我很頭痛,試圖在鼠標移過它時改變按鈕的默認行爲。下面是部分代碼: (我省略的代碼,各種面板,並只保留代碼感興趣的面板)爲什麼此XAML無法按預期工作?
<Window.Resources>
<Style x:Key="leftPanelButtons" TargetType="{x:Type Button}">
.... various setters go here ....
<Setter Property="Background" Value="ForestGreen"/>
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" Value="DarkSeaGreen"/>
</Trigger>
</Style.Triggers>
</Style>
</Window.Resources>
<DockPanel Grid.Row="2">
<DockPanel Height="Auto" Width="Auto" VerticalAlignment="Stretch">
<UniformGrid Columns="1" Height="Auto" VerticalAlignment="Stretch" MinWidth="150" Width="Auto">
<UniformGrid.Resources>
<Style BasedOn="{StaticResource leftPanelButtons}" TargetType="Button"/>
</UniformGrid.Resources>
<Button>
button1
</Button>
<Button>
button2
</Button>
<Button>
button3
</Button>
</UniformGrid>
<StackPanel Height="Auto" Width="Auto" Background="PaleGoldenRod">
</StackPanel>
</DockPanel>
</DockPanel>
我期待按鈕的背景顏色設置爲森林綠和變化當鼠標移動到按鈕上時,轉到DarkSeaGreen。我確實獲得了ForestGreen顏色,但是當我將鼠標移動到按鈕上時,顏色變爲淺藍色變體。我有點複製了這個page的代碼。
