WPF RadioButton/ToggleButton样式

Question

我想模仿一组ToggleButtons的样式,如下图所示.任何时候只能"检查"其中一个按钮.

我的问题与样式有关:

• 我想在最左边的按钮和最右边的按钮上有圆角,如图中所示,但是如果有一个按钮(如图中所示),则不应该有圆角.有时可能只有两个按钮可以切换.
• 我需要不同状态的风格:"正常/未选中","鼠标悬停","按下"和"检查"至少.

我正在使用的当前控件是这样完成的:

<StackPanel Orientation="Horizontal" >
    <RadioButton Style="{StaticResource {x:Type ToggleButton}}" Content="All" Padding="12,8,12,8" GroupName="View"  />
    <RadioButton Style="{StaticResource {x:Type ToggleButton}}" Content="Geolocated" Padding="12,8,12,8" GroupName="View" />
    <RadioButton Style="{StaticResource {x:Type ToggleButton}}" Content="Non Geolocated" Padding="12,8,12,8" GroupName="View" />
</StackPanel>

在StackPanel资源中,我试图为ToggleButton设置Style,但我很遗憾如何在上图中获得结果.

这可能不是最简单/最好的方法,但是我尝试ControlTemplates使用Kaxaml来敲打一些东西,以产生如下所示的东西:

您可以将这些模板存储在a中ResourceDictionary并在需要时应用它们,或者在动态构建按钮列表时使用它们.

我实际上创建了三种稍微不同的样式,一种用于左右按钮,一种用于中间(您可以通过扩展/继承样式来简化这种情况).省略了一些重复代码.

<Grid>
    <Grid.Resources>
        <!-- Brushes for colours/backgrounds -->
        <SolidColorBrush x:Key="FontBrush" Color="#DDDDDD"/>

        <LinearGradientBrush x:Key="BgBrush1" StartPoint="0,0" EndPoint="0,1">
            <GradientStop Offset="0" Color="#888888"/>
            <GradientStop Offset="1" Color="#222222"/>
        </LinearGradientBrush>

        <SolidColorBrush x:Key="BorderBrush1" Color="#333333"/>
        <LinearGradientBrush x:Key="CheckedBrush" StartPoint="0,0" EndPoint="0,1">
            <GradientStop Offset="0" Color="#555555"/>
            <GradientStop Offset="1" Color="#111111"/>
        </LinearGradientBrush>

        <!-- Left Button Template -->
        <ControlTemplate x:Key="ToggleButtonLeft" TargetType="{x:Type ToggleButton}">
            <Border
                Name="Border"
                Background="{StaticResource BgBrush1}"
                BorderBrush="{StaticResource BorderBrush1}"
                BorderThickness="1"
                CornerRadius="5,0,0,5">
                <ContentPresenter
                    HorizontalAlignment="Center"
                    Margin="{TemplateBinding Padding}"
                    VerticalAlignment="Center"
                    Content="{TemplateBinding Content}"
                    TextBlock.FontWeight="Bold"
                    TextBlock.Foreground="{StaticResource FontBrush}"/>
            </Border>
            <ControlTemplate.Triggers>
                <Trigger Property="ToggleButton.IsMouseOver" Value="true">
                    <Setter TargetName="Border" Property="Background" Value="#808080"/>
                </Trigger>
                <Trigger Property="IsChecked" Value="true">
                    <Setter TargetName="Border" Property="Background" Value="{StaticResource CheckedBrush}"/>
                </Trigger>
            </ControlTemplate.Triggers>
        </ControlTemplate>

        <!-- Middle Button(s) Template -->
        <ControlTemplate x:Key="ToggleButtonMid" TargetType="{x:Type ToggleButton}">
            <Border
                Name="Border"
                Background="{StaticResource BgBrush1}"
                BorderBrush="{StaticResource BorderBrush1}"
                BorderThickness="0,1,0,1"
                CornerRadius="0" />
        <!-- Other code identical to Left Button Template -->       
        </ControlTemplate>

        <!-- Right Button Template -->
        <ControlTemplate x:Key="ToggleButtonRight" TargetType="{x:Type ToggleButton}">
            <Border
                Name="Border"
                Background="{StaticResource BgBrush1}"
                BorderBrush="{StaticResource BorderBrush1}"
                BorderThickness="1"
                CornerRadius="0, 5, 5, 0" />
        <!-- Other code identical to Left Button Template -->  
        </ControlTemplate>
    </Grid.Resources>

    <!-- Example Usage -->
    <Grid Background="#555555">
        <StackPanel Height="25" Orientation="Horizontal" Margin="5">
            <RadioButton Content="All" GroupName="View" Padding="2" Template="{DynamicResource ToggleButtonLeft}"/>
            <RadioButton Content="Geolocated" GroupName="View" Padding="2" Template="{DynamicResource ToggleButtonMid}"/>
            <RadioButton Content="Non Geolocated" GroupName="View" Padding="2" Template="{DynamicResource ToggleButtonRight}"/>
        </StackPanel>
    </Grid>
</Grid>

您必须Triggers为IsPressed州和其他任何其他所需的(例如IsEnabled)添加其他等.
