WPF学习日记——Window的DataContext绑定ViewModel

1、全局的ViewModel绑定:

    a)设定全局的ViewModel(App.xaml中): 

1 <Application x:Class="MyTest.App"2         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"3         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"4         xmlns:local="clr-namespace:MyTest"5         StartupUri="MainWindow.xaml">6     <Application.Resources>7     <local:MainViewModel x:Key="mainVM"/>8     </Application.Resources>9 </Application>

     b)绑定全局的ViewModel(MainWindow中):  

1 <Window x:Class="MyTest.MainWindow"
2 xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
3 xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
4 xmlns:local="clr-namespace:MyTest"
5 Title="MainWindow" Height="600" Width="850" WindowStartupLocation="CenterScreen"
6 DataContext="{DynamicResource mainVM}">
7 </Window>

2、单独的ViewModel绑定(MainWindow中):

1 <Window x:Class="MyTest.MainWindow"2         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"3         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"4         xmlns:local="clr-namespace:MyTest"5         Title="MainWindow" Height="600" Width="850" WindowStartupLocation="CenterScreen">6     <Window.DataContext>7         <local:MainViewModel/>8     </Window.DataContext>
9 </Window>
