我添加了UWP日历日期选择器。这是XAML代码
<CalendarDatePicker Background="White" Grid.Row="6" Width="660" VerticalAlignment="Stretch" FontSize="48" PlaceholderText="Date of Birth" Padding="0" Margin="0" x:Name="DobDatePicker"></CalendarDatePicker>
但是问题是我无法更改日历文本块控件的高度（而不是弹出窗口）。我尝试通过设置最小高度来实现，但是它不起作用。有什么办法可以解决这个问题？
答案 0 :(得分：2)
CalenderDatePicker具有默认样式的行定义的硬编码值（32）。因此，您可以修改 CalenderDatePicker 默认样式的特定部分以更改高度。
//要修改的部分
<Style TargetType="CalendarDatePicker">
....
....
<Grid x:Name="Root">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="32" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="32" /> /* change your value */
</Grid.RowDefinitions>
....
....
</Style>
