Binding RadComboBox with ObjectDataSource trough DataValueField="Property.Property"

[Carlos Fernando]

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,
