    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="Button">
                <Grid x:Name="RootGrid" Background="{TemplateBinding Background}">

</Style>

问题是当我按下按钮时,文本块不会改变前景色 你有什么想法我怎么能纠正我的代码 谢谢你的帮助

更新

这是我的xaml代码和Textblock,当我按下按钮时,我想将文本颜色从Gray更改为#00a0e3:

<Button Style="{Binding Source={StaticResource ButtonStyle}}">
                                        <Grid Margin="0" x:Name="Grid2" >
                                        <Grid.ColumnDefinitions>
                                            <ColumnDefinition Width="50"  />
                                            <ColumnDefinition Width="*" />
                                        </Grid.ColumnDefinitions>
                                        <Button Grid.Column="0" Click="MenuButton2_Click">
                                            <Image Source="images/3.png" Height="25" Width="25"  x:Name="img2" Margin="0"/>
                                        </Button>
                                        <TextBlock  Text="Restaurant"  Foreground="Gray" x:Name="res3" Grid.Column="1"/>
                                    </Grid>
                                </Button>

响应更新, 看到你想要完全不同的东西。需要更改其前景的TextBlock位于ContentPresenter Button控件的<Button Grid.Column="0" Tapped="MenuButton2_Tapped"> <Image Source="images/3.png" Height="25" Width="25" x:Name="img2" Margin="0"/> </Button> <TextBlock x:Name=restaurantTextBlock Text="Restaurant" Foreground="Gray" x:Name="res3" Grid.Column="1"/> 之外。因此,通过它的风格,您无法修改前景。您需要将Tap事件添加到按钮,然后从后端代码中更改前景色。请参阅以下代码。

在XAML中 -

restaurantTextBlock.Foreground = new SolidColorBrush(Color.FromArgb(255,0,160,227));//mention any color

在C#---

{{1}}

正如Romasz所指出的那样,在按下状态即#00a0e3时,您将按钮的前景颜色设置为与按钮的前景颜色相同。我认为在复制十六进制代码时,您可能粘贴错了。在“按下”状态或“初始前景”测试中更改颜色。只要进行了任何更改,您的代码就可以正常工作。

与往常一样,如果您觉得这个答案有用且正确,请将此答案作为正确答案投票。如果你愿意,欢迎你再提问。
