如何增加在 CalendarDatePicker 上选择的日期的字体大小 [英] How to increase the font size of the date that is selected on a CalendarDatePicker

问题描述

我的 UWP 应用上有一个 CalendarDatePicker 控件.我无法增加使用 FontSize 属性选择的日期字体的大小.

I have a CalendarDatePicker control on my UWP app. I am not able to increase the size of the font of the date that is selected using the FontSize attribute.

如何在不覆盖大量样式的情况下轻松完成此操作?

这是我的基本代码:

<Page
    x:Class="CalendarPickerExample.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:CalendarPickerExample"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d">

    <Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
        <CalendarDatePicker FontSize="30" />
    </Grid>

</Page>

无论我在CalendarDatePicker上设置FontSize属性是什么大小，所选日期的字体大小都不会增加.

No matter what size I set the FontSize attribute on the CalendarDatePicker, the size of the font of the selected date does not increase.

请帮忙！

推荐答案

您可以使用 Live Visual Tree 工具检查控件的属性，如果您想更改内部 TextBlock 的大小:

You can check the properties of the control using Live Visual Tree tool, in your case you want to change the size of the internal TextBlock:

您可以在默认样式的副本中修改 TextBlock 字体大小 https://msdn.microsoft.com/en-us/library/windows/apps/mt299110.aspx

You can modify the TextBlock font size in a copy of the default style https://msdn.microsoft.com/en-us/library/windows/apps/mt299110.aspx

如您所见，默认模板中硬编码为 15:

As you can see, it is hardcoded to 15 in the default template:

<TextBlock x:Name="DateText"
                   HorizontalAlignment="Left"
                   Foreground="{ThemeResource SystemControlForegroundBaseMediumBrush}"
                   Text="{TemplateBinding PlaceholderText}"
                   Grid.Row="1"
                   FontSize="15"
                   Padding="12, 0, 0, 2"
                   VerticalAlignment="Center" />
