Caliburn.Micro框架之Bindings

新建一个WPF项目,将其命名为Caliburn.Micro.BindingsDemo

其次安装Caliburn.Micro,安装Caliburn.Micro的同时也会安装Caliburn.Micro.Core

然后新建Views文件夹和ViewsModels文件夹,前者是放视图的,后者是放管理视图的VM

然后删掉MainWindow.xaml,是的就是删掉它,再删掉app.xaml里面的uri的引导页面,然后添加引导页面代码,如下

    <Application.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary>
                    <local:Bootstrapper x:Key="Bootstrapper" />
                </ResourceDictionary>
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Application.Resources>

 

然后添加类,命名为Bootstrapper,这个就是起到引导作用,放到根目录下,起到复用的作用,如下

在OnStartup中就是重写了引导页面的作用,引导的页面为ShellView。

Bootstrapper的代码如下

public class Bootstrapper : BootstrapperBase
    {
        private SimpleContainer container;
        public Bootstrapper()
        {
            Initialize();
        }
        protected override void Configure()
        {
            container = new SimpleContainer();
            container.Singleton<IWindowManager, WindowManager>();
            container.PerRequest<ShellViewModel>();
        }
        protected override void OnStartup(object sender, StartupEventArgs e)
        {
            DisplayRootViewFor<ShellViewModel>();
        }
        protected override object GetInstance(Type service, string key)
        {
            return base.GetInstance(service, key);
        }
        protected override IEnumerable<object> GetAllInstances(Type service)
        {
            return base.GetAllInstances(service);
        }
        protected override void BuildUp(object instance)
        {
            container.BuildUp(instance);
        }
    }

 

其次在ViewModels中分别新建ActivityBaseViewModel,MessageActivityViewModel,PhotoActivityViewModel,ShellViewModel这四个类

ShellViewModel的代码如下

 public class ShellViewModel : Screen
    {
        private ActivityBaseViewModel selectedActivity;

        public ShellViewModel()
        {
            Activities = new BindableCollection<ActivityBaseViewModel>
            {
                new MessageActivityViewModel("MessageOne"),
                new PhotoActivityViewModel("PhoneOne"),
                new MessageActivityViewModel("MessageTwo"),
                new PhotoActivityViewModel("PhoneTwo")
            };
        }

        public BindableCollection<ActivityBaseViewModel> Activities { get; }

        public ActivityBaseViewModel SelectedActivity
        {
            get { return selectedActivity; }
            set { Set(ref selectedActivity, value); }
        }
    }

 

 

紧接着往Views文件建视图,分别建MessageActivityView,PhotoActivityView,ShellView,三个视图,其中ShellView用Windows窗体级别,而MessageActivityView和PhotoActivityView都是UserControl级别,因为Page放不到Windows窗体中。

MessageActivityView视图如下

PhotoActivityView视图如下

ShellView视图如下

整个逻辑是这样,先把资源绑定到UserControl中,然后再把UserControl视图绑定到ShellView视图中,因为ShellView的视图级别是Windows的,所以是可以放UserControl。所以理一下,这篇文章讲的是绑定bindings,整个逻辑是非常的清晰的。所以看下运行后的结果

文章仅供学习参考,如有不对,请多多指教,谢谢各位看官。
