  To reproduce this error, at least I believe it to be an error since eg.
  
  http://helpcentral.componentone.com/nethelp/Flexchartwpf/TreeMapSelection.html

  is showing that it should work.

  To reproduce the error, I took the sample from here
  
  \ComponentOne Samples\ComponentOne Samples\WPF.Net 5\CS\Chart\FlexChartExplorer

  And modiefied the file
  
  View\TreeMap.xaml

  To this:

  
  <Chart:C1TreeMap x:Name="treeMap" Grid.Row="1" MaxDepth="2" Binding="sales" BindingName="type" ChildItemsPath="items"
                   ItemsSource="{Binding DataContext.Data}" 
                   SelectionChanged="TreeMap_OnSelectionChanged"
                   SelectionMode="Point">
      <Chart:C1TreeMap.DataLabel>
          <Chart:DataLabel Content="{}{type}" Position="Center"/>
      </Chart:C1TreeMap.DataLabel>
  </Chart:C1TreeMap>
  
  

  Notice the added members SelectionChanged and SelectionMode.

  In the file
  
  View\TreeMap.xaml.cs

  I have added this eventhandler

  
  private void TreeMap_OnSelectionChanged(object? sender, EventArgs e)
  {
      
  }
  
  

  Now put a breakpoint in the eventhandler, open the demo and click on any item in the C1TreeMap, the breakpoint will never hit.

  My version I am currently demo-ing is 5.0.20203.34.
