You can try to add the events by using EventSetters in the styles for PieDataPoints.
Alternatively, there are locations in the source code for the pie labels where I have access to the actual PieDataPoints (such as in the IsLabeledPropertyChanged method) and that can be used to add the event handler programatically.

Hope this helps.

If you’re using the latest version of the toolkit, the code I have in this post may not work correctly. There were some breaking changes and some new features (such as unsealing the classes I needed) that allow the code here to be a lot simpler (you can read more about that in David’s blog). I plan to update this code to the latest toolkit and blog about it – just haven’t had a chance to get to that yet.

So, it may be that the issues you’re having in VB are also present in C#. If they’re unrelated, then I’m afraid I’m not a VB expert, so I’m not the best person to help you.

Stay tuned for an updated version of this code.

Little question. Ever come across code to add a dragenter event to a piedatapoint slice? Or else, a way to enumerate through all the piedatapoints. Stupidly enough there’s a LegendItems collection and an Itemsource to get to the bound data, but not a collection for the created pie slices (or I must be the one being stupid….)

Anyway…thanks a lot in any case for this lovely example of changing the pie.
