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

在我的UWP应用中有一个 CalendarDatePicker 控件。我无法使用 FontSize 属性选择日期的字体大小。

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.

如何在不覆盖很多样式的情况下轻松地做到这一点？

这是我拥有的基本代码：

Here is the basic code I have:

<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>

无论我设置的大小为 FontSize CalendarDatePicker 属性，所选日期的字体大小不会增加。

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

请帮助！

推荐答案

您可以使用Live Visual Tree工具检查控件的属性，在这种情况下，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le 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，它在默认模板中被硬编码为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" />
