WPF 禁用按钮的背景 [英] WPF Disabled button's background

问题描述

我尝试在禁用按钮时更改按钮的样式:

I try to change button's style when it is disabled:

    <Style TargetType="Button" x:Key="MyButton2">
        <Setter Property="Background" Value="MediumAquamarine" />
        <Setter Property="Foreground" Value="MediumBlue" />

        <Style.Triggers>
            <Trigger Property="IsEnabled" Value="false">
                <Setter Property="Background" Value="Green"/>
                <Setter Property="Foreground" Value="DeepPink"/>
            </Trigger>
        </Style.Triggers>

    </Style>

和我的按钮:

<Button Style="{StaticResource MyButton2}" Content="My text" Width="100" Height="30" IsEnabled="False" />    

但是由于某种原因这种样式没有应用于按钮:

But for some reason This style is not applied to the button:

如何将这种样式应用到我的按钮上?我可以在不覆盖按钮模板的情况下只使用样式吗?

How can i apply this style to my button? And can i do it without overriding button's template only with styles?

推荐答案

我可以在不覆盖按钮模板的情况下只使用样式吗?

Can I do it without overriding button's template only with styles?

我认为不是，因为 Windows 中的控件具有默认的 Styles 和 ControlTemplates，并且 在每个版本的 Windows 中它们都是不同的.另外，样式——它只是很多设置，通常样式不会改变/添加行为到控件，它负责这个ControlTemplate.

I think not, because the Controls in the Windows has a default Styles and ControlTemplates and in each version of Windows they are different. In addition, the styles - it's just a lot of settings, usually the style does not change/add behavior to control, which is responsible for this ControlTemplate.

注: Style 是一组setter，例如:设置背景、大小等. ControlTemplate 是表单，其中所有这些将出现设置.

Note: the Style it is a set of setters, for example: set the background, size, etc. The ControlTemplate is the form, in which all of these settings will appear.

在这种情况下，我建议大家更改 ControlTemplate，无论系统版本如何，都可能具有相同的行为(即视图).

In this situation, I recommend you all to change the ControlTemplate, where it is possible to have the same behavior aka view, regardless of the version of the system.

在这种情况下，试试这个Style:

In this case, try this Style:

<Window.Resources>
    <Style TargetType="Button" x:Key="MyButton2">
        <Setter Property="OverridesDefaultStyle" Value="True" />
        <Setter Property="Background" Value="MediumAquamarine" />
        <Setter Property="Foreground" Value="MediumBlue" />

        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type Button}">
                    <Grid Background="{TemplateBinding Background}">
                        <ContentPresenter x:Name="MyContentPresenter" 
                                          Content="{TemplateBinding Content}"
                                          HorizontalAlignment="Center" 
                                          VerticalAlignment="Center" />
                    </Grid>
                </ControlTemplate>
            </Setter.Value>
        </Setter>

        <Style.Triggers>
            <Trigger Property="IsEnabled" Value="False">
                <Setter Property="Background" Value="Green"/>
                <Setter Property="Foreground" Value="DeepPink"/>
            </Trigger>
        </Style.Triggers>
    </Style>
</Window.Resources>

<Grid x:Name="LayoutRoot">
    <Button Content="Button" 
            IsEnabled="False"
            HorizontalAlignment="Left" 
            VerticalAlignment="Top" 
            Width="75" 
            Style="{StaticResource MyButton2}"
            Click="Button_Click"/>
</Grid>
