[Solved] Filter using reflection

[Gabriel]

I want built filters in runtime. (Server -side code).
I need do something how this:

Html.Telerik()
.Grid(Model)
.Name("MyGrid")
.Filterable
(filtering => filtering.Filters
        (filter =>
            {
                if (filterCollection != null)
                {
                          foreach(FilterObject  filtercondition in filterCollection)
                            filter.Add (o => o.GetType().GetProperty( filtercondition.FieldName).GetValue(o, null) ).IsEqualTo( filtercondition.Value);

                }
             }
         )
);

This code isn't working.  Can you help me?
Many thanks.
