>>>Hi,

This is the definition of the datasource that is supposed to give the combo the items that the user can select (or at least that's what I understand it is supposed to be doing, but could be completely wrong):

OK, I found some sample code on-line and this is what I can try:

<asp:ObjectDataSource ID="odsRiders" runat="server" SelectMethod="GetRidersAndWaiversByPlan"
                                    TypeName="SamaanSystems.IAS.Business.Plan">
                                    <selectparameters>
                                        <asp:querystringparameter name="planPK"  querystringfield="planpk" defaultvalue="-1" />
                                    </selectparameters>
                                    </asp:ObjectDataSource>

However, I am not using a querystring to pass in the value I need. I can access the value in the aspx.cs file like this: this.oPolicy.Entity.PlanFK

So how would I use that in the aspx file?
