Question

I need to be able to specify a command to run when the SelectionChanged event fires. I already know how to implement the ICommandSource interface; what I need to know is how I can just add a command to the column series to handle the SelectionChanged event.

When I inherit from the ColumnBarBaseSeries<…> base class I have to override GetAxes() and UpdateDatePoint() which I am not sure how to implement.

Answer 1

You can use attached behaviours to solve this problem.

Create a SelectionChangedBehaviour that wires a selectionChanged event to the element that you’re attaching the behaviour to then you can binding any ICommand to that behaviour.
