Editable grid and dynamic type in MVC3/Razor

[Helene Lach]

I am trying to create an editable grid bound to a dynamic type, following the instructions in this blog. My page does not render, and I am getting the following error:

System.InvalidOperationException: Templates can be used only with field access, property access, single-dimension array index, or single-parameter custom indexer expressions.

Here is my code:

@model IEnumerable<dynamic>
@{
    ViewBag.Title = "Test";
}

<div>
    @(Html.Telerik().Grid(Model)
            .Name("TestGrid")
            .DataKeys(keys => keys.Add("Id"))
            .ToolBar(commands => commands.Insert())
            .DataBinding(dataBinding => dataBinding
                .Ajax()
                        .Select("AjaxIndex", "Test")
                        .Insert("Create", "Test")
                        .Update("Edit", "Test")
                        .Delete("Delete", "Test")
                )
            .Columns(columns =>
                {
                    columns.Bound("Name");
                    columns.Bound("Description");
                    columns.Command(commands =>
                    {
                        commands.Edit();
                        commands.Delete();
                    }).Width(180).Title("Commands");
                })
            .Editable(editable => editable.Mode(GridEditMode.InLine))
        )
</div>

Everything works fine if I replace dynamic with a real class, or if I keep the grid read-only. I am using the Q1 2011 Telerik extensions (2011.1.315).

I would appreciate any insight that would help me figure out what I am doing wrong!

Thanks,
Helene
