                <ListBox  x:Name="lstPSGroups1" ItemsSource="{Binding Path=obj}" SelectionMode="Extended"  DisplayMemberPath="ModuleName" AllowDrop="True" Drop="lstPSGroups_Drop">
                   <ListBox.ItemsPanel>
                        <ItemsPanelTemplate>
                            <StackPanel Orientation="Vertical"/>
