可分组的选择框控件(MVVM下)(Toggle样式 仿造单选框RadioButton，复选框CheckBox功能)
原地址： http://www.cnblogs.com/yk250/p/5660340.html
效果图如下：支持分组的单选框，复选框样式和MVVM下功能的实现。这是项目中一个快捷键功能的扩展。
1，准备工作：VS2015 (15对WPF的支持变得异常的好，调试模式下允许自动更改属性。)，随VS发布的Blend，几个基础类：
1 public class RelayCommand : ICommand 2 { 3 #region Fields 4 5 readonly Action<object> _executeAct; 6 readonly Predicate<object> _canExecutePre; 7 private readonly Action _execute; 8 9 private readonly Func<bool> _canExecute; 10 #endregion 11 12 #region Constructors 13 14 /// <summary> 15 /// Creates a new command that can always execute. 16 /// </summary> 17 /// <param name="execute">The execution logic.</param> 18 public RelayCommand(Action<object> execute) 19 : this(execute, null) 20 { 21 } 22 23 /// <summary> 24 /// Creates a new command. 25 /// </summary> 26 /// <param name="execute">The execution logic.</param> 27 /// <param name="canExecute">The execution status logic.</param> 28 public RelayCommand(Action<object> execute, Predicate<object> canExecute) 29 { 30 if (execute == null) 31 { 32 throw new ArgumentNullException("execute"); 33 } 34 35 _executeAct = execute; 36 _canExecutePre = canExecute; 37 } 38 39 40 /// <summary> 41 /// Initializes a new instance of the RelayCommand class that 42 /// can always execute. 43 /// </summary> 44 /// <param name="execute">The execution logic.</param> 45 /// <exception cref="ArgumentNullException">If the execute argument is null.</exception> 46 public RelayCommand(Action execute) 47 : this(execute, null) 48 { 49 } 50 51 /// <summary> 52 /// Initializes a new instance of the RelayCommand class. 53 /// </summary> 54 /// <param name="execute">The execution logic.</param> 55 /// <param name="canExecute">The execution status logic.</param> 56 /// <exception cref="ArgumentNullException">If the execute argument is null.</exception> 57 public RelayCommand(Action execute, Func<bool> canExecute) 58 { 59 if (execute == null) 60 { 61 throw new ArgumentNullException("execute"); 62 } 63 64 _execute = execute; 65 _canExecute = canExecute; 66 } 67 68 #endregion 69 70 #region ICommand Members 71 72 public bool CanExecute(object parameter) 73 { 74 if (parameter == null) 75 { 76 return _canExecute == null ? true : _canExecute(); 77 } 78 79 return _canExecutePre == null ? true : _canExecutePre(parameter); 80 } 81 82 public event EventHandler CanExecuteChanged 83 { 84 add { CommandManager.RequerySuggested += value; } 85 remove { CommandManager.RequerySuggested -= value; } 86 } 87 88 public void Execute(object parameter) 89 { 90 if (!CanExecute(parameter)) 91 return; 92 if (parameter == null) 93 { 94 if (_execute != null) 95 _execute(); 96 return; 97 } 98 if (_executeAct != null) 99 _executeAct(parameter); 100 101 } 102 103 #endregion 104 }
1 public class ModelBase : INotifyPropertyChanged 2 { 3 /// <summary> 4 /// 属性改变事件 5 /// </summary> 6 public event PropertyChangedEventHandler PropertyChanged; 7 8 /// <summary> 9 /// 触发属性改变 10 /// </summary> 11 /// <param name="propertyName"></param> 12 protected virtual void RaisePropertyChangedEvent(string propertyName) 13 { 14 ///一般写法 15 // PropertyChangedEventHandler handler = this.PropertyChanged; 16 // if (handler != null) handler(this, new PropertyChangedEventArgs(propertyName)); 17 ///简易写法 18 PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName)); 19 } 20 }

样式和颜色都是根据自己喜好来的，可以随意修改的。关键点事要用Path画出选中的钩，然后通过数据触发器将选中和不选中的姿态通过动画来展示：
<Trigger Property="IsChecked" Value="true">
<Trigger.EnterActions>
<BeginStoryboard Storyboard="{StaticResource Checked}"></BeginStoryboard>
</Trigger.EnterActions>
<Trigger.ExitActions>
<BeginStoryboard Storyboard="{StaticResource Unchecked}"></BeginStoryboard>
</Trigger.ExitActions>
</Trigger>
3，定义ViewModel和相关结构：
首先是定义选中的3个状态：多行多选，多行单选，以及单行单选。（其它类型请自行添加和实现。）
public enum CheckType
{
MutilChecked,
SingleChecked,
RowChecked
}
然后是 设计层次结构：通用来讲我这里粗略的设计成嵌套类型，即数据源为List<setmodel>类型，而setmodel中又包含ObservableCollection<tgmodel>类型，而这个tgmodel呢，其实就是精确到的每一个按钮对应的模型了。下面给出具体定义：
1 public class setmodel : ModelBase 2 { 3 private string _name; 4 /// <summary> 5 /// 显示名称 6 /// </summary> 7 public string Name 8 { 9 get { return _name; } 10 set 11 { 12 _name = value; 13 RaisePropertyChangedEvent("Name"); 14 } 15 } 16 17 private string _groupname = "singlecheck"; 18 /// <summary> 19 /// 显示名称 20 /// </summary> 21 public string GroupName 22 { 23 get { return _groupname; } 24 set 25 { 26 _groupname = value; 27 RaisePropertyChangedEvent("GroupName"); 28 } 29 } 30 public ObservableCollection<tgmodel> TgLists { get; set; } 31 32 33 }
1 public class tgmodel : ModelBase 2 { 3 public tgmodel() 4 { 5 CommandDefine = new CommandDefine(); 6 } 7 private string content; 8 /// <summary> 9 /// Toggle按钮显示内容 10 /// </summary> 11 public string Content 12 { 13 get { return content; } 14 set 15 { 16 content = value; 17 RaisePropertyChangedEvent("Content"); 18 } 19 } 20 21 22 private bool ischecked; 23 /// <summary> 24 /// 是否选中 25 /// </summary> 26 public bool IsChecked 27 { 28 get { return ischecked; } 29 set 30 { 31 ischecked = value; 32 RaisePropertyChangedEvent("IsChecked"); 33 } 34 } 35 public ICommand CheckedCommand { get; set; } 36 public CommandDefine CommandDefine { get; set; } 37 }
然后这里写了一个队togglebutton 信息的辅助类：主要是封装了togglebutton对应的模型 TgModel,它所在组的 上一级模型 SetModel,所在行的名称 RowName。
public class TgInfo
{
public tgmodel TgModel { get; set; }
public setmodel SetModel { get; set; }
public string RowName { get; set; }
//public CheckType CheckType { get; set; }
//public List<setmodel> SourceLists { get; set; }
}
4，最后就是功能的实现了，这里代码有点乱，还有进一步修改的可能。
（1）初始化DataContext,先是ViewModel:
SettingListsSingle 是我上面单行拿来做选择项的集合，下面的三行数据数据源则是
SettingLists。
1 public class ViewModel : ModelBase 2 { 3 /// <summary> 4 /// 设置列表 5 /// </summary> 6 public List<setmodel> SettingLists { get; set; } 7 public List<setmodel> SettingListsSingle { get; set; } 8 9 private CheckType _checktype; 10 /// <summary> 11 /// 选项类型 12 /// </summary> 13 public CheckType CheckType 14 { 15 get { return _checktype; } 16 set 17 { 18 _checktype = value; 19 RaisePropertyChangedEvent("CheckType"); 20 } 21 } 22 23 private CheckType _testchecktype; 24 /// <summary> 25 /// 选项类型 26 /// </summary> 27 public CheckType TestCheckType 28 { 29 get { return _testchecktype; } 30 set 31 { 32 _testchecktype = value; 33 RaisePropertyChangedEvent("TestCheckType"); 34 } 35 } 36 37 }
初始化ViewModel，后台代码：
1 DataContext = new ViewModel() 2 { 3 TestCheckType = CheckType.SingleChecked, 4 SettingListsSingle = new List<setmodel>() { 5 new setmodel() { 6 GroupName="GN0", 7 Name="选中类型", 8 TgLists =new ObservableCollection<tgmodel>() 9 { new tgmodel() { Content="多选"}, 10 new tgmodel() { Content="行单选"}, 11 new tgmodel() { Content="全部单选" ,IsChecked=true }, 12 }}, }, 13 CheckType = CheckType.RowChecked, 14 SettingLists = new List<setmodel>() { 15 new setmodel() { 16 GroupName="GN1", 17 Name="测试数字", 18 TgLists =new ObservableCollection<tgmodel>() 19 { new tgmodel() { Content="Test1"}, 20 new tgmodel() { Content="Test2"}, 21 new tgmodel() { Content="Test3"}, 22 new tgmodel() { Content="Test4"}, 23 new tgmodel() { Content="Test5",IsChecked=true}, 24 }}, 25 new setmodel() { 26 GroupName ="GN2", 27 Name="测试字母", 28 TgLists =new ObservableCollection<tgmodel>() 29 { new tgmodel() { Content="TestA"}, 30 new tgmodel() { Content="TestB"}, 31 new tgmodel() { Content="TestC"}, 32 new tgmodel() { Content="TestD"}, 33 new tgmodel() { Content="TestE",IsChecked=true}, 34 }}, 35 new setmodel() { 36 GroupName="GN3", 37 Name="测试假名", 38 TgLists =new ObservableCollection<tgmodel>() 39 { new tgmodel() { Content="Testあ"}, 40 new tgmodel() { Content="Testい"}, 41 new tgmodel() { Content="Testう"}, 42 new tgmodel() { Content="Testえ"}, 43 new tgmodel() { Content="Testお",IsChecked=true}, 44 }}, 45 } 46 };
最后是命令的初始化：
1 var Vm = (DataContext as ViewModel); 2 3 Vm.SettingLists.ForEach(setmodel => setmodel.TgLists.ToList().ForEach( 4 (tgmodel=> tgmodel.CheckedCommand = new RelayCommand((pars) => 5 { 6 TgInfo info = new TgInfo 7 { 8 RowName = pars.ToString(), 9 SetModel = setmodel, 10 TgModel = tgmodel 11 }; 12 SetTgStatus(info, Vm,Vm.CheckType, Vm.SettingLists); 13 })))); 14 15 16 17 Vm.SettingListsSingle.ForEach(setmodel => setmodel.TgLists.ToList().ForEach( 18 (tgmodel => tgmodel.CheckedCommand = new RelayCommand((pars) => 19 { 20 TgInfo info = new TgInfo 21 { 22 RowName = pars.ToString(), 23 SetModel = setmodel, 24 TgModel = tgmodel 25 }; 26 SetTgStatus(info, Vm, Vm.TestCheckType, Vm.SettingListsSingle); 27 }))));
设置命令实现如下：这里只是我的实现。
1 /// <summary> 2 /// 设置选中状态 3 /// </summary> 4 /// <param name="pars"></param> 5 /// <param name="Vm"></param> 6 private void SetTgStatus(params object[] parms) 7 { 8 var tginfo = parms[0] as TgInfo; 9 var tgmodel = tginfo.TgModel; 10 var rowname = tginfo.RowName; 11 var setmodel = tginfo.SetModel; 12 var Vm = parms[1] as ViewModel; 13 var checktype = (CheckType)parms[2]; 14 var settings = parms[3] as List<setmodel>; 15 if (setmodel.Name=="选中类型") 16 { 17 var index = setmodel.TgLists.IndexOf(tgmodel); 18 Vm.CheckType = this[index]; 19 } 20 if (checktype == CheckType.RowChecked) 21 { 22 settings.ForEach(sets => 23 sets.TgLists.Where 24 (t => rowname == sets.GroupName&& t!=tgmodel).ToList(). 25 ForEach(tg => tg.IsChecked = false)); 26 } 27 else if (checktype == CheckType.SingleChecked) 28 { 29 settings.ForEach(sets => 30 sets.TgLists.Where(t=>t!=tgmodel).ToList(). 31 ForEach(tg => tg.IsChecked = false)); 32 } 33 else 34 { 35 36 } 37 }
其中CheckType 用到了索引器，实现如下：
1 public CheckType this[int index] 2 { 3 get 4 { 5 return index == 0 ? CheckType.MutilChecked : 6 (index == 1 ? CheckType.RowChecked : 7 CheckType.SingleChecked); 8 } 9 10 set 11 { 12 } 13 }
5，运行，OK。有什么问题可以一起讨论！
现在开始坚持每天一贴！也算是项目经验的总结和分享吧。当然肯定有很多不足之处，希望大家多多指教！
