3、Calendar.xaml

<!--
Calendar控件的命名空间和其他控件一样,都是在System.Windows.Controls下
但是其是在System.Windows.Controls.dll程序集中定义的
所以要引入相应的xml命名空间
-->
<UserControl x:Class="Silverlight20.Control.Calendar"
    xmlns
="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
    xmlns:x

    xmlns:basics
="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls">
    
<StackPanel HorizontalAlignment="Left">
        
<TextBox x:Name="txtMsg" Margin="5"  />
        
        
<!--
        SelectedDatesChanged - 选中日期后所触发的事件
        DisplayDateEnd - 此日期之后的日期不予显示 
        DisplayDateStart - 此日期之前的日期不予显示
        FirstDayOfWeek - 控件所显示的每星期的第一天为星期几 [System.DayOfWeek枚举]
        DisplayMode - 控件的显示模式 [System.Windows.Controls.DisplayMode枚举]
            DisplayMode.Month - 标题显示年月,内容显示日期。默认值
            DisplayMode.Year - 标题显示年,内容显示月
            DisplayMode.Decade - 标题显示一个十年的区间,内容显示年
        IsTodayHighlighted - 是否高亮显示今天的日期
