选中切换按钮时更改切换按钮的背景颜色

问题描述

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.

I want to change the background color of a toggle button when the toggle button is checked and vice versa.

我怎样才能做到这一点?

How can I achieve that?

推荐答案

<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 的几乎相同，但使用TemplateBinding"而不是TargetName".通过 TemplateBinding，ControlTemplate 使用 ToggleButtons DefaultStyle 中的 BorderBrush 和 Background.因此 Trigger 可以设置 ToggleButtons 背景和边框，这也将显示.

Nearly the same as Klaus ones, but using "TemplateBinding" instead of "TargetName".With the TemplateBinding, the ControlTemplate use the BorderBrush and Background from the ToggleButtons DefaultStyle. So the Trigger can set the ToggleButtons Background and with the Border this one will also be shown.
