【问题描述】:
最后,我决定加入 WPF 潮流,并决定遵循 MVVM 模式来创建我的应用程序。我也在使用 Caliburn.Micro。
我发现了许多将数据绑定到 Windows 的示例,但所有示例都只包含一个 MainWindow。打开第二个和第三个窗口时,我不知道如何引用和进行绑定。为了说明我的问题,我创建了一个简单的应用程序。此应用程序有两个窗口,主窗口名为 ShellView,第二个窗口名为 Window1View。在这个应用程序中,我只需要将 myStr1 的内容显示到 Window1View 上的 TextBox 中。
代码如下:
Views.ShellView.xaml
<Window x:Class="Test.Views.ShellView"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525">
<Grid>
<TextBlock x:Name="Title" />
<Button Content="Window 1" Height="31" HorizontalAlignment="Left" Margin="24,268,0,0" Name="btnWin1" VerticalAlignment="Top" Width="87" Click="btnWin1_click" />
</Grid>
</Window>
Views.ShellView.xaml.cs
namespace Test.Views
{
using System.Windows;
public partial class ShellView : Window
{
public ShellView()
{
InitializeComponent();
}
private void btnWin1_click(object sender, RoutedEventArgs e)
{
Window1View win1 = new Window1View();
win1.Show();
}
}
}
ViewModels.ShellViewModel.cs
namespace Test.ViewModels
{
using Caliburn.Micro;
public class ShellViewModel : PropertyChangedBase
{
public static string txt1 = "String 1";
public static string txt2 = "String 2";
private string title;
public string Title
{
get { return title; }
set
{
if (title != value)
{
title = value;
RaisePropertyChangedEventImmediately("Title");
}
}
}
public ShellViewModel()
{
Title = "Hello Caliburn.Micro";
}
}
}
Views.Window1View.xaml
<Window x:Class="Test.Views.Window1View"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:c="clr-namespace:Caliburn.Micro;assembly=Caliburn.Micro"
Title="Window 1" Height="300" Width="300">
<Grid>
<Label Content="TextBox 1" Height="26" HorizontalAlignment="Left" Margin="12,40,0,0" Name="label1" VerticalAlignment="Top" Width="75" />
<TextBox Height="29" HorizontalAlignment="Left" Margin="106,39,0,0" Name="txtBox1" VerticalAlignment="Top" Width="145" Text="{Binding myStr1}" />
</Grid>
</Window>
View.Window1View.xaml.cs
using System.Windows;
namespace Test.Views
{
/// <summary>
/// Interaction logic for Window1View.xaml
/// </summary>
public partial class Window1View : Window
{
public Window1View()
{
InitializeComponent();
}
}
}
ViewModels.Window1ViewModel.cs
namespace Test.ViewModels
{
class Window1ViewModel
{
public Window1ViewModel()
{
myStr1 = ShellViewModel.txt1;
}
public string myStr1 { get; set; }
}
}
Bootstrapper.cs
namespace Test
{
public class Bootstrapper : Caliburn.Micro.Bootstrapper<Test.ViewModels.ShellViewModel>
{
}
}
App.xaml
<Application
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
x:Class="Test.App">
<Application.Resources>
</Application.Resources>
</Application>
App.xaml.cs
namespace Test
{
using System.Windows;
public partial class App : Application
{
Bootstrapper bootstrapper;
public App()
{
bootstrapper = new Bootstrapper();
}
}
}
对此的任何帮助将不胜感激。
谢谢
