当我编辑模板并进入 ItemContainerStyle 模板时,状态被定义为 Unselected、Selected、MouseOver 等。但实际上没有对这些状态进行任何操作。这种行为正常吗?我使用过 Silverlight 列表框。在其中,ItemContainerStyle 确实定义了所有状态,并且许多属性都已更改。WPF 列表框有点令人困惑。看到这是我编辑 ItemContainerStyle 时的 xaml:
<Style x:Key="ListBoxItemContainerStyle" TargetType="{x:Type ListBoxItem}">
<Setter Property="Background" Value="Transparent"/>
<Setter Property="HorizontalContentAlignment" Value="{Binding HorizontalContentAlignment, RelativeSource={RelativeSource AncestorType={x:Type ItemsControl}}}"/>
<Setter Property="VerticalContentAlignment" Value="{Binding VerticalContentAlignment, RelativeSource={RelativeSource AncestorType={x:Type ItemsControl}}}"/>
<Setter Property="Padding" Value="2,0,0,0"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ListBoxItem}">
<Border x:Name="Bd" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" Padding="{TemplateBinding Padding}" SnapsToDevicePixels="true" >
<VisualStateManager.VisualStateGroups>
<VisualStateGroup x:Name="CommonStates">
<VisualState x:Name="Normal"/>
<VisualState x:Name="MouseOver"/>
<VisualState x:Name="Disabled"/>
</VisualStateGroup>
<VisualStateGroup x:Name="SelectionStates">
<VisualState x:Name="Unselected"/>
<VisualState x:Name="Selected"/>
<VisualState x:Name="SelectedUnfocused"/>
</VisualStateGroup>
</VisualStateManager.VisualStateGroups>
<ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
这里只给出了一个 ContentPresenter。我想在鼠标悬停后更改渐变。我还想缩放项目的大小。我怎么做?
提前致谢 :)
