Window.BindingGroup.BindingExpressions.count=0?但是前台确实有bindinggroup RRS feed

  • 问题

  •     <Window.BindingGroup>
            <BindingGroup x:Name="bindingGroup"/>
        </Window.BindingGroup>

      <Label Width="Auto" Canvas.Left="273" Height="32" Canvas.Top="51">
                            <Label.Content>
                                <Binding Path="[/Topec/Sequencer/@SystemMode]" BindingGroupName="bindingGroup">
                                    <Binding.Converter>
                                        <cvt:SystemModeConverter />
                                    </Binding.Converter>
                                </Binding>
                            </Label.Content>
                        </Label>

    上面这样为啥后台获取BindingGroup.BindingExpressions.count=0呢?
