Tạo ControlBar

Tạo UserControl

Tạo 1 folder chứa UserControl, trong folder đó tạo 1 file UserControl tên là ControlBarUC.xaml

ControlBarUC.xaml

<UserControl x:Class="PCAutoControlOtherApp.DucUserControl.ControlBarUC"
             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:PCAutoControlOtherApp.DucUserControl"
             xmlns:materialDesign="http://materialdesigninxaml.net/winfx/xaml/themes"
             xmlns:i="http://schemas.microsoft.com/expression/2010/interactivity"
             mc:Ignorable="d" 
             x:Name="ucControlBar"
             >
    <i:Interaction.Triggers>
        <i:EventTrigger EventName="MouseLeftButtonDown">
            <i:InvokeCommandAction Command="{Binding MouseLeftButtonDownCommand}" CommandParameter="{Binding ElementName=ucControlBar}"/>
        </i:EventTrigger>
    </i:Interaction.Triggers>
    <Grid>

                        ToolTip="Thu nhỏ" ToolBar.OverflowMode="AsNeeded" Background="ForestGreen">
                        <materialDesign:PackIcon Kind="WindowMinimize" />
                    </Button>
                    <Button Command="{Binding MaximizeWindowCommand}" 
                            CommandParameter="{Binding ElementName=ucControlBar}"
                        ToolTip="Phóng to" ToolBar.OverflowMode="AsNeeded" Background="ForestGreen">

                    </Button>
                </StackPanel>

                <StackPanel DockPanel.Dock="Left" Orientation="Horizontal">
                    <ToggleButton Style="{DynamicResource MaterialDesignHamburgerToggleButton}" />
                    <TextBlock VerticalAlignment="Center" Margin="16 0 0 0" Text="{Binding Tag, ElementName=ucControlBar}"></TextBlock>
                </StackPanel>
            </DockPanel>
        </materialDesign:ColorZone>
    </Grid>
</UserControl>

Sử dụng ControlBar vừa tạo

Tạo 1 project hoặc folder View Model, trong ViewModel, tạo 1 class ControlBarViewModel

Class ControlBarViewModel.cs:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Input;

namespace ViewModel
{
    public class ControlBarViewModel
    {
        public ControlBarViewModel()
        {
            CloseWindowCommand = new RelayCommand<UserControl>((p) => { return p == null ? false : true; }, (p) =>
            {
                FrameworkElement window = GetWindowParent(p);
                var w=window as Window;
                if (w != null) 
                {
                    w.Close();
                }
            });
            MaximizeWindowCommand = new RelayCommand<UserControl>((p) => { return p == null ? false : true; }, (p) =>
            {
                FrameworkElement window = GetWindowParent(p);
                var w = window as Window;
                if (w != null)
                {
                    if(w.WindowState!=WindowState.Maximized)
                    {
                        w.WindowState = WindowState.Maximized;
                    }
                    else
                    {
                        w.WindowState=WindowState.Normal;
                    }
                }
            });
            MinimizeWindowCommand = new RelayCommand<UserControl>((p) => { return p == null ? false : true; }, (p) =>
            {
                FrameworkElement window = GetWindowParent(p);
                var w = window as Window;
                if (w != null)
                {
                    if (w.WindowState != WindowState.Minimized)
                    {
                        w.WindowState = WindowState.Minimized;
                    }
                    else
                    {
                        w.WindowState = WindowState.Maximized;
                    }
                }
            });
            MouseLeftButtonDownCommand = new RelayCommand<UserControl>((p) => { return p == null ? false : true; }, (p) =>
            {
                FrameworkElement window = GetWindowParent(p);
                var w = window as Window;
                if (w != null)
                {
                    w.DragMove();
                }
            });
        }
        public ICommand CloseWindowCommand { get; set; }
        public ICommand MaximizeWindowCommand { get; set; }
        public ICommand MinimizeWindowCommand { get;set; }
        public ICommand MouseLeftButtonDownCommand { get; set; }
        FrameworkElement GetWindowParent(UserControl p)
        {
            FrameworkElement parent = p;
            while(parent.Parent != null)
            {
                parent = parent.Parent as FrameworkElement;
            }
            return parent;
        }
    }
}

Dưới code behind của ControlBarUC.xaml

class ControlBarUC.xaml.cs:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
using ViewModel;
namespace PCAutoControlOtherApp.DucUserControl
{
    /// <summary>
    /// Interaction logic for ControlBarUC.xaml
    /// </summary>
    public partial class ControlBarUC : UserControl
    {
        public ControlBarViewModel ViewModel { get; set; }
        public ControlBarUC()
        {
            InitializeComponent();
            this.DataContext = ViewModel = new ControlBarViewModel();
        }
    }
}

Quay lại MainWindow.xaml, thêm code này vào để tạo 1 biến tham chiếu đến UserControl

xmlns:UserControl="clr-namespace:PCAutoControlOtherApp.DucUserControl"

Sửa tiêu đề ControlBar

Thêm code này vào MainWindow.xaml

<UserControl:ControlBarUC Tag="{Binding Title, ElementName= <!--Name của window--!>}"></UserControl:ControlBarUC>

Tóm code lại

MainWindow.xaml
