Binding Linq WhereSelectArrayIterator

[Torsten]

My linq expression:

Root root = Root.GetInstance();
           var betriebe =
               from w in root.Query(Betrieb.Entity).ToArray()
               select new
               {
                   Betriebegruppe = "0",
                   Betrieb = w.Get(Betrieb.Werk),
                   Name = w.Get(Betrieb.Name),
                   Strasse = w.Get(Betrieb.Strasse),
                   PLZ = w.Get(Betrieb.Postleitzahl),
                   Ort = w.Get(Betrieb.Ort),
                   EKORG = w.Get(Betrieb.Einkaufsorganisation)
               };

 

returns an iterator like this:

System.Linq.Enumerable.WhereSelectArrayIterator<P0300_DAL.Data.AnyObject,<>f__AnonymousType0<string,string,string,string,string,string,string>>

If I bind this as datasource to a radgrid everything works fine. But when I bind it to an radtreelist, the columns were generated but the content is empty.

Do I have to do more than: 

treelist.DataSource = betriebe;

?
Here is my treelist declaration:

<telerik:RadTreeList runat="server" ID="rtl" AllowSorting="True" AllowMultiItemSelection="True"
    CausesValidation="false" ParentDataKeyNames="Betriebegruppe" DataKeyNames="Betrieb"
    AllowPaging="True" PageSize="20" Width="100%">
    <Columns>
    <telerik:TreeListCheckBoxColumn ></telerik:TreeListCheckBoxColumn>
    </Columns>
    <ClientSettings>
        <Selecting AllowItemSelection="true" UseSelectColumnOnly="true" />
    </ClientSettings>
</telerik:RadTreeList>

Hello Torsten,

It seems that such binding is working on my side. For your convenience I am attaching sample page demonstrating binding to System.Linq.Enumerable.WhereSelectArrayIterator.

All the best,
