<p>I am using WPF Toolkit to draw a line chart (a feature on our application). Given a Collection, I am able to plot the graph, however, when the user double clicks on the DataPoint on the graph, I am finding it difficult to get the X and Y data value (not the Co-Ordinate value in the line graph).</p> <p>I am able to set property using DataPointStyle, but unable to add event to it.</p> <p>If I use <code>MouseDoubleClick="lineChart_ShowResults_DoubleClick"</code> property on the LineSeries node, then it triggers an event when user clicks on any point. But, I need to trigger the event <strong>only</strong> if the user clicks on the DataPoint. The following is the XAML that I tried to implement. Please help.</p> <pre><code><Window x:Class="TeamXXX.YYYUI.GraphicalDisplay" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="GraphicalDisplay" Height="400" Width="600" xmlns:chartingToolkit="clr-namespace:System.Windows.Controls.DataVisualization.Charting;assembly=System.Windows.Controls.DataVisualization.Toolkit" mc:Ignorable="d" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" d:DesignHeight="439" d:DesignWidth="654" SizeToContent="WidthAndHeight"> <ScrollViewer HorizontalScrollBarVisibility="Auto" VerticalScrollBarVisibility="Auto"> <Grid MinHeight="360" MinWidth="575" HorizontalAlignment="Stretch" VerticalAlignment="Stretch"> <chartingToolkit:Chart Name="lineChart" HorizontalAlignment="Stretch" VerticalAlignment="Stretch"> <chartingToolkit:Chart.LegendStyle> <Style TargetType="Control"> <Setter Property="Height" Value="0" /> <Setter Property="Width" Value="0" /> </Style> </chartingToolkit:Chart.LegendStyle> <chartingToolkit:LineSeries DependentValuePath="Value" Name="lineSeries" IndependentValuePath="Key" ItemsSource="{Binding}" IsSelectionEnabled="True" MouseDoubleClick="lineChart_ShowResults_DoubleClick">  <chartingToolkit:LineSeries.DependentRangeAxis> <chartingToolkit:LinearAxis Orientation="Y" Title="Cost in minutes" FontSize="16" /> </chartingToolkit:LineSeries.DependentRangeAxis> <chartingToolkit:LineSeries.IndependentAxis> <chartingToolkit:LinearAxis Orientation="X" Title="Fold" FontSize="16" /> </chartingToolkit:LineSeries.IndependentAxis> </chartingToolkit:LineSeries> </chartingToolkit:Chart> </Grid> </ScrollViewer> </Window> </code></pre>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
