原文:WPF 隐藏式控件
没用Popup用的面板控件，全部代码使用xaml的触发器。
代码：
<Grid>
<DockPanel>
<StackPanel Background="Red" Height="40" DockPanel.Dock="Top">
<Button x:Name="ShowPanelBtn" Height="40" Width="40" HorizontalAlignment="Right">
<Button.Style>
<Style TargetType="Button">
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="true">
<Setter Property="Content" Value="∨"/>
</Trigger>
<Trigger Property="IsMouseOver" Value="false">
<Setter Property="Content" Value="∧"/>
</Trigger>
</Style.Triggers>
</Style>
</Button.Style>
</Button>
</StackPanel>
<Grid Background="Green" x:Name="DownPanel" Height="40" VerticalAlignment="Top">
<Grid.Style>
<Style TargetType="Grid">
<Style.Triggers>
<DataTrigger Binding="{Binding ElementName=ShowPanelBtn,Path=IsMouseOver}" Value="true">
<Setter Property="Visibility" Value="Visible"/>
</DataTrigger>
<DataTrigger Binding="{Binding ElementName=ShowPanelBtn,Path=IsMouseOver}" Value="false">
<Setter Property="Visibility" Value="Collapsed"/>
</DataTrigger>
</Style.Triggers>
</Style>
</Grid.Style>
</Grid>
</DockPanel>
</Grid>
