    OrderBy selfmade property on parentnode razor

    Im trying to order a list of nodes..

    foreach (var item in sizecollection.OrderBy("Parent.wwwidth"))
{


    @item.Parent.wwwidth


}

    this returns an error "Sequence contains no elements"

    this...

     foreach (var item in sizecollection.OrderBy("Parent.Name"))
{


    @item.Parent.wwwidth


}

    Does what you would expect and orders the nodes by their parents names. all nodes in sizecollection has a parent with a nonempty property with the alias "wwwidth".

    Thanks in advance.

    I would do it using LINQ like this:

    foreach (var item in sizecollection.OrderBy(i => i.Parent.GetPropertyValue<int>("wwwidth"))
{

}

    Assuming that wwwidth is an int. If it was a string you'd use GetPropertyValue<string> instead.

    Hello Dan

    Your answer gives me:

    "error CS1977: Cannot use a lambda expression as an argument to a dynamically dispatched operation without first casting it to a delegate or expression tree type"

    Hi Simon,

    How are you declaring sizecollection? Is it a typed object or a dynamic object. I suspect it is dynamic based on the error you are getting.

    Thanks,

    Nik

    Hi Nik

    Its dynamic. 

    var id = Request.QueryString["id"];

    var product = Umbraco.Content(id);

    var sizelist = product.wwstr.ToString().Split(new string[] { "," }, StringSplitOptions.RemoveEmptyEntries);
        var sizecollection = Umbraco.Content(sizelist);

    So, if you use a non-dynamic way to initialise sizecollection then my code should work, I think. So try:

    var sizecollection = Umbraco.TypedContent(sizelist);

foreach (var item in sizecollection.OrderBy(i => i.Parent.GetPropertyValue<int>("wwwidth"))
{

}
