我正在尝试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
这是我的XAML
SEARCH_DIR
该类绑定到控件
<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>
谁能看到我做错了什么?
提前致谢!
答案 0 :(得分:0)
你的AllTags列表是否有isZero成员?(在模型中)
如果是的话
试试这个
Binding="{Binding Path=IsZero, {RelativeSource FindAncestor, AncestorType={x:Type xctk:CheckComboBox}} }"
如果不是,那么在你的datacontext类中尝试删除RelativeSource={RelativeSource Self}
