创建侧边栏实体类

新建MenuBar文件

Common
- Models
  - MenuBar

WPF MaterialDesign 初学项目实战（3）动态侧边栏

添加基本成员

using MaterialDesignColors.Recommended;
using Prism.Mvvm;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace MyToDo.Common.Models
{
    /// <summary>
    /// 系统导航菜单
    /// </summary>
    public class MenuBar : BindableBase//继承BindableBase可以动态修改
    {
        /// <summary>
        /// 菜单图标
        /// </summary>
        public string? Icon { get; set; }

        /// <summary>
        /// 标题
        /// </summary>
        public string? Title { get; set; }   

        /// <summary>
        /// 命名空间
        /// </summary>
        public string? NameSpace { get; set; }

    }
}

创建Views和ViewModels文件夹

注意,Views和VIewModels文件夹的名字是一定要这么写，这和Prism框架的自动绑定有关
绑定关系为：

Views
- xxxView
ViewModels
- xxxViewModel

自动绑定命名空间为：

xmlns:prism="http://prismlibrary.com/"
prism:ViewModelLocator.AutoWireViewModel="True"

创建MainView和MainViewModel文件

将MainWindow内容复制到MainView里面，将命名空间进行修改

MainViewModel文件，添加View文件上下文

using MyToDo.Common.Models;
using Prism.Mvvm;
using System;
using System.Collections.Generic;
using System.Collections.ObjectModel;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace MyToDo.ViewModels
{
    public class MainViewModel : BindableBase//继承BindableBase可以动态更新
    {
        public MainViewModel()
        {
            MenuBars = new ObservableCollection<MenuBar>();
            CreateMenuBar();
        }

        private ObservableCollection<MenuBar> menuBars;

        public ObservableCollection<MenuBar> MenuBars
        {
            get { return menuBars; }
            set { menuBars= value; RaisePropertyChanged(); }
        } //动态更新列表

        void CreateMenuBar()
        {
            MenuBars.Add(new MenuBar { Icon = "Home", Title = "首页", NameSpace = "IndexView" });
            MenuBars.Add(new MenuBar { Icon = "Notebook", Title = "代办事项", NameSpace = "ToDoView" });
            MenuBars.Add(new MenuBar { Icon = "NotebookEdit", Title = "备忘录", NameSpace = "MemoView" });
            MenuBars.Add(new MenuBar { Icon = "CogOutline", Title = "设置", NameSpace = "SettingView" });
        }
    }
}

PS:为什么要有private menuBars 和 public MenuBars
WPF MaterialDesign 初学项目实战（3）动态侧边栏

        public ObservableCollection<MenuBar> MenuBars
        {
            get { return MenuBars; }//这里会报错
            set { MenuBars = value; RaisePropertyChanged(); }
        } //动态更新列表


        private ObservableCollection<MenuBar> menuBars;
        public ObservableCollection<MenuBar> MenuBars
        {
            get { return menuBars; }
            set { menuBars= value; RaisePropertyChanged(); }
        } //动态更新列表

删除原来的MainWindow文件

在App.xmal里面修改启动窗口

 public partial class App : PrismApplication
    {
        /// <summary>
        /// 重写运行主窗口
        /// </summary>
        /// <returns></returns>
        /// <exception cref="NotImplementedException"></exception>
        protected override Window CreateShell()
        {
            //重定向主窗口
            - return Container.Resolve<MainWindow>();
            + return Container.Resolve<MainView>();
            
        }

        /// <summary>
        /// 依赖注入
        /// </summary>
        /// <param name="containerRegistry"></param>
        protected override void RegisterTypes(IContainerRegistry containerRegistry)
        {
           
        }
    }

将元素添加到MainView页面
绑定数据上下文：{Binding 属性名}

注意：Views文件夹和ViewModels文件夹必须这样命名，启用Prism的自动联系上下文功能，并且对应文件名为MainView和MainViewModels

WPF MaterialDesign 初学项目实战（3）动态侧边栏

prism启动上下文功能：

xmlns:prism="http://prismlibrary.com/"
prism:ViewModelLocator.AutoWireViewModel="True"

<materialDesign:DrawerHost IsLeftDrawerOpen="{Binding ElementName=MenuToggleButton, Path=IsChecked}">
            <materialDesign:DrawerHost.LeftDrawerContent>
                <DockPanel MinWidth="220">
                    <StackPanel>
                        <Image Width="50"
                               Height="50"
                               Source="/static/img/User/icon.png">
                            <Image.Clip>
                                <EllipseGeometry Center="25,25"
                                                 RadiusX="25"
                                                 RadiusY="25" />
                            </Image.Clip>
                        </Image>
                        <TextBlock  Text="Gclove2000"
                                    HorizontalAlignment="Center"
                                    />

                        <ListBox ItemsSource="{Binding MenuBars}" >
                            <ListBox.ItemTemplate>
                                <DataTemplate>
                                    <StackPanel Orientation="Horizontal">
                                        <materialDesign:PackIcon Kind="{Binding Icon}" />
                                        <TextBlock Text="{Binding Title}" Margin="10,0"/>
                                    </StackPanel>
                                </DataTemplate>
                            </ListBox.ItemTemplate>
                        </ListBox>
                    </StackPanel>
                </DockPanel>
            </materialDesign:DrawerHost.LeftDrawerContent>

                                            TargetName="borderHeader"
                                            Value="{DynamicResource PrimaryHueLightBrush}" />
                                </Trigger>
                            </ControlTemplate.Triggers>
                        </ControlTemplate>
                    </Setter.Value>
                </Setter>
            </Style>
        </ResourceDictionary>
    </Application.Resources>
</prism:PrismApplication>

在对应元素中引用样式

<ListBox ItemsSource="{Binding MenuBars}" 
+ ItemContainerStyle="{StaticResource MyListBoxItemStyle}" >
                            <ListBox.ItemTemplate>
                                <DataTemplate>
                                    <StackPanel Orientation="Horizontal">
                                        <materialDesign:PackIcon Kind="{Binding Icon}" Margin="15,0" />
                                        <TextBlock Text="{Binding Title}" Margin="10,0"/>
                                    </StackPanel>
                                </DataTemplate>
                            </ListBox.ItemTemplate>
                        </ListBox>

实现效果：有点丑，可以后面改一下
WPF MaterialDesign 初学项目实战（3）动态侧边栏

设置点击范围

WPF MaterialDesign 初学项目实战（3）动态侧边栏

<StackPanel Orientation="Horizontal"
            VerticalAlignment="Center"
            + Background="Transparent">没设置为蓝色点击范围，设置了为红色点击范围
    <materialDesign:PackIcon Kind="{Binding Icon}"
                             Margin="15,0" />
    <TextBlock Text="{Binding Title}"
               Margin="10,0" />
</StackPanel>

设置鼠标悬停效果
