【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>
