《SilverLight2快速入门》之基本控件Calendar

Calendar控件在工具箱中有，但是奇怪的是在SDK中并没有相关说明，也许是我本地安装有问题。我联想ASP.NET和WindowsForm中Calendar控件的相关用法，简单试验了一下。

下面试验实现获取选择的日期值，和使Calendar显示指定的日期值。

XAML代码中用到了Canvas布局。

< UserControl xmlns:basics ="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls"     x:Class ="_51CTO.lesson02.Calendar"
         xmlns ="http://schemas.microsoft.com/winfx/2006/xaml/presentation"    
         xmlns:x ="http://schemas.microsoft.com/winfx/2006/xaml"    
         Width ="400" Height ="300" >
         < Canvas Background ="LightSteelBlue" >
                 < basics:Calendar Name ="Calendar1" Canvas.Top ="0" Canvas.Left ="0"    
                 SelectedDatesChanged ="Calendar_SelectedDatesChanged" > </ basics:Calendar >
                 < TextBox Name ="SelectedDate" Canvas.Top ="170" Canvas.Left ="0" Width ="100" > </ TextBox >
                 < Button Name ="SetDate" Content ="设置"     Canvas.Top ="170" Canvas.Left ="110" Width ="50" Click ="Button_Click" > </ Button >
         </ Canvas >
</ UserControl >

C#代码如下，分别就选择日期和设置按钮点击实现：

namespace _51CTO.lesson02
{
         public partial class Calendar : UserControl
        {
                 public Calendar()
                {
                        InitializeComponent();
                }

                 private void Calendar_SelectedDatesChanged( object sender, SelectionChangedEventArgs e)
                {
                        SelectedDate.Text=String.Format( "{0:yyyy-MM-dd}",Calendar1.SelectedDate);
                }

                 private void Button_Click( object sender, RoutedEventArgs e)
                {
                        Calendar1.IsTodayHighlighted = true;
                        Calendar1.DisplayDate = DateTime.Parse(SelectedDate.Text);
                        Calendar1.SelectedDate = DateTime.Parse(SelectedDate.Text);
                }
        }
}

效果图如下：

点击设置按钮可以根据文本框中输入的日期来切换Calendar显示。
