wpf定义ListBox样式

wpf定义ListBox样式

首先创建​​ListBox​​

<ListBox Style="{StaticResource MenuListStyle}">
  <ListBoxItem>ggg</ListBoxItem>
  <ListBoxItem>dddd</ListBoxItem>
  <ListBoxItem>dddd</ListBoxItem>
  <ListBoxItem>dddd</ListBoxItem>
</ListBox>

之后添加样式文件​​MenuList.xaml​​

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                    xmlns:local="clr-namespace:GraphElementGenerationSYS.Resources">
    <Style TargetType="{x:Type ListBox}" x:Key="MenuListStyle">
        <Setter Property="Width" Value="250"/>
        <!--<Setter Property="BorderThickness" Value="1"/>
        <Setter Property="BorderBrush" Value="Red"/>-->
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate>
                    <Border BorderBrush="Red" BorderThickness="1">
                        <ItemsPresenter></ItemsPresenter>
                    </Border>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

    <Style TargetType="{x:Type ListBoxItem}">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="ListBoxItem">
                    <Border Background="{TemplateBinding Background}">
                        <ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"
                                                 VerticalAlignment="{TemplateBinding VerticalContentAlignment}"
                                                 TextBlock.Foreground="{TemplateBinding Foreground}"/>
                    </Border>
                </ControlTemplate>
            </Setter.Value>
        </Setter>

        <!-- 设置触发器 -->
        <Style.Triggers>
            <Trigger Property="IsSelected" Value="true">
                <Setter Property="Background" Value="Black"/>
                <Setter Property="Foreground" Value="White"/>
            </Trigger>
            <Trigger Property="IsMouseOver" Value="true">
                <Setter Property="Background" Value="LightGreen"/>
                <Setter Property="Foreground" Value="Red"/>
            </Trigger>
        </Style.Triggers>
    </Style>
</ResourceDictionary>

最后在​​App.xaml​​中拼接起来就OK了

<Application.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary  Source="Resources/MenuList.xaml"/>
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>

    </Application.Resources>
