本章讲述：日历模板改写
先来看看效果图：
1、头部按钮模板改写：按钮背景颜色透明，移动到按钮上，前景色改变
<Style TargetType="{x:Type Button}" x:Key="CalendarButton">
<Setter Property="Margin" Value="2"/>
<Setter Property="Foreground" Value="#FF333333" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Grid>
<ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"
VerticalAlignment="{TemplateBinding VerticalContentAlignment}" RecognizesAccessKey="True" />
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" Value="#FF0E8BD2" />
<Setter Property="Foreground" Value="White" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>

3、键值生成，设置日历控件为全局引用
<Style TargetType="{x:Type Calendar}" BasedOn="{StaticResource CalendarBaseStyle}"/>
4、外部引用
<Calendar Margin="32" SelectionMode="MultipleRange" SelectedDate="{ Binding CalendarTime}"/>
5、获取日历时间属性
private DateTime calendarTime;
public DateTime CalendarTime
{
get { return calendarTime; }
set
{
calendarTime = value;
NotifyOfPropertyChange(() => CalendarTime);
}
}
