Is there any event I can get to tell me when I have clicked on an area of the chart that is not one of the pie/donut data points? There does not appear to be a selection changed to nothing state.
Also I think the object browser help text is wrong for RadChartView.DrillNavigationMode:
Public Property DrillNavigationMode As Telerik.WinControls.UI.DrillNavigationMode
Member of Telerik.WinControls.UI.RadChartView
Summary:
Show or hide Smart labels controller in RadChartView.
