来自不同列表视图的多个项目拖放 WPF

Question

在 wpf 应用程序中，我有多个 ListView。 在一个工作流程中，我必须 select 来自不同列表视图的多个项目并将所有项目拖放到另一个控件。

单个列表视图中的多个项目实现如下。 谁能建议 select 来自不同列表视图的多个项目的可能性

XAML

<ItemsControl  Name="groupsTab" ItemsSource="{Binding Stores}" Margin="0,0,10,10" >
    <ItemsControl.ItemTemplate >
        <DataTemplate>
            <GroupBox Name="groupsGroupBox" AllowDrop="True"  ScrollViewer.HorizontalScrollBarVisibility="Hidden" 
      ScrollViewer.VerticalScrollBarVisibility="Visible" 
      ScrollViewer.IsDeferredScrollingEnabled="True" Margin="0,0,10,10">
                <GroupBox.Header>
                    <TextBlock   Text="{Binding StoreName}" FontWeight="Bold" PreviewMouseDown="BeatHeaderClick"  />
                </GroupBox.Header>
                <GroupBox.Content>
                    <ItemsControl ItemsSource="{Binding Branches}" Height="{Binding Path=GridHeight}">
