Hi NewbApps,

Thank you for posting in the community.

You should be able to specify both your parent and child ObjectDataSources as DataViews in a WebHierarchicalDataSource. Afterwards you need to define the relation between them. For instance:


        <ig:WebHierarchicalDataSource ID="WebHierarchicalDataSource1" runat="server">
            <dataviews>
                <ig:DataView ID="parentObjectDataSource_DefaultView" DataMember="DefaultView" 
                    DataSourceID="categoryObjectDataSource" />
                <ig:DataView ID="childObjectDataSource_DefaultView" 
                    DataMember="DefaultView" DataSourceID="categoryObjectDataSource0" />
            </dataviews>
            <datarelations>
                <ig:DataRelation ChildColumns="Id" 
                    ChildDataViewID="childObjectDataSource_DefaultView" ParentColumns="Id" 
                    ParentDataViewID="parentObjectDataSource_DefaultView" />
            </datarelations>
        </ig:WebHierarchicalDataSource>

Please tell me if this helps.
