    How to display the items by sortId in Razor?

    I have a list of items displayed at 'creation' id likte this:

     dynamic brochureLijst = Model.brochures.Item;
         if (brochureLijst.Count() != 0)
            {
                <ul>
                @foreach (var brochure in brochureLijst)
                {
                 <li> @brochure.naam</li>
                }
                </ul>
            }

    But I would like to display them by there 'sortId'

    I can't get this work. The 'soloutions' I found are based on nodes. How do I sort/order a list of items?

     <brochures>
            <Items>
              <Item id="1" sortId="2">
                <naam><![CDATA[Peter]]></naam>
              </Item>
              <Item id="2" sortId="3">
                <naam><![CDATA[Jack]]></naam>
              </Item>
              <Item id="3" sortId="1">
                <naam><![CDATA[John]]></naam>
              </Item>
            </Items>
          </brochures>

    Hi Robbie,

    I think you should be able to do something like:

    @foreach(var brochure in brochureLijst.OrderBy(item => item.sortId))

    This is just a guess though so let me know how you get on.

    Thanks
    Ben

    Hi Ben,

    I also thought that it wil do the trick.

    So I tried it again, but get the error in VS on the lambda saying "Cannot use a lambda expression as an argument to a dynamically dispatched operation without first casting it to a delegate or expression tree type".
    Is it because of the use of 'dynamic'?

    Ok, not ideal but the problem is because dynamic isn't IEnumerable, try something like: 

    @{
      List<dynamic> items = new List<dynamic>();
        
      foreach (dynamic item in Model.multiType)
      {       
       
       items.Add(new {
         Id = item.id,
         sortId = item.sortId,
         Name = item.name
       });
      }

    }

    @foreach(var item in items.OrderBy(i => i.sortId)){
      <p>@item.sortId, @item.Name</p>
    }

    Basically you have to create a list of all your items which you can then use lambda expressions on.

    Had the same problem. Solved it by abandoning razor. No time for that. Sadly - thats why xslt still will be around for a long time to come :-)
