I am having an issue with this.  I am using the suggested xaml, but the tooltip appears on the grid displaying the first node's data, not on the nodes and it doesn't change location or data when I move from node to node.

Hello,

Do you have a sample illustrating your issue? I tested this and it the behavior is is expected.

Please see attached sample.
