Silverlight在父页面中弹出子页面

首先创建一个Silverlight项目，紧接着创建Silverlight子窗体，命名为MyChildWindow.xaml

先看一下MainPage.xaml界面：

子页面MyChildWindow.xaml界面：

MainPage.xaml具体实现：

 <Grid x:Name="LayoutRoot" Background="White">
2         <Button Content="显示子窗口" Height="23" Click="ShowWindow_Click" Margin="0,138,248,138" />
3         <sdk:Label Height="28" HorizontalAlignment="Left" Margin="10,10,0,0" Name="message" VerticalAlignment="Top" Width="120" />
4 </Grid>

MainPage.xaml.cs:

 1 public partial class MainPage : UserControl
 2 {
 3     MyChildWindow myChildWindow = new MyChildWindow();
 4     public MainPage()
 5     {
 6        InitializeComponent();
 7        myChildWindow.Closed += new EventHandler(myChildWindow_Closed);
 8     }
 9     void myChildWindow_Closed(object sender, EventArgs e)
10     {
11        if (myChildWindow.DialogResult == true)
12           message.Content = string.Format("用户名：{0},密码:{1}", myChildWindow.UserName.Text, myChildWindow.PassWord.Text);
13        else
14           message.Content = "";
15     }
16      //显示子窗体
17     private void ShowWindow_Click(object sender, RoutedEventArgs e)
18     {
19        myChildWindow.Title = "显示子窗体";
20        myChildWindow.OverlayBrush = new SolidColorBrush(Colors.Yellow);
21        myChildWindow.Opacity = 0.9;
22        myChildWindow.HasCloseButton = true;
23        myChildWindow.Foreground = new SolidColorBrush(Colors.Red);
24        myChildWindow.FontSize = 14;
25        myChildWindow.Show();
26     }
27 }

 子窗口MyChildWindow.xaml代码

 1 <Grid x:Name="LayoutRoot" Background="White">
 2         <Grid.ColumnDefinitions>
 3             <ColumnDefinition Width="100"/>
 4             <ColumnDefinition Width="300"/>
 5         </Grid.ColumnDefinitions>
 6 
 7         <Grid.RowDefinitions>
 8             <RowDefinition Height="50"/>
 9             <RowDefinition Height="50"/>
10             <RowDefinition Height="50"/>
11         </Grid.RowDefinitions>
12 
13         <TextBlock Text="用户名:" Grid.Column="0" Grid.Row="0" />
14         <TextBox Width="200" x:Name="UserName" Grid.Column="1" Grid.Row="0" Height="30"/>
15         <TextBlock Text="密码:" Grid.Column="0" Grid.Row="1"/>
16         <TextBox Width="200" x:Name="PassWord" Grid.Column="1" Grid.Row="1" Height="30"/>
17 
18         <StackPanel Grid.ColumnSpan="2" Orientation="Horizontal" HorizontalAlignment="Center" Grid.Row="2">
19             <Button Content="提交" Width="75" Height="25"  x:Name="Submit" Click="Submit_Click"/>
20             <Button Content="取消" Width="75" Height="25"  x:Name="Cancel" Click="Cancel_Click"/>
21         </StackPanel>
22 </Grid>

MyChildWindow.xaml.cs代码:

 1 public MyChildWindow()
 2 {
 3      InitializeComponent();
 4 }
 5 //提交
 6 private void Submit_Click(object sender, RoutedEventArgs e)
 7 {
 8      this.DialogResult = true;
 9 }
10 //取消
11 private void Cancel_Click(object sender, RoutedEventArgs e)
12 {
13      this.DialogResult = false;
14 }

OK，这样就可以弹出子窗口了。
