Silverlight binding errors in the output window

I know that if there's an issue with the Path attribute in my binding expression, I'll get a bindin开发者_如何学JAVAg error message in my output window, but is there anyway to debug a ElementName attribute issue?

I have tried things that I'm pretty sure don't exist like

ElementName=ElephantButt

and get nothing in the output window.

Thanks.
