选中切换按钮时,更改切换按钮的背景颜色

Question

我想在选中切换按钮时更改切换按钮的背景颜色,反之亦然.

我怎样才能做到这一点？

Answer 1

<ToggleButton Content="toggle">
    <ToggleButton.Style>
        <Style TargetType="{x:Type ToggleButton}">
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="ToggleButton">
                        <Border BorderBrush="{TemplateBinding BorderBrush}" 
                                Background="{TemplateBinding Background}">
                            <ContentPresenter HorizontalAlignment="Center"                  
                                              VerticalAlignment="Center"/>
                        </Border>
                    </ControlTemplate>
                </Setter.Value>
            </Setter> 
            <Style.Triggers>
                <Trigger Property="IsChecked" Value="True">
                    <Setter Property="Background" Value="Red" />
                </Trigger>
            </Style.Triggers>
        </Style>
    </ToggleButton.Style>
</ToggleButton>

与Klaus几乎相同,但使用"TemplateBinding"而不是"TargetName".使用TemplateBinding,ControlTemplate使用ToggleButtons DefaultStyle中的BorderBrush和Background.因此Trigger可以设置ToggleButtons背景,而边框也会显示.

实现这一目标的最简单方法(并且没有任何Blend和覆盖50行XAML;)就是这种方式,即使用触发器:

<Window x:Class="StackOverflow.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Window1" Height="300" Width="300">
<Grid>
    <ToggleButton x:Name="tg" Height="20" Width="80">
        <ToggleButton.Style>
            <Style TargetType="{x:Type ToggleButton}">
                <Setter Property="Background" Value="Green"/>
                <Style.Triggers>
                    <Trigger Property="IsChecked" Value="true">
                        <Setter Property="Background" Value="Red"/>
                    </Trigger>
                </Style.Triggers>

            </Style>
        </ToggleButton.Style>
    </ToggleButton>
</Grid>

首先尝试这一点,然后再继续,看看它是否符合您的需求

检查此解决方案:

<Grid>
<Grid.Resources>
  <Style x:Key="ToggleButtonStyle1" TargetType="{x:Type ToggleButton}">
    <Setter Property="Template">
      <Setter.Value>
        <ControlTemplate TargetType="{x:Type ToggleButton}">
          <Border HorizontalAlignment="Center" VerticalAlignment="Center" x:Name="border" Padding="5,5,5,5" CornerRadius="5,5,5,5" Background="#FFBFACAC" BorderBrush="#FF000000" BorderThickness="1,1,1,1" SnapsToDevicePixels="True">
            <ContentPresenter x:Name="contentPresenter"/>
          </Border>
          <ControlTemplate.Triggers>
            <Trigger Property="IsChecked" Value="true">
              <Setter Property="Background" TargetName="border" Value="#FFC31010"/>
            </Trigger>
          </ControlTemplate.Triggers>
        </ControlTemplate>
      </Setter.Value>
    </Setter>
  </Style>
</Grid.Resources>

<ToggleButton Content="ToggleButton" Margin="25" Width="90" Height="45" Style="{StaticResource ToggleButtonStyle1}"/>

</Grid>

你有Expression Blend吗？右键单击ToggleButton并选择"编辑模板",然后选择"编辑副本..."即可轻松完成.从模板转到"状态"选项卡,然后选择"已检查"状态.重置背景颜色,与基本状态和完成时间不同.

见样本:
