WPF实战学习笔记24-首页编辑与完成
首页编辑与完成
- indexview添加Listbox控件的鼠标双击行为
- 添加todo、memo的编辑命令
- indexviewmodel添加对应的更新事件处理
- 添加ToggleButton与后台的绑定
- 将ToggleButton的ischeck绑定到status属性
- 添加bool int 转换器
- 添加完成命令
- 添加完成功能函数
Listbox添加行为
给行为添加命令空间
文件：Mytodo.Views.IndexView.cs
xmlns:i="http://schemas.microsoft.com/xaml/behaviors"
添加行为事件
文件：Mytodo.Views.IndexView.cs
后台添加对应的命令，并初始化
文件：Mytodo.Views.IndexViewmodel.cs
///
/// 命令：编辑备忘
///
public DelegateCommand EditMemoCmd { get;private set; }
///
/// 命令：编辑待办
///
public DelegateCommand EditTodoCmd { get; private set; }
//初始化命令
EditMemoCmd = new DelegateCommand(Addmemo);
EditTodoCmd = new DelegateCommand(Addtodo);
添加命令方法
文件：Mytodo.Views.IndexViewmodel.cs
///
/// 添加待办事项
///
async void Addtodo(ToDoDto model)
{
DialogParameters param = new DialogParameters();
if (model != null)
param.Add("Value", model);
var dialogres = await dialog.ShowDialog("AddTodoView", param);
var newtodo = dialogres.Parameters.GetValue("Value");
if (newtodo == null || string.IsNullOrEmpty(newtodo.Title) || (string.IsNullOrEmpty(newtodo.Content)))
return;
if (dialogres.Result == ButtonResult.OK)
{
try
{
if (newtodo.Id > 0)
{
var updres = await toDoService.UpdateAsync(newtodo);
if (updres.Status)
{
var todo = TodoDtos.FirstOrDefault(x=>x.Id.Equals(newtodo.Id));
//更新信息
todo.Content = newtodo.Content;
todo.Title = newtodo.Title;
todo.Status = newtodo.Status;
}
}
else
{
//添加内容
//更新数据库数据
var addres = await toDoService.AddAsync(newtodo);
//更新UI数据
if (addres.Status)
{
TodoDtos.Add(addres.Result);
}
}
}
catch
{
}
finally
{
UpdateLoding(false);
}
}
}
///
/// 添加备忘录
///
async void Addmemo(MemoDto model)
{
DialogParameters param = new DialogParameters();
if (model != null)
param.Add("Value", model);
var dialogres = await dialog.ShowDialog("AddMemoView", param);
if (dialogres.Result == ButtonResult.OK)
{
try
{
var newmemo = dialogres.Parameters.GetValue("Value");
if (newmemo != null && string.IsNullOrWhiteSpace(newmemo.Content) && string.IsNullOrWhiteSpace(newmemo.Title))
return;
if (newmemo.Id > 0)
{
var updres = await memoService.UpdateAsync(newmemo);
if (updres.Status)
{
//var memo = MemoDtos.FindFirst(predicate: x => x.Id == newmemo.Id);
var memo = MemoDtos.FirstOrDefault( x => x.Id.Equals( newmemo.Id));
//更新信息
memo.Content = newmemo.Content;
memo.Title = newmemo.Title;
}
}
else
{
//添加内容
var addres = await memoService.AddAsync(newmemo);
//更新UI数据
if (addres.Status)
{
MemoDtos.Add(addres.Result);
}
}
}
catch
{
}
finally
{
UpdateLoding(false);
}
}
}
添加ToggleButton绑定与check事件
添加转换器
添加文件:Mytodo.Common.Converters.BoolInt_TConverter.cs
using System;
using System.Collections.Generic;
using System.Globalization;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Data;
namespace Mytodo.Common.Converters
{
public class BoolInt_TConverter : IValueConverter
{
///
/// int to bool
///
///
///
///
///
///
/// bool to int
///
///
///
///
///
/// 添加转换器，添加命令
修改文件：Mytodo.Views.IndexView.xaml
- 添加命名空间
xmlns:cv="clr-namespace:Mytodo.Common.Converters"
-
添加资源
-
绑定命令，添加转换器
-
定义命令，并初始化
////// Todo完成命令 /// public DelegateCommandToDoCompltedCommand { get; set; } public IndexViewModel(IContainerProvider provider, IDialogHostService dialog) : base(provider) { //实例化接口 this.toDoService= provider.Resolve (); this.memoService = provider.Resolve (); //实例化对象 MemoDtos = new ObservableCollection (); TodoDtos = new ObservableCollection (); //初始化命令 EditMemoCmd = new DelegateCommand (Addmemo); EditTodoCmd = new DelegateCommand (Addtodo); ToDoCompltedCommand = new DelegateCommand (Compete); ExecuteCommand = new DelegateCommand (Execute); this.dialog = dialog; CreatBars(); } -
初始化命令操作函数
////// togglebutoon 的命令 /// /// ///async private void Compete(ToDoDto dto) { if (dto == null || string.IsNullOrEmpty(dto.Title) || (string.IsNullOrEmpty(dto.Content))) return; var updres = await toDoService.UpdateAsync(dto); if (updres.Status) { var todo = TodoDtos.FirstOrDefault(x => x.Id.Equals(dto.Id)); //更新信息 todo.Status = dto.Status; } }
