    I am using a class like the following:

    public class SLDocumentos
        public int Identificador { get; set; }
        public string Nombre { get; set; }
        public SLCatalogoDoc IDActividad { get; set; }
        public SLCatalogoCorp Compania { get; set; }
        public ObservableCollection<SLCatalogoPerson> Personal { get; set; }
        public DateTime? FechaActividad { get; set; }

    i made a Collection of that class and these are the items that i display in my RadGridView and now i want to filter it with the RadDataFilter but i have a trouble with this:

    public ObservableCollection<SLCatalogoPerson> Personal { get; set; }

    is possible filter it together with the other items??

    sorry for my poor english.

    Hi Arturo,

    That is not possible. RadDataFilter creates simple LINQ Expressions in order to filter the source collection. For example:

    sourceCollection.Where(person=>person.Name == "John")


    sourceCollection.Where(person.Salary > 1000)

    When the property is another collection, such an expression cannot be created.

    All the best,
