ElementName vs. RelativeResource?

Question

What of the following TextBlocks\' Bindings costs more performance:

Answer 1

The later of the two needs to walk the visual tree looking for a particular ancestor type, where as the prior looks directly to the window's namescope for a registered object with that name...my guess would be the later is marginally slower...that said, I don't think there will be a significant performance difference.

Hope it helps,
