WPF中的ChildWindow----WPF的toolkit使用

Silverlight中有ChildWindow这个东西，上午想起来WPF中是否也有这个东西呢？
其实如果真用代码也是可以实现ChildWindow，可是有没有更便捷的方法呢？我想到了WPF的toolkit，发现新的版本中还真是有这么个控件。首先声明，这里是个控件，这个Silverlight里面的ChildWindow的实现方式不一样，Silverlight中如何实现不再赘述。因为silverlight中的childwindow的固定思维使对这个东西的使用走了弯路，迷惑了好一会，所以分享给大家。

首先需要下载wpftoolkit和Extended WPF Toolkit Binaries。然后在项目中添加对WPFToolkit和WPFToolkit.Extended的引用：

在wpf窗口的<Window 节点中添加对命名空间的引用，加入一行

  
  

   
   xmlns:extToolkit="clr-namespace:Microsoft.Windows.Controls;assembly=WPFToolkit.Extended" 
  
  

然后在页面中添加一个childwindow控件，

  
  

   
   <extToolkit:ChildWindow x:Name="childWindow" Visibility="Hidden" Caption="My Child Window" Width="456" Closed="childWindow_Closed" IsModal="True" Height="253">
   
   
 
   
   <Grid Margin="10" >
   
    
<StackPanel Orientation="Horizontal" Margin="8,8,0">
   
   
 
   
   <StackPanel.Background>
   
   
 
   
   <LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
   
   
 
   
   <GradientStop Color="#FFF4F8FF" Offset="0"/>
   
   
 
   
   <GradientStop Color="White" Offset="1"/>
   
   
 
   
   </LinearGradientBrush>
   
   
 
   
   </StackPanel.Background>
   
   
 
   
   <Button Width="65" Margin="100,76.5,2,0" x:Name="okbtn" Click="okbtn_Click" Content="获取值" Height="40" RenderTransformOrigin="-0.354,0.525" VerticalAlignment="Top" d:LayoutOverrides="Height"/>
   
   
 
   
   <Button Width="65" Margin="50,0" x:Name="cancalbtn" Click="cancalbtn_Click" Content="设置值" Height="40" VerticalAlignment="Top" d:LayoutOverrides="Height"/>
   
   
 
   
   </StackPanel>
   
   
 
   
   </Grid>
   
   
 
   
   </extToolkit:ChildWindow>
  
  

然后在后台就可以对这个控件进行操作了，

  
  

   
    private void OpenChildWindow_Click(object
   
    sender,RoutedEventArgs e)
 {
 childWindow.Visibility =
   
    Visibility.Visible;
 childWindow.Show();
 }
  
  

现将截图如下：
