我有一个无边界的表格,当我尝试将其他表格拖到它上面时,它们只会在它下面而不是在它上面,为什么它会这样做?
WindowStartupLocation="CenterScreen" HorizontalAlignment="Left" VerticalAlignment="Top" MouseDown="Window_MouseDown" Topmost="True" x:Name="win" WindowStyle="None" Height="{x:Static SystemParameters.PrimaryScreenHeight}" Width="{x:Static SystemParameters.PrimaryScreenWidth}" ResizeMode="CanResizeWithGrip" AllowsTransparency="True" Visibility="Visible" SnapsToDevicePixels="True" IsHitTestVisible="True" Loaded="win_Loaded">
<WindowChrome.WindowChrome>
<WindowChrome
