WPF DataTrigger 没有触发 NotifyProperyChanged?

WPF DataTrigger not firing on NotifyProperyChanged?

我试图根据绑定它的对象中的布尔标志动态隐藏我的 ComboBox 中的元素,但我似乎无法让它工作

这是我XAML

<xctk:CheckComboBox Name="TagsDropDown" HorizontalAlignment="Left" Height="30" Margin="0,0,0,0" VerticalAlignment="Top" Width="450" IsEditable="True"  IsTextSearchEnabled="True" ItemsSource="{Binding AllTags}" ItemSelectionChanged="TagsDropDown_OnItemSelectionChanged">  
        <xctk:CheckComboBox.ItemTemplate>
            <DataTemplate>
                <Grid HorizontalAlignment="Stretch">
                    <TextBlock Margin="2" Text="{Binding Name}"/>
                    <TextBlock Margin="2" HorizontalAlignment="Right" Text="{Binding Count}"/>
                </Grid>
            </DataTemplate>              
        </xctk:CheckComboBox.ItemTemplate>
        <xctk:CheckComboBox.ItemContainerStyle>
            <Style TargetType="xctk:SelectorItem">
                <Setter Property="Visibility" Value="Visible"/>
                <Style.Triggers>
                 <!--   <DataTrigger steamTools:TriggerTracing.TriggerName="is zero" steamTools:TriggerTracing.TraceEnabled="True" Binding="{Binding Path=IsZero, RelativeSource={RelativeSource Self} }" Value="True">-->
                    <DataTrigger Binding="{Binding Path=IsZero, RelativeSource={RelativeSource Self} }" Value="True">
                        <DataTrigger.Setters>
                            <Setter Property="Visibility" Value="Collapsed"/>
                        </DataTrigger.Setters>
                    </DataTrigger>
                </Style.Triggers>
            </Style>
        </xctk:CheckComboBox.ItemContainerStyle>
    </xctk:CheckComboBox>

并且class绑定到控件

 public class CompTag : INotifyPropertyChanged
{
    private int _count;
    private bool _isZero;
    public string Name { get; set; }

    public bool IsZero
    {
        get { return _isZero; }
        set
        {
            if (_isZero != value)
            {
                _isZero = value;
                OnPropertyChanged("IsZero");
            }
        }
    }

    public int Count
    {
        get { return _count; }
        set
        {
            if (_count != value)
            {
                _count = value;
                OnPropertyChanged("Count");
            }
        }
    }

谁能看出我做错了什么?

提前致谢!

您的 AllTags 列表是否有 isZero 成员?(在模型中)

如果是

试试这个

Binding="{Binding Path=IsZero, {RelativeSource FindAncestor, AncestorType={x:Type xctk:CheckComboBox}} }"

如果没有,并且它在您的数据上下文中 class 尝试删除 RelativeSource={RelativeSource Self}
