wpf prism左侧抽屉式菜单

1.首先引入包MaterialDesignColors和MaterialDesignThemes

2.主页面布局

左侧菜单显示在窗体外，点击左上角菜单图标通过简单的动画呈现出来

3.左侧窗体外菜单

csharp 复制代码

<Grid x:Name="GridMenu" Width="150" HorizontalAlignment="Left" Margin="-150 0 0 0"  RenderTransformOrigin="0.5,0.5" Background="#4169E1">
    <Grid.RenderTransform>

        <ListView Foreground="White" FontFamily="Champagne &amp; Limousines" FontSize="18" ItemsSource="{Binding MenuList}">
            <ListView.ItemTemplate>
                <DataTemplate>
                    <StackPanel Orientation="Horizontal" Margin="0,10,0,0">
                        <Button Style="{DynamicResource MenuButtonStyle}"
                            Command="{Binding DataContext.ShowRegionCommand, RelativeSource={RelativeSource AncestorType={x:Type ListView}}}"
                            CommandParameter="{Binding ElementName=txtRegion}"/>
                        <TextBlock Text="{Binding Path = RegionName}" Visibility="Collapsed" Name="txtRegion"/>
                    </StackPanel>
                </DataTemplate>
            </ListView.ItemTemplate>
        </ListView>
    </StackPanel>
    <Button x:Name="ButtonClose" HorizontalAlignment="Right" VerticalAlignment="Top" Background="{x:Null}" Foreground="White" BorderBrush="{x:Null}" Width="30" Height="30" Padding="0">
        <materialDesign:PackIcon Kind="Close"/>
    </Button>
</Grid>

这里头像的图片写死了，需要的自己替换。

5.主页面事件

csharp 复制代码

<Window.Triggers>
    <EventTrigger RoutedEvent="ButtonBase.Click" SourceName="ButtonClose">
        <BeginStoryboard x:Name="CloseMenu_BeginStoryboard" Storyboard="{StaticResource CloseMenu}"/>
    </EventTrigger>
    <EventTrigger RoutedEvent="ButtonBase.Click" SourceName="ButtonOpen">
        <BeginStoryboard Storyboard="{StaticResource OpenMenu}"/>
    </EventTrigger>
</Window.Triggers>

6.主页面内容

csharp 复制代码

    <Grid x:Name="ContentGrid" HorizontalAlignment="Right" Width="1440">
        <Grid.RowDefinitions>
            <RowDefinition  Height="80"></RowDefinition>
            <RowDefinition></RowDefinition>
        </Grid.RowDefinitions>
        <Grid Background="#4169E1">
            <Grid x:Name="GridBackground" Background="#55313131" Opacity="0"/>
            <Button x:Name="ButtonOpen" HorizontalAlignment="Left" VerticalAlignment="Top" Background="{x:Null}" BorderBrush="{x:Null}" Width="30" Height="30" Padding="0">
                <materialDesign:PackIcon Kind="Menu" Foreground="#FF313131"/>
            </Button>
            <!--窗体控件按钮-->
            <StackPanel Orientation="Horizontal" VerticalAlignment="Top" HorizontalAlignment="Right">
                <Button Width="40" Height="30" Style="{StaticResource PathButtonStyle}" Foreground="White" Tag="M0 0,10 0" />
                <Button Width="40" Height="30" Style="{StaticResource PathButtonStyle}" Foreground="White" Tag="M0 0,0 10,12 10,12 0Z" />
                <Button Width="50" Height="30" Style="{StaticResource PathButtonStyle}" Foreground="White" Tag="M0 0,12 12M0 12,12 0" />
            </StackPanel>
        </Grid>

        <ContentControl x:Name="Main" prism:RegionManager.RegionName="ContentRegion"  Grid.Row="1"/>

    </Grid>
</Grid>

7.后台C#代码

csharp 复制代码

private readonly IRegionManager _regionManager;
 public MainWindowViewModel(IRegionManager regionManager)
 {
     _regionManager = regionManager;
     ShowRegionCommand = new DelegateCommand<object>(ShowRegion);
     InitMenus();
 }

 private void ShowRegion(object o)
 {
     var text = (o as TextBlock).Text;
     _regionManager.RequestNavigate("ContentRegion", text);
 }

 private ObservableCollection<MenuModel> _menuList;
  public ObservableCollection<MenuModel> MenuList
  {
      get { return _menuList; }
      set
      {
          SetProperty(ref _menuList, value);
      }
  }
private void InitMenus()
{
    MenuList = new ObservableCollection<MenuModel>();
    MenuList.Add(new MenuModel()
    {
        Name = "主页",
        Icon = PackIconKind.Home,
        RegionName = "ContentView"
    });
    MenuList.Add(new MenuModel()
    {
        Name = "测试",
        Icon = PackIconKind.CovidTest,
        RegionName = "TestView"
    });
    MenuList.Add(new MenuModel()
    {
        Name = "设置",
        Icon = PackIconKind.Settings,
        RegionName = "SettingView"
    });
}

RegionName 对应每一个创建Control，具体的规则可以看一下prism的导航。

8.MenuModel类

csharp 复制代码

public class MenuModel
{
    public string Name { get; set; }
    public PackIconKind Icon { get; set; }

    public string RegionName { get; set; }
}

9.prism 导航注册

prism 有个注册类ModuleModule

csharp 复制代码

public class ModuleModule : IModule
{
    private readonly IRegionManager _regionManager;

    public ModuleModule(IRegionManager regionManager)
    {
        _regionManager = regionManager;
    }
    /// <summary>
    /// 通知模块已被初始化。
    /// </summary>
    /// <param name="containerProvider"></param>
    public void OnInitialized(IContainerProvider containerProvider)
    {
        _regionManager.RequestNavigate(RegionNames.ContentRegion, "ContentView");
        _regionManager.RequestNavigate(RegionNames.TestRegion, "TestView");
        _regionManager.RequestNavigate(RegionNames.SettingRegion, "SettingView");
    }
    /// <summary>
    /// 用于在您的应用程序将使用的容器中注册类型。
    /// </summary>
    /// <param name="containerRegistry"></param>
    public void RegisterTypes(IContainerRegistry containerRegistry)
    {
        containerRegistry.RegisterForNavigation<ContentView>();
        containerRegistry.RegisterForNavigation<TestView>();
        containerRegistry.RegisterForNavigation<SettingView>();
    }
}

然后在App.xaml.cs中注册

csharp 复制代码

 protected override void ConfigureModuleCatalog(IModuleCatalog moduleCatalog)
 {
     moduleCatalog.AddModule<ModuleModule>();
 }

10.RegionNames类

csharp 复制代码

public static class RegionNames
{
    public const string TestRegion = "TestRegion";
    public const string SettingRegion = "SettingRegion";
    public const string ContentRegion = "ContentRegion";
}

ContentView 、TestView、SettingView是新建的用户控件，自己随便新建可以区分不同控件查看效果即可。
