That helped but now I can set properties on it but it doesnt allow me to decalre diffrent instances.

I can do the following:

<sb:SBObjectDataSource runat="Server" ID="ods" ConnectionString="Data Source=HOU-SQLDEV03;Integrated Security=True"
        SelectCommand="SELECT * FROM Contacts; SELECT * FROM Issues;">
        <CacheManager />
    </sb:SBObjectDataSource>

But I want to be able to do the above and set the property to an instance of an object that is inherited from a base class.
