I'm having trouble with the controlparameter of a ListBox which points to same RadGrid where the Listbox is used.

I want to populate the Listbox depending on the selected value of the Grid, so I've set a controlparameter in the datasource of the ListBox which points to the selectedItem of the Grid. However, the controlparameter always gets the default value. If I set the controlparameter to another grid (not the grid which is the parent of the ListBox) it works fine.

    
            <GRID id=g1 Datasource = DS1>     
        
                <VIEW> 
        
                <EDIT>    
        
                    <LISTBOX Datasource=DS2></LISTBOX>    
        
                </EDIT>    
        
            </GRID>    
        
            <DS1>    
        
                ...     
        
            </DS1>    
        
            <DS2>    
        
                <selectparameters>    
        
                    <asp:ControlParameter ControlID="g1" DefaultValue="0" Name="id" PropertyName="SelectedValue" Type="Int32" />      
        
                </selectparameters>    
        
            </DS2>
