wpf属性更新后通知的问题

[swtee]

问题：两个checkbox更新后，绑定的属性并没有更新，请教各位大神带这么解决？只有200分，如果哪位能解决，全部奉上
代码如下：
view(XAML文件)：
<UserControl.Resources>
<ResourceDictionary>
<local:ShowConverter x:Key="sc"/>
</ResourceDictionary>
</UserControl.Resources>
<CheckBox Content="{Binding BSM.Commander_BTNMain.Name}" IsChecked="{Binding BSM.Commander_BTNMain.IsSelected}" >
<CheckBox Content="{Binding BSM.Commander_BTNSub.Name}" Grid.Column="1" IsChecked="{Binding BSM.Commander_BTNSub.IsSelected}" />
<Label>
<Label.Content>
<Label Grid.Column="1">
<Label.Content>
<MultiBinding Converter="{StaticResource sc}">
<Binding Path="BSM.Commander_BTNMain" Mode="OneWay"/>
<Binding Path="BSM.Commander_BTNSub"/>
</MultiBinding>
</Label.Content>
</Label>
Model:
public class ICheckItem : BindableBase
{
/// <summary>
///当前项是否选中
///</summary>
private bool isSelected;
public bool IsSelected
{
get { return isSelected; }
set
{
SetProperty(ref isSelected, value);
}
} /// <summary>
///名称
///</summary>
public string Name { get; set; }
}

public class BTNSysDeployModel : BindableBase
{ //主车
private ICheckItem commander_BTNMain = new ICheckItem();

public ICheckItem Commander_BTNMain
{
get { return commander_BTNMain; }
set
{
SetProperty(ref commander_BTNMain, value);
}
}
//副车
private ICheckItem commander_BTNSub = new ICheckItem();

public ICheckItem Commander_BTNSub
{
get { return commander_BTNSub; }
set
{
SetProperty(ref commander_BTNSub, value);
}
}
}
转换器：
public class ShowConverter : IMultiValueConverter
{
public object Convert(object[] values, Type targetType, object parameter, CultureInfo culture)
{
string show = "";
foreach (var item in values)
{
if (item is ICheckItem)
{
ICheckItem ic = (ICheckItem)item;
if (ic.IsSelected)
{
show += ic.Name + " ";
}
}
}

return show;
}

public object[] ConvertBack(object value, Type[] targetTypes, object parameter, CultureInfo culture)
{
throw new NotImplementedException();
}
}

用INotifyPropertyChanged接口更方便简单

<CheckBox Content="上传失败" IsChecked="{Binding SearchInterfaceLogIsNotSuccess, UpdateSourceTrigger=PropertyChanged}" Style="{StaticResource AlignmentCheckBoxStyle}" Canvas.Left="664" Canvas.Top="25" Width="92" Height="18"/>

        int searchInterfaceLogIsNotSuccess = 0;
        public int SearchInterfaceLogIsNotSuccess
        {
            get
            { return searchInterfaceLogIsNotSuccess; }
            set
            {
                if (searchInterfaceLogIsNotSuccess != value)
                {
                    searchInterfaceLogIsNotSuccess = value;
                    OnPropertyChanged(nameof(SearchInterfaceLogIsNotSuccess));
                }
            }
        }

 public class MainViewModel : INotifyPropertyChanged

        public event PropertyChangedEventHandler PropertyChanged;
        public void OnPropertyChanged(string propertyName)
        {
                PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
        }

IsChecked返回是整型

[ilikeff8]

我程序里返回要用整形，所以定义为int，会自动转换，searchInterfaceLogIsNotSuccess定义成bool也可以

        }

1.BindableBase和INotifyPropertyChanged是用是一样的，项目组要求使用前者；
2.情况不一样，您绑定的是一个int类型的属性，我的控件绑定的是一个引用类型的属性
我的问题简单的可以表达为如：
<Label Grid.Row="1" Name="linkLable" Content="{Binding Stu,Converter={StaticResource sc}}" HorizontalAlignment="Center" VerticalAlignment="Center"/ >
private Student _stu = new Student();

public Student Stu
{
get { return _stu; }
set { SetProperty(ref _stu, value); }
}

public class Student : BindableBase
{
private string _name;
public string Name
{
get
{
return _name;
}
set
{
SetProperty(ref _name, value);
}
}
int _age;
public int Age
{
get
{
return _age;
}
set
{
SetProperty(ref _age, value);
}
}
}

自顶，求大神

BindableBase 这玩意我用过 你要确定 是否特定场景才没收到通知？这是个坑
改用INotify就ok了

INotifyPropertyChanged，还有前端绑定里设置一下mode=twoway
