我有一个扩展的

可观测集合

，它保存数据点和一些额外的信息

public class ExtendedCollection : ObservableCollection<KeyValuePair<string, int>>
{
    public string dateStamp { get; set; }
}

最后，我尝试在每个数据点列中模板化的标签上显示集合的属性

日期戳
<chartingToolkit:ColumnSeries Name="columnSeries" DependentValuePath="Value" IndependentValuePath="Key" ItemsSource="{Binding ColumnValues}">
    <chartingToolkit:ColumnSeries.DataPointStyle>
        <Style TargetType="chartingToolkit:ColumnDataPoint">
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="chartingToolkit:ColumnDataPoint">
                        <Grid>
                            <Grid.RowDefinitions>
                                <RowDefinition Height="30" />
                                <RowDefinition Height="*" />
                            </Grid.RowDefinitions>
                            <Label Grid.Row="0" Content="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type chartingToolkit:ColumnSeries}},Path=dateStamp, Mode=TwoWay}"></Label>
                        </Grid>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>
    </chartingToolkit:ColumnSeries.DataPointStyle>
</chartingToolkit:ColumnSeries>



我已经为标签内容尝试了许多不同的绑定
，但没有一个有效
尝试将绑定路径更改为“DataContext.ColumnValues.dateStamp”：


<chartingToolkit:ColumnSeries Name="columnSeries" DependentValuePath="Value" IndependentValuePath="Key" ItemsSource="{Binding ColumnValues}">
    <chartingToolkit:ColumnSeries.DataPointStyle>
        <Style TargetType="chartingToolkit:ColumnDataPoint">
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="chartingToolkit:ColumnDataPoint">
                        <Grid>
                            <Grid.RowDefinitions>
                                <RowDefinition Height="30" />
                                <RowDefinition Height="*" />
                            </Grid.RowDefinitions>
                            <Label Grid.Row="0" Content="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type chartingToolkit:ColumnSeries}},Path=dateStamp, Mode=TwoWay}"></Label>
                        </Grid>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>
    </chartingToolkit:ColumnSeries.DataPointStyle>
</chartingToolkit:ColumnSeries>

<Label Grid.Row="0" Content="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type chartingToolkit:ColumnSeries}},Path=DataContext.ColumnValues.dateStamp, Mode=TwoWay}" />
