NRectangularCallout misses the InteractivityStyle property. So how can I set a tooltip on a NRectangularCallout object? Currently I am able to set a tooltip on the whole surface of the chart control except on these annotation objects.

Thanks in advance for your help.

Hi Jerome,

This requires a small fix in the component (this property is not exposed for annotations by mistake) and we just fixed that internally. We'll issue a SP tomorrow fixing this and other issues...
