前言

有小夥伴提出需要實現Win10漢堡菜單效果。

由於在WPF中沒有現成的類似UWP的漢堡菜單，所以我們自己實現一個。

一、創建 Win10Menu.cs 菜單繼承 ContentControl 代碼如下。

　　1、IsOpen ：判定是否展開、收起。

　　2、Content ：存放菜單集合。

　　3、SelectionIndicatorColor ：選中菜單狀態欄顏色。

　　4、MenuItemForeground：菜單集字體顏色。

using System.Collections.Generic;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Media;

namespace WPFDevelopers.Controls
{
    public class Win10Menu : ContentControl
    {
        public new List<Win10MenuItem> Content
        {
            get { return (List<Win10MenuItem>)GetValue(ContentProperty); }
            set { SetValue(ContentProperty, value); }
        }

        public new static readonly DependencyProperty ContentProperty =
            DependencyProperty.Register("Content", typeof(List<Win10MenuItem>), typeof(Win10Menu),new FrameworkPropertyMetadata(null));

        static Win10Menu()
        {
            DefaultStyleKeyProperty.OverrideMetadata(typeof(Win10Menu), new FrameworkPropertyMetadata(typeof(Win10Menu)));
        }

        public override void BeginInit()
        {
            Content = new List<Win10MenuItem>();
            base.BeginInit();
        }

        public bool IsOpen
        {
            get { return (bool)GetValue(IsOpenProperty); }
            set
            {
                SetValue(IsOpenProperty, value);
            }
        }

        public static readonly DependencyProperty IsOpenProperty =
            DependencyProperty.Register("IsOpen", typeof(bool), typeof(Win10Menu), new PropertyMetadata(true));


        public System.Windows.Media.Brush MenuIconColor
        {
            get { return (System.Windows.Media.Brush)GetValue(MenuIconColorProperty); }
            set { SetValue(MenuIconColorProperty, value); }
        }

        public static readonly DependencyProperty MenuIconColorProperty =
            DependencyProperty.Register("MenuIconColor", typeof(System.Windows.Media.Brush), typeof(Win10Menu), new PropertyMetadata(Brushes.White));


        public Brush SelectionIndicatorColor
        {
            get { return (Brush)GetValue(SelectionIndicatorColorProperty); }
            set { SetValue(SelectionIndicatorColorProperty, value); }
        }

        public static readonly DependencyProperty SelectionIndicatorColorProperty =
            DependencyProperty.Register("SelectionIndicatorColor", typeof(Brush), typeof(Win10Menu), new PropertyMetadata(Brushes.Red));

        public Brush MenuItemForeground
        {
            get { return (Brush)GetValue(MenuItemForegroundProperty); }
            set { SetValue(MenuItemForegroundProperty, value); }
        }

        public static readonly DependencyProperty MenuItemForegroundProperty =
            DependencyProperty.Register("MenuItemForeground", typeof(Brush), typeof(Win10Menu), new PropertyMetadata(Brushes.Transparent));
    }
}

二、創建 Win10Menu.xaml 爲 Win10Menu.cs 進行佈局代碼如下

Win10Menu.xaml 思路如下

1、ToggleButton ：控制IsChecked動畫如下

IsOpen = False：DoubleAnimation修改controls:Win10Menu的Width爲 180。

IsOpen = True ：DoubleAnimation修改controls:Win10Menu的Width爲 50。

2、ListBox：ItemsSource="{TemplateBinding Content}"展示菜單集合。

需注意如下

ScrollViewer.HorizontalScrollBarVisibility="Disabled"，不然當Win10Menu的Width 爲50時會出現滾動條。

<Style TargetType="ToggleButton">
        <Setter Property="IsChecked" Value="False"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type ToggleButton}">
                    <Grid Background="{TemplateBinding Background}">
                        <ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center" />
                    </Grid>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
        <Style.Triggers>
            <Trigger Property="IsMouseOver" Value="True">
                <Setter Property="Opacity" Value="0.8" />
                <Setter Property="Cursor" Value="Hand" />
                <Setter Property="Template">

                            <Border
                                        Background="{TemplateBinding Background}"
                                        BorderBrush="Black"
                                        BorderThickness="1">
                                <ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center" />
                            </Border>
                        </ControlTemplate>
                    </Setter.Value>
                </Setter>
            </Trigger>
        </Style.Triggers>
</Style>
    <Style TargetType="ListBox">
        <Setter Property="Background" Value="Transparent" />
        <Setter Property="BorderBrush" Value="Transparent" />
        <Setter Property="Template">

        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="controls:Win10Menu">
                    <Grid Background="{TemplateBinding Background}">
                        <ToggleButton HorizontalAlignment="Left" Background="#333"
                                      VerticalAlignment="Top" Height="40" Width="50"
                                      IsChecked="{Binding RelativeSource={RelativeSource AncestorType={x:Type controls:Win10Menu}}, Path=IsOpen}">
                            <Path HorizontalAlignment="Center" 
                                  VerticalAlignment="Center"

                                  Fill="{TemplateBinding MenuIconColor}"
                                  Data="{StaticResource PathMenu}"/>
                        </ToggleButton>
                        <ListBox ItemsSource="{TemplateBinding Content}"

                    </Grid>

        </Setter>
        <Style.Triggers>
            <Trigger Property="IsOpen" Value="False">
                <Trigger.EnterActions>
                    <BeginStoryboard>
                        <Storyboard>
                            <DoubleAnimation 
                                         Storyboard.TargetProperty="Width"
                                         To="180"
                                         Duration="0:0:0.2"/>
                        </Storyboard>

                        <Storyboard>
                            <DoubleAnimation 
                                         Storyboard.TargetProperty="Width"
                                         To="50"
                                         Duration="0:0:0.2"/>
                        </Storyboard>
                    </BeginStoryboard>
                </Trigger.ExitActions>
            </Trigger>
        </Style.Triggers>
</Style>

三、創建 Win10MenuItem.cs 繼承 ListBoxItem 代碼如下。

Win10MenuItem.cs 思路如下

1、Text 菜單文本內容展示。

2、Icon 菜單圖標爲ImageSource類型。

3、SelectionIndicatorColor選中的側邊狀態顏色。

4、SelectionCommand 選中事件。

using System.Windows;
using System.Windows.Controls;
using System.Windows.Input;
using System.Windows.Media;

namespace WPFDevelopers.Controls
{
    public class Win10MenuItem : ListBoxItem
    {
        static Win10MenuItem()
        {
            DefaultStyleKeyProperty.OverrideMetadata(typeof(Win10MenuItem), new FrameworkPropertyMetadata(typeof(Win10MenuItem)));
        }
        public string Text
        {
            get { return (string)GetValue(TextProperty); }
            set { SetValue(TextProperty, value); }
        }

        public static readonly DependencyProperty TextProperty =
            DependencyProperty.Register("Text", typeof(string), typeof(Win10MenuItem), new PropertyMetadata(string.Empty));


        public ImageSource Icon
        {
            get { return (ImageSource)GetValue(IconProperty); }
            set { SetValue(IconProperty, value); }
        }

        public static readonly DependencyProperty IconProperty =
            DependencyProperty.Register("Icon", typeof(ImageSource), typeof(Win10MenuItem), new PropertyMetadata(null));

        public Brush SelectionIndicatorColor
        {
            get { return (Brush)GetValue(SelectionIndicatorColorProperty); }
            set { SetValue(SelectionIndicatorColorProperty, value); }
        }

        public static readonly DependencyProperty SelectionIndicatorColorProperty =
            DependencyProperty.Register("SelectionIndicatorColor", typeof(Brush), typeof(Win10MenuItem), new PropertyMetadata(Brushes.Blue));

        public ICommand SelectionCommand
        {
            get { return (ICommand)GetValue(SelectionCommandProperty); }
            set { SetValue(SelectionCommandProperty, value); }
        }

        public static readonly DependencyProperty SelectionCommandProperty =
            DependencyProperty.Register("SelectionCommand", typeof(ICommand), typeof(Win10MenuItem), new PropertyMetadata(null));
    }
}

四、創建 Win10MenuItem.xaml 爲 Win10MenuItem.cs 進行佈局代碼如下

<Style x:Key="ButtonFocusVisual">
        <Setter Property="Control.Template">
            <Setter.Value>
                <ControlTemplate>
                    <Border>
                        <Rectangle 
            Margin="2"
            StrokeThickness="1"
            Stroke="#60000000"
            StrokeDashArray="1 2"/>
                    </Border>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
</Style>

    <!-- Fill Brushes -->

    <SolidColorBrush x:Key="NormalBrush" Color="Transparent" />
    <SolidColorBrush x:Key="DarkBrush" Color="#ddd" />
    <SolidColorBrush x:Key="PressedBrush" Color="#80FFFFFF" />
    <SolidColorBrush x:Key="DisabledForegroundBrush" Color="Transparent" />
    <SolidColorBrush x:Key="DisabledBackgroundBrush" Color="Transparent" />

    <!-- Border Brushes -->

    <SolidColorBrush x:Key="NormalBorderBrush" Color="Transparent" />
    <SolidColorBrush x:Key="PressedBorderBrush" Color="Transparent" />
    <SolidColorBrush x:Key="DefaultedBorderBrush" Color="Transparent" />
    <SolidColorBrush x:Key="DisabledBorderBrush" Color="Transparent" />


    <Style TargetType="Button">
        <Setter Property="SnapsToDevicePixels" Value="true"/>

        <Setter Property="MinHeight" Value="23"/>
        <Setter Property="MinWidth" Value="75"/>
        <Setter Property="Cursor" Value="Hand" />
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="Button">
                    <Border 
          x:Name="Border"

            HorizontalAlignment="Stretch"
            VerticalAlignment="Stretch"
            RecognizesAccessKey="True"/>
                    </Border>
                    <ControlTemplate.Triggers>
                        <Trigger Property="IsKeyboardFocused" Value="true">

                            <Trigger.ExitActions>
                                <BeginStoryboard>
                                    <Storyboard>
                                        <BooleanAnimationUsingKeyFrames Storyboard.TargetProperty="IsSelected">
                                            <DiscreteBooleanKeyFrame KeyTime="00:00:00" Value="True" />
                                        </BooleanAnimationUsingKeyFrames>
                                    </Storyboard>
                                </BeginStoryboard>
                            </Trigger.ExitActions>
                        </Trigger>
                    </ControlTemplate.Triggers>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
</Style>

五、創建Win10MenuExample.xaml代碼如下

Win10MenuExample.xaml實現思路如下

1、Grid佈局分爲兩列設置第零列Width爲Auto自適應。

2、第零列爲Win10menu。

3、第一列爲Frame設置NavigationUIVisibility="Hidden"

<UserControl x:Class="WPFDevelopers.Samples.ExampleViews.Win10Menu.Win10MenuExample"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
             xmlns:local="clr-namespace:WPFDevelopers.Samples.ExampleViews.Win10Menu"
             xmlns:wpfdev="https://github.com/yanjinhuagood/WPFDevelopers"
             mc:Ignorable="d" 
             d:DesignHeight="450" d:DesignWidth="800">
    <Grid Background="#FF7B7BFF">
        <Grid.ColumnDefinitions>
            <ColumnDefinition  Width="Auto"/>
            <ColumnDefinition/>
        </Grid.ColumnDefinitions>
        <wpfdev:Win10Menu Background="#eee"
                          SelectionIndicatorColor="{StaticResource PrimaryPressedSolidColorBrush}" 
                          MenuItemForeground="{StaticResource BlackSolidColorBrush}" HorizontalAlignment="Left">
            <wpfdev:Win10Menu.Content>
                <wpfdev:Win10MenuItem Icon="pack://application:,,,/Images/CircularMenu/2.png" Text="主頁"
                                      SelectionCommand="{Binding HomeCommand,RelativeSource={RelativeSource AncestorType=local:Win10MenuExample}}"/>
                <wpfdev:Win10MenuItem Icon="pack://application:,,,/Images/CircularMenu/4.png" Text="Edge"
                                      SelectionCommand="{Binding EdgeCommand,RelativeSource={RelativeSource AncestorType=local:Win10MenuExample}}"/>
                <wpfdev:Win10MenuItem Icon="pack://application:,,,/Images/CircularMenu/1.png" Text="雲盤"
                                      SelectionCommand="{Binding CloudCommand,RelativeSource={RelativeSource AncestorType=local:Win10MenuExample}}"/>
                <wpfdev:Win10MenuItem Icon="pack://application:,,,/Images/CircularMenu/8.png" Text="郵件"
                                      SelectionCommand="{Binding MailCommand,RelativeSource={RelativeSource AncestorType=local:Win10MenuExample}}"/>
                <wpfdev:Win10MenuItem Icon="pack://application:,,,/Images/CircularMenu/6.png" Text="視頻"
                                      SelectionCommand="{Binding VideoCommand,RelativeSource={RelativeSource AncestorType=local:Win10MenuExample}}"/>
            </wpfdev:Win10Menu.Content>
        </wpfdev:Win10Menu>
        <Frame Name="myFrame" Grid.Column="1" Margin="0,40,0,0"
               NavigationUIVisibility="Hidden"></Frame>
    </Grid>
</UserControl>

六、創建Win10MenuExample.xaml.cs代碼如下

Win10MenuExample.xaml實現思路如下

1、定義List<Uri>賦值集合爲菜單需要跳轉的頁面。

2、構造爲myFrame.Navigate(_uriList[0]);第零頁。

using System;
using System.Collections.Generic;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Input;
using WPFDevelopers.Samples.Helpers;

namespace WPFDevelopers.Samples.ExampleViews.Win10Menu
{
    /// <summary>
    /// Win10MenuExample.xaml 的交互邏輯
    /// </summary>
    public partial class Win10MenuExample : UserControl
    {
        private List<Uri> _uriList = new List<Uri>()
        {
            new Uri("ExampleViews/Win10Menu/HomePage.xaml",UriKind.Relative),
            new Uri("ExampleViews/Win10Menu/EdgePage.xaml",UriKind.Relative),
        };
        public Win10MenuExample()
        {
            InitializeComponent();
            myFrame.Navigate(_uriList[0]);
        }

        public ICommand HomeCommand => new RelayCommand(obj =>
        {
            myFrame.Navigate(_uriList[0]);
        });
        public ICommand EdgeCommand => new RelayCommand(obj =>
        {
            myFrame.Navigate(_uriList[1]);
        });
        public ICommand CloudCommand => new RelayCommand(obj =>
        {
            MessageBox.Show("點擊了雲盤");
        });
        public ICommand MailCommand => new RelayCommand(obj =>
        {
            MessageBox.Show("點擊了郵件");
        });
        public ICommand VideoCommand => new RelayCommand(obj =>
        {
            MessageBox.Show("點擊了視頻");
        });
    }
}
