棱镜导航到另一个视图
本文关键字:视图 另一个 导航 棱镜 | 更新日期: 2023-09-27 18:15:56
我有一个主窗口,它只包含用于显示其他视图的区域:
<ContentControl Grid.Row="1" prism:RegionManager.RegionName="ContentRegion"/>
我想做的是,当我的MainWindowViewModel
加载时,立即导航到MainPageViewModel
。
我已经尝试实现接口INavigationAware
,如:
public void OnNavigatedTo(NavigationContext navigationContext)
{
_regionManager.RequestNavigate("ContentRegion", App.Experiences.DetailPage.ToString());
}
public bool IsNavigationTarget(NavigationContext navigationContext)
{
return true;
}
public void OnNavigatedFrom(NavigationContext navigationContext)
{
_regionManager.RequestNavigate("ContentRegion", App.Experiences.DetailPage.ToString());
}
但是即使我在上面设置了断点,它们也不会被执行。
我做错了什么?
编辑
也许我需要改变我的Bootstrapper逻辑?下面是它的样子:
public class Bootstrapper: UnityBootstrapper
{
protected override System.Windows.DependencyObject CreateShell()
{
return Container.TryResolve<MainWindow>();
}
protected override void InitializeShell()
{
Application.Current.MainWindow.Show();
}
protected override void ConfigureContainer()
{
base.ConfigureContainer();
Container.RegisterType(typeof(IDataRepository), typeof(DataRepository), null,new Microsoft.Practices.Unity.ContainerControlledLifetimeManager());
Container.RegisterTypeForNavigation<MainPage>(App.Experiences.MainPage.ToString());
Container.RegisterTypeForNavigation<DetailPage>(App.Experiences.DetailPage.ToString());
}
}
我必须编辑我的Bootstrapper逻辑,如下所示:
protected override void InitializeShell()
{
Application.Current.MainWindow.Show();
Prism.Regions.IRegionManager newRegion = Container.TryResolve<Prism.Regions.IRegionManager>();
newRegion.RequestNavigate("ContentRegion", App.Experiences.MainPage.ToString());
}
