WPF日期选择器图标大小

Question

WPF日期选择器图标大小

5

我有一个像这样的 DatePicker:

<DatePicker Grid.Row="7" HorizontalAlignment="Left" FontSize="43" CalendarStyle="{StaticResource styleCalendar}"/>

问题是，增加日期选择器的字体大小不会调整图标大小，它仍然很小。

我已经搜索过，但找不到一个适当的方法只调整图标大小，或者这可能不是放大整个选择器的正确方式。

尝试将字体大小保留为默认值，并给它一个LayoutTransform（或者也许应该是RenderTransform——两种都试试；我在用手机）：<DatePicker ...etc... RenderTransformOrigin="0,0" /><LayoutTransform><ScaleTransform ScaleX="4" ScaleY="4" /></LayoutTransform></DatePicker> 这可能会通过插值来缩放图标，这看起来不太好，但试一下。 - 15ee8f99-57ff-4f92-890c-b56153

谢谢。它完成了任务。需要调整比例以匹配最终的宽度和高度，但至少有了一些东西。 - La bla bla

你是如何扩大日期选择器的文本框的？我已经搜索了很多链接，但仍然没有答案。 - Monzer Yaghi

最简单的方法是将DatePicker放入一个Viewbox中，并调整Viewbox的大小。因此，借鉴您的示例，您可以这样做：

<Viewbox Grid.Row="7" HorizontalAlignment="Left" Width="150">
    <DatePicker CalendarStyle="{StaticResource styleCalendar}"/>
</Viewbox>

如果增加或减少Viewbox.Width参数，您就可以调整DatePicker的大小。

对我来说，解决方案是将日历按钮放在一个视图框内。

<DatePicker...>
 
  <DatePicker.Resources>
    <Style TargetType="{x:Type Button}">
     <Setter Property="Template">
       <Setter.Value>
         <ControlTemplate TargetType="{x:Type Button}">
           <Viewbox>
             <ContentPresenter/>
           </Viewbox>
         </ControlTemplate>
       </Setter.Value>
     </Setter>
    </Style>
  </DatePicker.Resources>
 
</DatePicker>

对于那些不满足于Michael Repucci提供的简单答案的人来说，我更喜欢的“清洁”替代方案可以让你仅将图标包围在一个视口中。您可以右键单击要修改的元素，在xaml文件的设计面板上单击“修改模型”。这将带您进入元素的xaml代码。然后您需要定位要修改的部分。在这里，我只使用了ViewBox将包含图标的按钮包围起来，而不是整个控件。涉及到的部分几乎在底部。我添加了一些换行符以使其更加可见。
