Sometimes just having to build a demo can already be really stressful. This morning I had to finish a silverlight demo for a customer that features a new concept we are building. One of the cool features is the ability to show really rich tooltip information about stuff that is on the screen. Or so I thought…

As it turns out Microsoft doesn’t set the DataContext property of the tooltip control. Rendering databinding completely useless. Luckely people in the community have come up with a very good solution to this problem: http://www.wiredprairie.us/blog/index.php/archives/568

So it’s back to my demo and fix this last problem, before showing it to the public ;)
