    Hi, I'm trying to bind a RadComboBox with an ObjectDataSource (odsFuenteEmisionAlcance) that returns a List of Objects like these:

    List<FuenteEmisionAlcance>
     
    public class FuenteEmisionAlcance
    {
        private FuenteEmision m_FuenteEmision;
        private Alcance m_Alcance;
      
        public FuenteEmision FuenteEmision
        {
            get { return m_FuenteEmision; }
            set { m_FuenteEmision = value; }
        }
     
        public Alcance Alcance
        {
            get { return m_Alcance; }
            set { m_Alcance = value; }
        }
    }

    This is my ComboBox

    <telerik:RadComboBox ID="rcbFuenteEmision" runat="server" AutoPostBack="True" DataSourceID="odsFuenteEmisionAlcance" DataTextField="FuenteEmision.Nombre" DataValueField="FuenteEmision.Id" ZIndex="100000" CausesValidation="False" OnSelectedIndexChanged="rcbFuenteEmision_SelectedIndexChanged" EmptyMessage="--Seleccione--" OnClientSelectedIndexChanged="OnClientSelectedIndexChanged" OnDataBinding="rcbFuenteEmision_DataBinding"></telerik:RadComboBox>

    I'm trying to use the DataTextField and DataValueField values from the Property FuenteEmision, but somehow is not getting it, this is what I get:

    [NotSupportedException: Object of type HUC.FuenteEmisionAlcance does not have a FuenteEmision.Nombre property.]


    Like I show before the object FuenteEmisionAlcance does a have a FuenteEmision property, the combo is able to find it, i've tried using only DataTextField="FuenteEmision" and DataValueField="FuenteEmision" just to try and it does find it, but when it comes to find a property from the property it crashes, is this impossible? or there is another way I can acomplish this.

    Hi Carlos Fernando,

    Please have a look into this help documentation and online demo which shows binding of RadComboBox using ObjectDataSource. Please provide your full code if it doesn't help.

    Thanks,
    Shinu.
