《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。
