【WPF/WAF】主界面（ShellWindow）引入别的界面布局

问题：主界面如果只用一个布局文件ShellWindow.xaml，会写得很大很臃肿。需要分为多个布局文件，然后由主界面引入。参考http://waf.codeplex.com/官方的BookLibrary案例，别人也是这么做的。

使用WPF Application Framework (WAF)框架新建的项目，将模板的分包结构如下：

需求：在主界面ShellWindow右侧是分页栏（TabControl），每个分页栏内容是一个单独的XAML布局文件。所以现在测试往主界面引入一个界面。完成后的效果应该是这样的：

根据WAF项目的结构，最后看起来是下下图那样，红框中是新增的文件。
由于篇幅有限，只提及几个关键点。完整流程点这里下载。

ShellWindow.xaml关键部分：

<!-- 右侧顶部分页栏/分组栏 -->
        <TabControl x:Name="tabControl" DockPanel.Dock="Top" Margin="410,0,10,0" Height="300" VerticalAlignment="Top">
            <TabItem Header="户型">
                <ScrollViewer VerticalScrollBarVisibility="Auto">
                    <ContentControl Name="HouseTypeView" Content="{Binding ShellService.HouseTypeView}" Margin="10" Focusable="False"/>
                </ScrollViewer>
            </TabItem>
            ......

新建的分页栏某一页的布局HouseTypeView.xaml：

<UserControl 
        x:Class="WafApplication1.Presentation.Views.HouseTypeView"

    <DockPanel Margin="10" >
        <StackPanel Orientation="Vertical">
            <Grid Margin="10" Height="40" >
                <!-- 定义列宽 -->
                <Grid.ColumnDefinitions>
                    <!-- 第一列 -->
                    <ColumnDefinition Width="100"/>
                    <!-- 第二列 -->
                    <ColumnDefinition Width="200"/>
                    <!-- 第三列 -->
                    <ColumnDefinition Width="auto"/>
                </Grid.ColumnDefinitions>
                <Grid.RowDefinitions>
                    <RowDefinition Height="auto"/>
                </Grid.RowDefinitions>

                <!-- 第一行第一列 -->
                <ComboBox Grid.Column="0" Grid.Row="0" x:Name="cityComboxBox" Margin="50,10,0,200" Height="20"/>

                <!-- 第一行第三列 -->
                <Button Grid.Column="2" Grid.Row="0" x:Name="searchBtn" Command = "{Binding AlertCommand}" Content="搜 索" VerticalAlignment="Center" Width="50" Height="20" Background="#0094ff" Margin="10,10,0,200"/>
            </Grid>
            <Grid Height="100">
                <StackPanel Orientation="Horizontal" Margin="10, 10, 10, 10">
                    <TextBlock Text="热门搜索 :" FontSize="10" Margin="70,5,20,62" HorizontalAlignment="Center" />
                    <WrapPanel Orientation="Horizontal" Width="250">
                        <TextBox Text="A社区" Margin="5" />
                        <TextBox Text="A社区" Margin="5" />
                        <TextBox Text="A社区" Margin="5" />
                        <TextBox Text="A社区" Margin="5" />
                        <TextBox Text="A社区" Margin="5" />
                        <TextBox Text="A社区" Margin="5" />
                        <TextBox Text="A社区" Margin="5" />
                        <TextBox Text="A社区" Margin="5" />
                    </WrapPanel>
                </StackPanel>
            </Grid>
        </StackPanel>
    </DockPanel>
</UserControl>

HouseTypeView.xaml.cs主要是做两个ComboBox下拉菜单的级联：

using System;
using System.Collections;
using System.Collections.Generic;
using System.ComponentModel.Composition;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Media;
using WafApplication1.Applications.Views;
using WafApplication1.Applications.ViewModels;

namespace WafApplication1.Presentation.Views
{
    [Export(typeof(IHouseTypeView))]
    public partial class HouseTypeView : UserControl, IHouseTypeView
    {
        private Dictionary<string, string[]> cityAndCommunityDictionary = new Dictionary<string, string[]>()
        {
            { "南宁", new string[] { "南宁A社区", "南宁B社区", } },
            { "柳州", new string[] { "柳州A社区", "柳州B社区", "柳州C社区", "柳州D社区" } },
            { "桂林", new string[] { "桂林A社区", "桂林B社区", "桂林C社区" } },
        };

        public HouseTypeView()
        {
            InitializeComponent();
            // 初始化两个下拉列表
            InitComboBox();
        }


        /// <summary>
        /// 初始化选择城市的下拉列表
        /// </summary>
        private void InitComboBox()
        {
            // 初始化城市列表
            ItemCollection coll = cityComboxBox.Items;
            foreach (KeyValuePair<string, string[]> kvp in cityAndCommunityDictionary)
            {
                ComboBoxItem boxItem = new ComboBoxItem() { Content = kvp.Key };
                coll.Add(boxItem);
            }

            // 给ComboBox注册一个选项改变的事件
            cityComboxBox.SelectionChanged += new SelectionChangedEventHandler(cityComboxBox_SelectionChanged);
        }

        private void cityComboxBox_SelectionChanged(object sender, SelectionChangedEventArgs e)
        {
            // 当前城市的社区
            ItemCollection coll = communityComboxBox.Items;
            // 先清空
            coll.Clear();
            // 再添加
            foreach (KeyValuePair<string, string[]> kvp in cityAndCommunityDictionary)
            {
                // kvp.Value = { "南宁A社区", "南宁B社区", }
                // 此时的 cityComboxBox.SelectedValue = System.Windows.Controls.ComboBoxItem: 南宁
                // 所以如果用这种方法获取选中的值，还需要切割字符串
                ComboBoxItem selectedCity = cityComboxBox.SelectedItem as ComboBoxItem;
                string cityName = selectedCity.Content.ToString();

                System.Console.WriteLine("cityName = " + cityName);
                if (cityName.Equals(kvp.Key))
                {
                    foreach (var item in kvp.Value)
                    {
                        // item = "南宁A社区"
                        ComboBoxItem boxItem = new ComboBoxItem() { Content = item };
                        coll.Add(boxItem);
                    }
                }
            }
        }
    }
}

在Applications/Controllers新建一个HouseTypeController.cs：

using System.ComponentModel.Composition;
using WafApplication1.Applications.Services;
using WafApplication1.Applications.ViewModels;

namespace WafApplication1.Applications.Controllers
{
    [Export]
    internal class HouseTypeController
    {
        private readonly IShellService shellService;
        private readonly HouseTypeViewModel houseTypeViewModel; // 引入

        [ImportingConstructor]
        public HouseTypeController(IShellService shellService, HouseTypeViewModel houseTypeViewModel)
        {
            this.shellService = shellService;
            this.houseTypeViewModel = houseTypeViewModel; // 构造传参引入
        }

        public void Initialize()
        {
            shellService.HouseTypeView = houseTypeViewModel.View; // 
        }

    }
}

修改Applications/Controllers/ApplicationControl.cs：

using System.ComponentModel.Composition;
using WafApplication1.Applications.Services;
using WafApplication1.Applications.ViewModels;

namespace WafApplication1.Applications.Controllers
{
    [Export]
    internal class ApplicationController
    {
        private readonly ShellService shellService;
        private readonly ShellViewModel shellViewModel;
        private readonly HouseTypeViewModel houseTypeViewModel;
        private readonly HouseTypeController houseTypeController;

        [ImportingConstructor]
        public ApplicationController(ShellViewModel shellViewModel, ShellService shellService, HouseTypeViewModel houseTypeViewModel, HouseTypeController houseTypeController)
        {
            this.shellViewModel = shellViewModel;
            this.shellService = shellService;
            this.houseTypeViewModel = houseTypeViewModel;
            this.houseTypeController = houseTypeController;
        }

        public void Initialize()
        {
            shellService.ShellView = shellViewModel.View;
            houseTypeController.Initialize();
        }

        public void Run()
        {
            shellViewModel.Show();
        }

        public void Shutdown()
        {
        }
    }
}
