Question

我正在尝试禁用掉落目标，除了avalon dock中的目标。在codeplex中找不到任何文档。我在stackoverflow here中找到了一个类似的问题，但没有正确的回答，所以再次询问。

作为一个选项，您可以覆盖OverlayWindow控件样式并从中删除或更改拖放区域：

<Style x:Key="{x:Type avalonDockControls:OverlayWindow}"
     TargetType="{x:Type avalonDockControls:OverlayWindow}">
...
        <Grid x:Name="PART_AnchorablePaneDropTargets">
          <Grid Width="88"
                Height="88"
