How to make the ToolTip display multiple values.
posted

I'm binding my xamchart of type Area  to a list containing 3 values which are months,balance and interest.

I have set the Datamapping as Value=Balance and Label = Month.

I want the tooltip on the datapoint to show balance aswell as interest. I know i can set the ToolTip = Interest in Datamapping, but i also want to show the Balance. Is there anyway by which i can access the datasource from the tooltip's datatemplate and then display all the values.I tried some options like the one below but didnt work.

Please help.

Thanks. 

<!-- Chart Series -->

<igCA:XamChart.Series>

<igCA:Series ChartType="Area"

DataSource="{Binding Path=MonthlyAccountList}"

DataMapping="Value=Balance;Label=Month;ToolTip=Interest">

</igCA:Series>

</igCA:XamChart.Series>

<!-- ToolTip Style-->

<Style TargetType="ToolTip">

<Setter Property="FontSize" Value="15" />

<Setter Property="Template">

<Setter.Value>

<ControlTemplate TargetType="ToolTip">

<Border BorderBrush="Black"

BorderThickness="1"

Background="LightGray">

<Grid DataContext="{Binding  RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type igCA:Series}}}">

<Grid.ColumnDefinitions>

<ColumnDefinition/>

<ColumnDefinition/>

</Grid.ColumnDefinitions>

<Grid.RowDefinitions>

<RowDefinition/>

<RowDefinition/>

<RowDefinition/>

</Grid.RowDefinitions>

<TextBlock Style="{StaticResource TextBlockStyle}"

Grid.Row="0"

Grid.Column="0"

Text="Account Balance:"/>

<Label Style="{StaticResource DollarLabelStyle}"

Grid.Row="0"

Grid.Column="1"

Content="{Binding Balance}"/>

<TextBlock Style="{StaticResource TextBlockStyle}"

Grid.Row="1"

Grid.Column="0"

Text="Interest Amount:"/>

<Label Style="{StaticResource DollarLabelStyle}"

Grid.Row="1"

Grid.Column="1"

Content="{Binding Interest}"/>

</Grid>

</Border>

</ControlTemplate>

</Setter.Value>

</Setter>

</Style>

     that is an interesting approach, but I'm afraid it won't work because the DataContext is never set on the tooltip objects that get created by the chart.

    you can make a feature request here: http://devcenter.infragistics.com/protected/requestfeature.aspx

    the only workaround I can think of is to add a string property on your data objects that return the full tooltip string, and add that new property to your DataMapping.
