C# UWP TextBlock 文本以编程方式更改按钮样式

Question

我有一个资源样式的按钮。我想更改按钮内容中 TextBlock 的文本。我没有找到任何解决方案。

有什么想法吗？

<Style x:Key="NavigationLogoutButtonStyle" TargetType="Button" BasedOn="{StaticResource NavigationBackButtonNormalStyle}">
<Setter Property="HorizontalAlignment" Value="Stretch"/>
<Setter Property="HorizontalContentAlignment" Value="Stretch"/>
<Setter Property="Height" Value="48"/>
<Setter Property="Width" Value="NaN"/>
<Setter Property="MinWidth" Value="48"/>
<Setter Property="AutomationProperties.Name" Value="Logout"/>
<Setter Property="Content">
    <Setter.Value>
        <Grid>
            <Grid.ColumnDefinitions>
                <ColumnDefinition Width="48" />
                <ColumnDefinition />
            </Grid.ColumnDefinitions>
            <FontIcon Grid.Column="0" FontSize="16" Glyph="&#xE1E0;" VerticalAlignment="Center" HorizontalAlignment="Center"/>
            <StackPanel Grid.Column="1" Orientation="Vertical">
                <TextBlock Style="{ThemeResource BodyTextBlockStyle}" Text="!!!TEXT HERE PROGRAMATICALLY!!!" Foreground="{StaticResource MainColorBrush}" FontSize="13" VerticalAlignment="Center" />
                <TextBlock Style="{ThemeResource BodyTextBlockStyle}" Text="{StaticResource LogoutButtonText}" VerticalAlignment="Center" />
            </StackPanel>
        </Grid>
    </Setter.Value>
</Setter>

你可以破解，更改行：

<TextBlock Style="{ThemeResource BodyTextBlockStyle}" Text="!!!TEXT HERE PROGRAMATICALLY!!!" Foreground="{StaticResource MainColorBrush}" FontSize="13" VerticalAlignment="Center" />

到

<TextBlock Style="{ThemeResource BodyTextBlockStyle}" Text="{Binding Tag}" Foreground="{StaticResource MainColorBrush}" FontSize="13" VerticalAlignment="Center" />

并在代码中设置按钮的 Tag 属性。

正确的做法是声明新的 DependencyProperty 类型的 CustomButton 字符串，它继承自 Button。然后将 Style 应用于新的 CustomButton 类型。将 Text 属性绑定到新创建的 DependencyProperty
