Question

我已经创建了一个像这样的TreeViewDragDropTarget，

<controlsToolKit:TreeViewDragDropTarget msWindows:DragDrop.AllowDrop="False" ItemDroppedOnTarget="TreeViewDragDropTarget_ItemDroppedOnTarget" ItemDragCompleted="TreeViewDragDropTarget_ItemDragCompleted" AllowedSourceEffects="Copy">
    <controlsToolKit:TreeViewDragDropTarget.Resources>
     <common:HierarchicalDataTemplate x:Key="hierarchicalTemplate" ItemsSource="{Binding ChildNode}">
      <TextBlock Text="{Binding MainText, Mode=TwoWay}" TextWrapping="Wrap"/>
     </common:HierarchicalDataTemplate>
    </controlsToolKit:TreeViewDragDropTarget.Resources>
    <controls:TreeView x:Name="MainTreeView" BorderThickness="1" ItemTemplate="{StaticResource hierarchicalTemplate}" Background="Transparent" Cursor="Hand" BorderBrush="{x:Null}" VerticalAlignment="Top"/>
   </controlsToolKit:TreeViewDragDropTarget>

All I am doing is dropping some text into the nodes of the treeview. I want to find the parent node of the drop target. How do I do it?

请查看此帖子。您需要使用treeview控件的Drop事件。 http://forums.silverlight.net/forums/p/190196/439403.aspx

在Silverlight中的TreeViewDragDropTarget中获取树视图的父节点
