Hello Smartpcr,

The current BETA version supports multiple item selection only -- we will be extending the ChartSelectionBehavior with series selection and the ability to specify single item/series selection for the Q1 2012 official release.

Here is a sample code snippet that demonstrates how you can enable the chart selection:

• Add ChartSelectionBehavior instance to the RadCartesianChart.Behaviors collection.
• Define the desired selection color via custom ChartPalette and set it to the RadCartesianChart.SelectionPalette property.
• You can detect the selection actopn via the RadCartesianChart.SelectionChanged event.

Hi Telerik,

I have been using the new chart engine and I must admit it is so much more simple than the previous one.

I have implemented the selection behavior and it works well, I can click on any of my bar and raise the selection event.

Nevertheless, I am trying now to find a way to select on of the bar (from my BarSeries) from code and not from mouse click anymore.

I tried to set the selectionPoints in the code manually without success.

Can you tell me how to select one single bar from code ?

Thanks !

Up ;)

Hello Sofie,

RadChart.SelectionPoints is a read-only collection that is generally useful if you would like to use the chart selection in a different control (i.e. you will bind ListBox.ItemsSource to RadChart.SelectionPoints).

You can use the respective DataPoint.IsSelected boolean property to achieve the desired effect:

Hope this helps.

Which future release support selection behavior on chart series? thanks!

Hello Xiaodong,

Could you elaborate a bit more on the desired selection behavior -- if you are looking for series-wide selection e.g. for a LineSeries to highlight the whole polyline in a different color, unfortunately this functionality is not available yet.
