I have a hierarchical treeview in a formview. Is is possible to data bind to the treeview (two-way)?

ex:

    
                            <telerik:RadTreeView ID="rtvCategories" runat="server" 
        
                                DataSourceID="ldsCategories"  
        
                                DataFieldID="ID" DataFieldParentID="ParentID" 
        
                                DataTextField="Name" DataValueField="ID" 
        
                                SelectedValue='<% Bind("CategoryID") %>'> 
        
                            </telerik:RadTreeView> 
        
                            <asp:LinqDataSource ID="ldsCategories" runat="server"  
        
                                ContextTypeName="DataAccess.DataContext" TableName="Categories" > 
        
                            </asp:LinqDataSource>

I know you can't do it the way I do it above since "SelectedValue" is readonly. Is there a work around?
