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：

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>

C#后台代码如下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;

namespace ChildWindowDemo
{
    /// <summary>
    /// MainWindow.xaml 的交互逻辑
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
        }

        private void btnOpenChildWindow1_Click(object sender, RoutedEventArgs e)
        {
            childWindow1.IsModal = true;//设置为模态窗口
            childWindow1.Show();
        }

        private void btnOpenChildWindow2_Click(object sender, RoutedEventArgs e)
        {
            childWindow2.IsModal = true;
            childWindow2.Show();
        }
    }
}

总结：有些简单的子窗体，例如要弹出一个列表窗口，而又不想去为此新建一个window,尝试使用ChildWindow，

以及用XAML绑定数据到相应的ChildWindow上，效果很不错
