Silverlight 4 新特性之NotificationWindow-优快云博客

Silverlight4 中增加很多新特性. 相对于Silverlight 3 有了更加丰富运用. 当然对于用户而言也就有了更多的选择. 最近在更新 Silverlight 3版本时项目中关于消息通知的功能. . 原来项目中运用一个很成熟的JS库来实现消息通知. 样式比较单一. 而且更改起来比较麻烦. 而Silverlight 4 NotificationWindow 的出现则大大简化这个调用流程 .实现效果如下:

A:Silverlight 4 NotificationWindow 只在OOB模式下支持装载本地:

B:运行效果:

C:输入认识字符点击Button按钮在屏幕右下角:

实现步骤:

<1>页面布局-[很简单]:

<Grid x:Name="LayoutRoot" Background="White" HorizontalAlignment="Center" VerticalAlignment="Center">
<TextBox Height="68" HorizontalAlignment="Left" Margin="12,75,0,0" Name="textBox1" VerticalAlignment="Top" Width="441" TextWrapping="Wrap" IsTabStop="True" FontSize="12" />
<Button Content="Give me The Message" Foreground="Red" Background="Red" Height="50" HorizontalAlignment="Left" Margin="488,84,0,0" Name="SendMessage" VerticalAlignment="Top" Width="151" />
<TextBlock Height="35" HorizontalAlignment="Left" Margin="31,23,0,0" Name="textBlock1" Text="Silverlight4 -NotificationWindow " VerticalAlignment="Top" Width="336" Foreground="Red" FontFamily="Lucida Sans Unicode" FontSize="20" />
</Grid>

<2>后台编码:

public MainPage()
{
InitializeComponent();
//绑定事件
this.SendMessage.Click += new RoutedEventHandler(SendMessage_Click);
}
void SendMessage_Click(object sender, RoutedEventArgs e)
{
//首先检测是否Application 在OOB状态
if (Application.Current.IsRunningOutOfBrowser)
{
NotificationWindow newwindow = new NotificationWindow();
newwindow.Height = 100;
newwindow.Width = 400;
newwindow.Closed += new EventHandler(newwindow_Closed);
//设置内容
TextBlock msgblock = new TextBlock { Text = this.textBox1.Text, FontSize = 12};
//尝试一下展示图片
Image img = new Image();
img.Source = new BitmapImage(new Uri("../Images/danzeer.jpg", UriKind.RelativeOrAbsolute));
img.Width = 50;
img.Height = 50;
Grid contentgrid = new Grid();
//contentgrid.VerticalAlignment = VerticalAlignment.Top;
//contentgrid.HorizontalAlignment = HorizontalAlignment.Left;
contentgrid.Children.Add(msgblock);
contentgrid.Children.Add(img);
newwindow.Content = contentgrid;
//展示
newwindow.Show(5000);//展示3秒钟
}
else
{
MessageBox.Show("尚未初始化为OOB模式！");
}
}
void newwindow_Closed(object sender, EventArgs e)
{
MessageBox.Show("这是我的关闭事件！");
}
