                              value: category.Description.ToString()
                          );
                          ListComplexOrderCat.Add(comPropCat); 
                      }
                  }
              }

  "ListComplexOrderCat" is a complex List such as:

  (Proprety ID / Property Value)

  {Id: 1} {Description: Category Random Text 1}

  {Id: 2} {Description: Category Random Text 2}

  {Id: 3} {Description: Category Random Text 3}

  Some Random Namespace
  {
      [DataContract]
      public class ComplexBaseProperty<I, T> : IEquatable<ComplexBaseProperty<I, T>>, IEqualityComparer<ComplexBaseProperty<I, T>>
      {
          public ComplexBaseProperty();
          public ComplexBaseProperty(I id);
          public ComplexBaseProperty(I id, T value);
  
          [Column("Id")]
          [DataMember(Name = "id")]
          public I Id { get; set; }
          [Column("Value")]
          [DataMember(Name = "value")]
          public T Value { get; set; }
  
          public override bool Equals(object obj);
          public bool Equals(ComplexBaseProperty<I, T> other);
          public bool Equals(ComplexBaseProperty<I, T> x, ComplexBaseProperty<I, T> y);
          public override int GetHashCode();
          public int GetHashCode(ComplexBaseProperty<I, T> obj);
      }
  }

  This is my Index:

  @Html.SelectFormFor(m => m.ListComplexOrderCat.Value, m => m.ListComplexOrderCat.Value, (SelectBaseListAdapter<int, string>)ViewBag.ListDisplayCategory);

  So basically my get is returning my list of values... now how can i desplay this? and save the values? 

  There is a variable on my Model "IdCategory" wich i should use to save de Id selected on the display List. 

  I Also use another list (for other purpose) working as:

  @Html.SelectFormFor(m => m.Article.Order, m => m.Article.Order, (SelectBaseListAdapter<int, string>)ViewBag.ListDisplayOrder);

  on that case Article is the Entity for my Model. however for Category list im using values outside this Entity. (I cant use Article).

  Come on man!   You're showing the community a custom html helper call, @Html.SelectFormFor(), that clearly is designed for your custom generic class.  Then ask.

  Seriously?  You must realize we can only see the code you share.

  I fixed this using a checkbox list instead of a list. (have scence if i want to use multiple values).

              for (int i = 0; i < Model.Categories.Count; i++)
              {
  
                  @Html.HiddenFor(m => m.Categories[i].Value);
                  @Html.HiddenFor(m => m.Categories[i].Text);
                  <label>@Html.CheckBoxFor(m => m.Categories[i].Selected)&nbsp;@Model.Categories[i].Text</label>
                  <br />
              }
