设置备忘录以及设置界面

设置备忘录界面

同待办事项，相关名字改掉，类tododto改成memodto即可

添加文件

./Views/SkinView.xaml

./Views/SysSetView.xaml

./Views/AboutView.xaml

./ViewModels/SkinViewModel.cs

./ViewModels/SysSetViewModel.cs

./ViewModels/AboutViewModel.cs

添加子区域

添加变量

  • PrismManager.cs

    public static readonly string SettingsViewRgionName = "SettingsViewRgion";
注册区域

  • SettingsView.xaml

    <ContentControl prism:RegionManager.RegionName="{x:Static ext:PrismManager.SettingsViewRgionName}" />

SettingsView.xaml

从MainView.xaml处复制过来

            NavigateCmd = new DelegateCommand<MenuBar>(Navigate);
        }

        #region 菜单栏绑定变量定义以及初始化

    }
}

添加App.xaml，关联view和viewmodel

//建立view与viewmodel的关系
protected override void RegisterTypes(IContainerRegistry containerRegistry)
{
    containerRegistry.RegisterForNavigation<AboutView, AboutViewModel>();
    containerRegistry.RegisterForNavigation<SysSetView, SysSetViewModel>();
    containerRegistry.RegisterForNavigation<SkinView, SkinViewModel>();
    containerRegistry.RegisterForNavigation<IndexView, IndexViewModel>();
    containerRegistry.RegisterForNavigation<TodoView, TodoViewModel>();
    containerRegistry.RegisterForNavigation<MemoView, MemoViewModel>();
    containerRegistry.RegisterForNavigation<SettingsView, SettingsViewModel>();
}

编辑skinview

skinview.xaml

主要从materialDesignDemo项目复制，需要更改项目名称，引用空间，另需要添加转换器以及对应的转换器资源key
