ToggleButton 不填满区域（windows phone）

Question

当我创建 ToggleButton 时，它不会填充网格中的所有区域。我认为这是因为按下区域不仅仅是按钮的可视区域。我怎样才能使这些区域相等？

    <Grid Grid.Column="0">
        <ToggleButton x:Name="ToggleHorizontal"
                      IsChecked="False"/>

    </Grid>

Answer 1

默认情况下，切换按钮（不仅如此）在可见边框周围有触摸区域，厚度为 12 像素（PhoneTouchTargetOverhang 常量，请参阅MSDN）。您可以通过在 Blend 中编辑切换按钮的样式来看到这一点。
因此，您可以将 XAML 中的边距值设置为 -12：

<Grid Grid.Column="0">
    <ToggleButton x:Name="ToggleHorizontal" Margin="-12"
                  IsChecked="False"/>

</Grid>

或者您可以在切换按钮样式中将此常量更改为 0。
Margin="{StaticResource PhoneTouchTargetOverhang}"
致
Margin="0"

希望我正确理解你的问题，我的回答会有所帮助

UPD：我认为将保证金值直接设置到切换按钮更容易，但如果您愿意...
将此添加到页面中的资源部分，不要忘记为切换按钮设置样式：

现在还有你的 ToggleButton：

<Grid Grid.Column="0">
    <ToggleButton x:Name="ToggleHorizontal" Margin="-12" Style="{StaticResource ToggleButtonStyle}"
                  IsChecked="False"/>

</Grid
