私はこの状況を持っています：
カスタム コンポーネントのツールチップのスタイルを定義しました。
<Style x:Key="ToolTipPieChart" TargetType="{x:Type ToolTip}">
<Setter Property="Opacity" Value=".95" />
<Setter Property="Template">
<Setter.Value>
<!-- modify the tooltip control template to add a drop shadow-->
<ControlTemplate TargetType="{x:Type ToolTip}">
<Grid Background="Transparent" Margin="5" Width="{TemplateBinding Width}" Height="{TemplateBinding Height}">
<Rectangle Fill="White" Height="{TemplateBinding Height}" RadiusX="7.5" RadiusY="7.5">
<Rectangle.BitmapEffect>
<DropShadowBitmapEffect ShadowDepth="3"/>
</Rectangle.BitmapEffect>
</Rectangle>
<ContentPresenter Margin="5" HorizontalAlignment="Center" VerticalAlignment="Center" />
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
<Setter Property="ContentTemplate">
<Setter.Value>
<DataTemplate>
<!-- bind the stack panel datacontext to the tooltip data context -->
<StackPanel Orientation="Horizontal"
DataContext="{Binding Path=DataContext, RelativeSource={RelativeSource AncestorType={x:Type ToolTip}}}">
<!-- navigate to the pie piece (which is the placement target of the tooltip) and obtain the percentage -->
<TextBlock FontSize="30" FontWeight="Bold" Margin="0,0,5,0"
DataContext="{Binding Path=PlacementTarget, RelativeSource={RelativeSource AncestorType={x:Type ToolTip}}}"
Text="{Binding Path=Percentage, Converter={StaticResource formatter}, ConverterParameter='\{0:0%\}'}"/>
<StackPanel Orientation="Vertical">
<TextBlock FontWeight="Bold" Text="{Binding Path=AFCDENTE}"/>
<!--<StackPanel Orientation="Horizontal">
<TextBlock Name="_txbEnte" Text="AFCDENTE"/>
<TextBlock Text=": "/>
<TextBlock Text="{Binding Path=AFCDENTE}"/>
</StackPanel>-->
<StackPanel Orientation="Horizontal">
<TextBlock Name="_txbModGen" Text="Modgen"/>
<TextBlock Text=": "/>
<TextBlock Text="{Binding Path=Modgen}"/>
</StackPanel>
<StackPanel Orientation="Horizontal">
<TextBlock Name="_txbAggAlter" Text="AggAlter"/>
<TextBlock Text=": "/>
<TextBlock Text="{Binding Path=AggAlter}"/>
</StackPanel>
<StackPanel Orientation="Horizontal">
<TextBlock Name="_txbAggTolt" Text="AggTolt"/>
<TextBlock Text=": "/>
<TextBlock Text="{Binding Path=AggTolt}"/>
</StackPanel>
<StackPanel Orientation="Horizontal">
<TextBlock Name="_txbModDis" Text="ModDis"/>
<TextBlock Text=": "/>
<TextBlock Text="{Binding Path=ModDis}"/>
</StackPanel>
<StackPanel Orientation="Horizontal">
<TextBlock Name="_txbModPar" Text="ModPar"/>
<TextBlock Text=": "/>
<TextBlock Text="{Binding Path=ModPar}"/>
</StackPanel>
<StackPanel Orientation="Horizontal">
<TextBlock Name="_txbCamPrior" Text="CamPrior"/>
<TextBlock Text=": "/>
<TextBlock Text="{Binding Path=CamPrior}"/>
</StackPanel>
<StackPanel Orientation="Horizontal">
<TextBlock Name="_txbCamCL" Text="CamCL"/>
<TextBlock Text=": "/>
<TextBlock Text="{Binding Path=CamCL}"/>
</StackPanel>
<StackPanel Orientation="Horizontal">
<TextBlock Name="_txbCamMat" Text="CamMat"/>
<TextBlock Text=": "/>
<TextBlock Text="{Binding Path=CamMat}"/>
</StackPanel>
<StackPanel Orientation="Horizontal">
<TextBlock Name="_txbModTTechP" Text="ModTTechP"/>
<TextBlock Text=": "/>
<TextBlock Text="{Binding Path=ModTTechP}"/>
</StackPanel>
<StackPanel Orientation="Horizontal">
<TextBlock Name="_txbModTRianL" Text="ModTRianL"/>
<TextBlock Text=": "/>
<TextBlock Text="{Binding Path=ModTRianL}"/>
</StackPanel>
</StackPanel>
</StackPanel>
</DataTemplate>
</Setter.Value>
</Setter>
</Style>
そして、ここに私のコンポーネントがあります:
<PieChart:PieChartLayout HorizontalAlignment="Center" Grid.Row="0" Grid.Column="0"
x:Name="piePlotter" PlottedProperty="Totale" DisplayProperty="AFCDENTE" Margin="10">
<PieChart:PieChartLayout.ColorSelector>
<PieChart:IndexedColourSelector Brushes="{StaticResource brushes}"/>
</PieChart:PieChartLayout.ColorSelector>
<PieChart:PieChartLayout.ToolTip>
<ToolTip Style="{StaticResource ToolTipPieChart}" />
</PieChart:PieChartLayout.ToolTip>
</PieChart:PieChartLayout>
スタイルは適用されません。なぜあなたの意見では？私は何をすべきか？
