WPF实战项目二十二（客户端）：首页添加备忘录与待办事项

1、在View文件夹下新建文件夹Dialog，新建View：AddMemoView、AddToDoView

    
        
            
            
            
        
        
        
            
                
                
                    待办
                    已完成
                
            

            
            
            
            
            
        

        
            
            
        
    

 2、IndexView中修改按钮，绑定方法：ExecuteCommand

 3、ViewModels新建Dialogs文件夹，新建AddMemoViewModel、AddToDoViewModel

public class AddMemoViewModel : IDialogAware
    {
        public string Title {get;set;}

        public event Action RequestClose;

        public bool CanCloseDialog()
        {
            return true;
        }

        public void OnDialogClosed()
        {
            
        }

        public void OnDialogOpened(IDialogParameters parameters)
        {
            
        }
    }

public class AddToDoViewModel : IDialogAware
    {
        public string Title {get; set;}

        public event Action RequestClose;

        public bool CanCloseDialog()
        {
            return true;
        }

        public void OnDialogClosed()
        {
            
        }

        public void OnDialogOpened(IDialogParameters parameters)
        {
            
        }
    }

4、修改IndexViewModel

using Prism.Commands;
using Prism.Mvvm;
using Prism.Services.Dialogs;
using System.Collections.ObjectModel;
using WPFProject.Common.Models;
using WPFProjectShared.Dtos;

namespace WPFProject.ViewModels
{
    public class IndexViewModel : BindableBase
    {
        public IndexViewModel(IDialogService dialog)
        {
            TaskBars = new ObservableCollection();
            CreateTaskBars();
            ToDoDtos = new ObservableCollection();
            MemoDtos = new ObservableCollection();
            ExecuteCommand = new DelegateCommand(Execute);
            this.dialog = dialog;
        }

        private void Execute(string obj)
        {
            switch (obj)
            {
                case "新增待办事项":AddToDo();break;
                case "新增备忘录":AddMemo();break;
            }
        }

        private void AddMemo()
        {
            dialog.ShowDialog("AddToDoView");
        }

        private void AddToDo()
        {
            dialog.ShowDialog("AddMemoView");
        }

        public DelegateCommand ExecuteCommand { get; private set; }

        #region 属性
        /// 

        /// 列表
        /// 
        private ObservableCollection taskBars;

        public ObservableCollection TaskBars
        {
            get { return taskBars; }
            set { taskBars = value; RaisePropertyChanged(); }
        }
        /// 

        /// 代办事项
        /// 
        private ObservableCollection toDoDtos;

        public ObservableCollection ToDoDtos
        {
            get { return toDoDtos; }
            set { toDoDtos = value; RaisePropertyChanged(); }
        }

        /// 

        /// 备忘录
        /// 
        private ObservableCollection memoDtos;
        private readonly IDialogService dialog;

        public ObservableCollection MemoDtos
        {
            get { return memoDtos; }
            set { memoDtos = value; RaisePropertyChanged(); }
        }
        #endregion


        private void CreateTaskBars()
        {
            TaskBars.Add(new TaskBar() { Icon = "ClockFast", Title = "汇总", Content = "27", Color = "#0CA0FF", Target = "" });
            TaskBars.Add(new TaskBar() { Icon = "ClockCheckOutLine", Title = "已完成", Content = "24", Color = "#1ECA3A", Target = "" });
            TaskBars.Add(new TaskBar() { Icon = "ChartLineVariant", Title = "完成比例", Content = "89%", Color = "#02C6DC", Target = "" });
            TaskBars.Add(new TaskBar() { Icon = "PlaylistStar", Title = "备忘录", Content = "13", Color = "#FFA000", Target = "" });
        }


        
    }
}

 5、在App.xmal.cs中注册弹窗

//注册弹窗
            containerRegistry.RegisterDialog();
            containerRegistry.RegisterDialog();

6、F5运行项目
