WPF子窗体：ChildWindow

wpf的子窗体选择有很多种，如最常见的是项目新建窗体(Window)作为子窗体

，或者新建wpf用户控件(UserControl)。而其实利用Xceed.Wpf.Toolkit.dll 可以轻松布局如下：

WPF子窗体：ChildWindow

第一步：引用Xceed.Wpf.Toolkit.dll。

第二步：在XAML引用名称空间：

   xmlns:xctk="clr-namespace:Xceed.Wpf.Toolkit.Primitives;assembly=Xceed.Wpf.Toolkit"
        xmlns:wpf="clr-namespace:Xceed.Wpf.Toolkit;assembly=Xceed.Wpf.Toolkit"

第三步：布局，XAML如下：

<Window x:Class="ChildWindowDemo.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:xctk="clr-namespace:Xceed.Wpf.Toolkit.Primitives;assembly=Xceed.Wpf.Toolkit"
        xmlns:wpf="clr-namespace:Xceed.Wpf.Toolkit;assembly=Xceed.Wpf.Toolkit"
        Title="MainWindow" Height="500" Width="700">
    <Grid>
        <StackPanel HorizontalAlignment="Center" VerticalAlignment="Center">
            <Button Margin="5" Content="打开子窗体1" Height="40" Width="100" Click="btnOpenChildWindow1_Click"/>
            <Button Margin="5" Content="打开子窗体2" Height="40" Width="100" Click="btnOpenChildWindow2_Click"/>
        </StackPanel>
        <xctk:WindowContainer>
            <wpf:ChildWindow x:Name="childWindow1" WindowStartupLocation="Center" WindowState="Closed" Caption="子窗体1" Width="300" Height="300">
                <StackPanel>
                    <TextBlock Text="这是子窗体1" HorizontalAlignment="Center" VerticalAlignment="Center"/>
                </StackPanel>
            </wpf:ChildWindow>
            <wpf:ChildWindow x:Name="childWindow2" WindowStartupLocation="Center" WindowState="Closed" Caption="子窗体2"  Width="500" Height="400">
                <StackPanel>
                    <TextBlock Text="这是子窗体2" HorizontalAlignment="Center" VerticalAlignment="Center"/>
                </StackPanel>
            </wpf:ChildWindow>
        </xctk:WindowContainer>
    </Grid>
</Window>
