有关Silverlight Calendar组件（日历组件）的研究——Silverlight学习笔记（1）

组件所在命名空间：

System.Windows.Controls

组件常用属性：

SelectedDate：获取或设置当前被选中的日期

DisplayDate：获取或设置日期以显示

DisplayDateStart：获取或设置被显示的第一个日期

DisplayDateEnd：获取或设置被显示的最后一个日期

SelectionMode：获取或设置Calendar组件的选取模式

None：设置日历为不可选

SingleDate：只能选择单一日期

SingleRange：只能连续选取日期

MultipleRange：能连续或者间隔地（通过按住Ctrl键）选取日期

BlackoutDates：获取或设置被标记为不可选的一个日期集合

SelectedDates：获取被选中的一个日期集合

IsTodayHighlighted：是否将今日日期高亮显示。

组件常用事件：

DisplayDateChanged：显示日期改变

DisplayModeChanged：显示模式改变

SelectedDatesChanged：被选中日期改变

实例：

说明：在属性方面应当重点掌握该组件的BlackoutDates和SelectedDates属性（可用于数据库的交互），在事件方面应当重点掌握SelectedDatesChanged事件。

效果图：

[原始状态]

[显示日期范围]

[SingleRange]

[MultipleRange和BlackoutDates]

[背景图片和背景视频]
