[Solved] cannot use a lambda expression as an argument to a dynamically dispatched operation

[John]

I'm new to Telerik and my company has purchased the MVC ASP.NET controls.  I'm trying to bind a List<Gadget> to the TreeView control.  Here is my view:

@{

                Html.Telerik().TreeView()

                    .Name("TreeView")

                    .DragAndDrop(settings => settings

                        .DropTargets(".drop-area")

                    )

                    .ClientEvents(events => events

                    .OnNodeDrop("onNodeDrop")

                    .OnNodeDragging("onNodeDragging")

                )

                .BindTo(Model, mappings => {

                })

                .Render();

            }


However, I'm receiving the following error:

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

The error is occuring on the following line:
.BindTo(Model, mappings => {

Am I doing something wrong?

Hello John,

It is most likely that the page Model is not of an IEnumerable type, or that System.Data.Linq is not included for the code of the View. See the "Compilation error when binding navigation component" section of the troubleshooting help topic.

Adding the following line to the CSHTML file did the trick:

@model IEnumerable<IGadget>
