Combo box returning Null when DataValueField is set.

[Chris]

<asp:SqlDataSource ID="rejectReason" runat="server" ConnectionString="<%$ ConnectionStrings:qcData %>" SelectCommand="SELECT [id],[rejectCode] FROM [rejectionReasons]"></asp:SqlDataSource>

<ej:ComboBox runat="server" ID="NCRreason" CssClass="cbox" DataSourceID="rejectReason" DataSourceCachingMode="Session" DataTextField="rejectCode" DataValueField="id" AllowCustom="false" Placeholder="Select reason" AutoFill="True"></ej:ComboBox>

NCRreason.value in code behind is null.  If I remove the DataValueField the .value will be populated with the text.  I need the id associated with the text for my database.
