• 【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>
