Hello Abs,

Correct. ItemToolTipLayer is restricted to our charting components only. Let me know if you have any questions regarding this matter.

Thanks Michael, I have managed to create a nested style for tooltip as suggested and serving the purpose however I assume it does not support ItemToolTipLayer which is supported by XamDataChart.Series

Hello Abs,

Thank you for following up. You can add a nested style for Tooltip as a resource for DiagramNode and go as far as changing the entire template.

eg.

<Style TargetType="{x:Type ig:DiagramNode}"
                x:Key="EmpNode"
               BasedOn="{StaticResource {x:Type ig:DiagramNode}}">
            <Style.Resources>
                <Style TargetType="ToolTip">
                    <Setter Property="Background" Value="Red"/>
                    <Setter Property="Template">
                        <Setter.Value>
                            <ControlTemplate TargetType="ToolTip">
                                <Grid>
                                    <Ellipse Fill="{TemplateBinding Background}"/>
                                    <ContentPresenter HorizontalAlignment="Center"
                            VerticalAlignment="Center"/>
                                </Grid>
                            </ControlTemplate>
                        </Setter.Value>
                    </Setter>
                </Style>
            </Style.Resources>
        </Style>

Let me know if you have any questions regarding this matter.

Thank you for your response on how to set bind tooltip to property of node's object. However, my query was re-restyling it, is it possible define "tooltipstyle" to show like a call out tooltip?
