[Solved] Model with dynamic properties

[Cristian]

Does the MVC Grid support showing dynamic properties from a DynamicObject model?

Let me explain my scenario.  This is a sample model:

Public Class ModelX
    Inherits Dynamic.DynamicObject
 End Class

This is a sample controller:

Public Class DemoController
    Inherits Controller

    Public Function Index() As ActionResult
        Dim list As New List(Of ModelX)
        Dim item As Object

        item = New ModelX
        item.PropertyA = 1
        item.PropertyB = "Something"
        list.Add(item)

        item = New ModelX
        item.PropertyA = 2
        item.PropertyB = "Something else"
        list.Add(item)

        item = New ModelX
        item.PropertyA = 3
        item.PropertyB = "Another thing"
        list.Add(item)

        Return View(list)
    End Function

End Class

And this is an extract of the view:

myGrid.Columns(Sub(header As Telerik.Web.Mvc.UI.Fluent.GridColumnFactory(Of TModelo))
    'this approach
    header.Bound("PropertyA")
    'or this another
    header.Bound(Of Integer)(ExpressionBuilder.Expression(Of TModelo, Integer)("PropertyA"))
    '...

Neither approach works as expected for me.  Is there a way to accomplish what I want?

Thanks for your help.
