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：

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 }
View Code
![]()
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 }
View Code
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！
