一．前言

　　申明：WPF自定义控件与样式是一个系列文章，前后是有些关联的，但大多是按照由简到繁的顺序逐步发布的等，若有不明白的地方可以参考本系列前面的文章，文末附有部分文章链接。

本文主要内容：

  • 日历控件Calendar自定义样式；
  • 日期控件DatePicker自定义样式，及Label标签、水印、清除日期功能扩展；

二．Calendar自定义样式

先看看效果：

技术分享

从上面图可以看出，日历的显示其实有三种状态，如下面的分解图：

  • "日"部分的显示；
  • "月"部分的显示；
  • "年"部分的显示；

因此一个完整的日历，就包含多个部分，首先是"日"按钮的样式：

    <!--Day按钮样式-->
    <Style x:Key="CalendarDayButtonStyle" TargetType="{x:Type CalendarDayButton}">
        <Setter Property="MinWidth" Value="28" />

最后综合以上的样式，定义我们需要的Calendar样式就差一步之遥了。  

    <!--默认日历样式-->
    <Style x:Key="DefaultCalendar" TargetType="{x:Type Calendar}">
        <Setter Property="SnapsToDevicePixels" Value="True" />
        <Setter Property="Foreground" Value="{StaticResource TextForeground}" />
        <Setter Property="CalendarDayButtonStyle" Value="{StaticResource CalendarDayButtonStyle}" />
        <Setter Property="CalendarItemStyle" Value="{StaticResource CalendarItemStyle}" />
        <Setter Property="CalendarButtonStyle" Value="{StaticResource CalendarButtonStyle}" />
        <Setter Property="Background" Value="{StaticResource PopupBackground}" />
        <Setter Property="BorderBrush" Value="{StaticResource ControlBorderBrush}" />
        <Setter Property="BorderThickness" Value="1" />
        <Setter Property="FontSize" Value="13" />
        <Setter Property="FontFamily" Value="{StaticResource FontFamily}" />
        <Setter Property="IsTodayHighlighted" Value="True" />
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type Calendar}">
                    <StackPanel x:Name="PART_Root" HorizontalAlignment="Center" Background="Transparent">
                        <CalendarItem x:Name="PART_CalendarItem" BorderBrush="{TemplateBinding BorderBrush}" FontSize="{TemplateBinding FontSize}"
                                      FontFamily="{TemplateBinding FontFamily}"
                                      BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}"
                                      Style="{TemplateBinding CalendarItemStyle}" />
                    </StackPanel>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

 

三．DatePicker自定义样式，及Label标签、水印、清除日期功能扩展

　　有了上面的日历样式，下面做DatePicker的样式就好办了，其实就是TextBox+Button+Calendar。此处的实现同上一篇（WPF自定义控件与样式(3)-TextBox & RichTextBox & PasswordBox样式）思路基本一致，因此本文就不做更多的解释，可以参考本系列前面的文章（末尾附录有链接）先看看效果图：

使用示例： 

            <DatePicker Margin="3" core:ControlAttachProperty.Watermark="妈的快输入日期"/>
            <DatePicker Margin="3" SelectedDate="{x:Static system:DateTime.Today}"/>
            <DatePicker Margin="3" IsEnabled="False" SelectedDate="{x:Static system:DateTime.Today}"/>

3.2 Label标签

通过扩展基础样式中的标签附加属性实现，定义样式代码：  

    <!--DatePicker包含附加属性Label的样式 LabelDatePicker -->
    <Style TargetType="{x:Type DatePicker}" x:Key="LabelDatePicker" BasedOn="{StaticResource DefaultDatePicker}">
        <Setter Property="Width" Value="260"></Setter>
        <Setter Property="local:ControlAttachProperty.LabelTemplate" >
            <Setter.Value>
                <ControlTemplate TargetType="ContentControl">
                    <Border Width="60" Background="{StaticResource TextLabelBackground}">
                        <TextBlock VerticalAlignment="Center" HorizontalAlignment="Right" Margin="2" Text="{TemplateBinding Content}"></TextBlock>
                    </Border>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

使用示例：  

<DatePicker Margin="3" Style="{StaticResource LabelClearButtonDatePicker}" core:ControlAttachProperty.Watermark="选择出生日期" core:ControlAttachProperty.Label="出生日期"/>
<DatePicker Margin="3" Style="{StaticResource LabelDatePicker}" core:ControlAttachProperty.Label="死亡日期" SelectedDate="{x:Static system:DateTime.Today}"/>
<DatePicker Margin="3" Style="{StaticResource LabelDatePicker}" core:ControlAttachProperty.Label="非法日期" IsEnabled="False" SelectedDate="{x:Static system:DateTime.Today}"/>

3.3 清除日期值的功能扩展

此功能在前面的文章有介绍过（参考本文末尾链接），效果在上面的图片中可以看到。样式代码：  

    <!--DatePicker包含清除Text按钮的样式 ClearButtonDatePicker -->
    <Style TargetType="{x:Type DatePicker}" x:Key="ClearButtonDatePicker" BasedOn="{StaticResource DefaultDatePicker}">
        <Setter Property="local:ControlAttachProperty.AttachContent">
            <Setter.Value>
                <ControlTemplate>
                    <local:FButton FIcon="&#xe60a;" Style="{StaticResource FButton_Transparency}" IsTabStop="False" FIconMargin="0"
                                   local:ControlAttachProperty.IsClearTextButtonBehaviorEnabled="True" Command="local:ControlAttachProperty.ClearTextCommand" 
                                   CommandParameter="{Binding RelativeSource={RelativeSource FindAncestor,AncestorType={x:Type DatePicker}}}"
                               Margin="1,3,0,4" FIconSize="14" Foreground="{StaticResource TextForeground}" Cursor="Arrow"/>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

    <!--DatePicker包含附加属性Label，以及ClearText按钮的样式 LabelClearButtonDatePicker -->
    <Style TargetType="{x:Type DatePicker}" x:Key="LabelClearButtonDatePicker" BasedOn="{StaticResource DefaultDatePicker}">
        <Setter Property="Width" Value="280"></Setter>
        <Setter Property="local:ControlAttachProperty.LabelTemplate" >
            <Setter.Value>
                <ControlTemplate TargetType="ContentControl">
                    <Border Width="60" Background="{StaticResource TextLabelBackground}">
                        <TextBlock VerticalAlignment="Center" HorizontalAlignment="Right" Margin="2" Text="{TemplateBinding Content}"></TextBlock>
                    </Border>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
        <Setter Property="local:ControlAttachProperty.AttachContent">
            <Setter.Value>
                <ControlTemplate>
                    <local:FButton FIcon="&#xe60a;" Style="{StaticResource FButton_Transparency}" IsTabStop="False" FIconMargin="0"
                               local:ControlAttachProperty.IsClearTextButtonBehaviorEnabled="True" Command="local:ControlAttachProperty.ClearTextCommand" 
                               CommandParameter="{Binding RelativeSource={RelativeSource FindAncestor,AncestorType={x:Type DatePicker}}}"
                               Margin="0,3,0,4" FIconSize="14" Foreground="{StaticResource TextForeground}" Cursor="Arrow"/>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

使用示例：  

<DatePicker Margin="3" Style="{StaticResource ClearButtonDatePicker}"/>
<DatePicker Margin="3" Style="{StaticResource LabelClearButtonDatePicker}" core:ControlAttachProperty.Watermark="选择出生日期" core:ControlAttachProperty.Label="出生日期"/>
