I have   a Splinearea chart with a customized tooltipStyle and two series.

Everything is dispalyed correctly. But if I add an ItemTooltipLayer to allow the simultaneous display of the two tooltips on rollover, the style seems to be no longer active: I see the default tooltip style for both the series.

Help on this issue will be appreciated.

at the end of the series:

<ig:ItemToolTipLayer

Canvas.ZIndex="11" UseInterpolation="True" TransitionDuration="0:00:00.1">

</ig:ItemToolTipLayer>

Chart ToolTip style:

<Style x:Key="DataChartToolTipStyle" TargetType="ContentControl">

<Setter Property="Padding" Value="0,0,0,0" />

<Setter Property="Margin" Value="0,0,0,0" />

<Setter Property="Template">

<Setter.Value>

<ControlTemplate TargetType="ContentControl">

<Border CornerRadius="4" BorderThickness="1,1,1,1" BorderBrush="{StaticResource BurshToolTipBorder}" Background="{StaticResource BurshToolTipBackground}">

<StackPanel Orientation="Horizontal" Margin="2,2,2,2">

<ContentPresenter Margin="{TemplateBinding Padding}" Content="{TemplateBinding Content}" />

</StackPanel>

</Border>

</ControlTemplate>

</Setter.Value>

</Setter>

</Style>
