[C#] WPF的DatePicker的日曆放大

第一天

這是我在寫C#時候使用DatePicker遇到的問題：

「日曆上的字太小了」

可是經過一番嘗試
還是找不到FontSize之類的Attribute去把它放大

最後發現需要使用<DatePicker CalendarStyle="xxx"> 並另外設定日曆風格來設定日曆的大小。

設定Style，並命名這個風格為 "styleCalendar"

<Style x:Key="styleCalendar" TargetType="{x:Type Calendar}">

    <Setter Property="Template">

        <Setter.Value>

            <ControlTemplate TargetType="{x:Type Calendar}">

                <!-- Wrapping in ViewBox will enlarge calendar of that size.-->

                <Viewbox Height="400"

                         Width="400">

                    <CalendarItem x:Name="PART_CalendarItem"

                                  Background="{TemplateBinding Background}"

                                  BorderBrush="{TemplateBinding BorderBrush}"

                                  BorderThickness="{TemplateBinding BorderThickness}"/>

                </Viewbox>

            </ControlTemplate>

        </Setter.Value>

    </Setter>

</Style>

在我們的DatePicker上加入CalendarStyle

<DatePicker CalendarStyle="{StaticResource styleCalendar}" Height="25" HorizontalAlignment="Left" Name="datePicker1" Width="115" />
