VB编写系统硬 件设备控制工具--DeviceControlContentControl 与 ViewModel （一） - E不小心 - 博客园
前阵子有人问我MVVM模式下，在View中嵌套View，切换View。想一想还是写下来吧。
主要就是用到 ContentControl 和 DataTemplate，这算是一种 ViewModel First 的思想吧。
其实好多MVVM的框架，也都提供这样的功能。在ContentControl绑定ViewModel，就可以显示 对应的View。比如&Caliburn.Micro(CM框架).
MVVMLight应该是没有提供的，对他我本身不是很熟，以前知道他很轻，看过原码，真心没有多少，最近在RT中用了下，发现它也加入了IOC的东东。
以下代码没用使用任何第三方框架。
using System.Windows.I
namespace ContentDemo
// ViewModelBase 只是实现了 INotifyPropertyChanged
class MainViewModel : ViewModelBase
{　　　　 // 如果有IOC这块的东西 可以用IOC代替。
private readonly FirstViewModel _firstViewModel = new FirstViewModel();
private readonly SecondViewModel _secondViewModel = new SecondViewModel();
private object _viewM
/// &summary&
/// 要绑定和切换的ViewModel
/// &/summary&
public object ViewModel
get { return _viewM }
if (_viewModel == value)
_viewModel =
OnPropertyChanged();
// 下面两个 Command只是为了 切换 ViewModel用的。
private ICommand _firstC
public ICommand FirstCommand
return _firstCommand = _firstCommand ?? new DelegateCommand(obj =&
ViewModel = _firstViewM
private ICommand _secondC
public ICommand SecondCommand
return _secondCommand = _secondCommand ?? new DelegateCommand(obj =&
ViewModel = _secondViewM
这个是ViewModel的代码，ViewModel OK啦，我们就来写View了。
&Window x:Class="ContentDemo.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:ContentDemo"
Title="MainWindow" Height="350" Width="525"&
&Window.Resources&
&local:MainViewModel x:Key="MainViewModel" /&
&DataTemplate DataType="{x:Type local:FirstViewModel}"&
&local:FirstView /&
&/DataTemplate&
&DataTemplate DataType="{x:Type local:SecondViewModel}"&
&local:SecondView /&
&/DataTemplate&
&/Window.Resources&
&Grid DataContext="{StaticResource MainViewModel}"&
&Grid.RowDefinitions&
&RowDefinition /&
&RowDefinition Height="Auto"/&
&/Grid.RowDefinitions&
&Grid.ColumnDefinitions&
&ColumnDefinition /&
&ColumnDefinition /&
&/Grid.ColumnDefinitions&
&ContentControl Grid.ColumnSpan="2" Content="{Binding Path=ViewModel}" /&
&Button Grid.Row="1" Grid.Column="0" Content="ViewModel
1" Command="{Binding Path=FirstCommand}"/&
&Button Grid.Row="1" Grid.Column="1" Content="ViewModel
2" Command="{Binding Path=SecondCommand}"/&
其实这也没什么，关键的地方就是，ContentControl的Content要绑定ViewModel，这是用来显示和切换ViewModel对应的View的。
在资源中加入DataTempalte，DataType设置成ViewModel的类型，DataTemplate 写上你的View，只样就可以自动匹配的你ViewModel啦。
注：在WinRT中的DataTemplate是没有DataType属性的，SL里有没有，我记不住了。可以用我最下面说的办法来弄。
下在是 二个ViewModel和View的代码，都很简答，就是为了展示一下。
class FirstViewModel
public string Content { get; set; }
public FirstViewModel()
Content = "第一个ViewModel";
class SecondViewModel
public string Content { get; set; }
public SecondViewModel()
Content = "第二个ViewModel";
&UserControl x:Class="ContentDemo.FirstView"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

这样，我们切换MailViewModel中的ViewModel的时候，就会换成不同的UI了，DataTemplate 中内容的DataContext 也会是相应的ViewModel。
写的很不好，我的语文虽然不是体育老师交的，也是数学老教交出来的。
还是直接源码吧：
源码是2013写的，打不开的自行修改 项目文件或复制源码到新项目吧。
可能现在有人发现了，这样每一个用到的ViewModel和都至少写上一个DataTemplate，这样很不爽，重复的代码太多啦。
下一步的关键就是 DataTemplateSelector。说到这个，大家可能就会了，下篇再分解吧。嘿嘿
