I have an object datasource that looks like this:

<asp:ObjectDataSource ID="obdsList" runat="server" 
EnablePaging="True" SelectCountMethod="GetCountByID" SortParameterName="sortExpression"
    OldValuesParameterFormatString="original_{0}" SelectMethod="GetByID" 
    TypeName="Services.Users" 
    onselected="obdsList_Selected">
    <SelectParameters>
        <asp:QueryStringParameter Name="ID" QueryStringField="ID" 
            Type="Int32" />           
    </SelectParameters>
</asp:ObjectDataSource>

And a onselected event like this:

protected void obdsList_Selected(object sender, ObjectDataSourceStatusEventArgs e) {
}

However, the event method is being called twice.. once with my returned list, and once with the returned Int32 count. If I want to cast e.ReturnValue to the return List how do I differentiate between the count and select methods? I can do a e.ReturnValue.GetType().ToString() but that seems like a hack.
