Hello,

Thank you for your post.

I was researched the functionality that you want to achieve and it seems that the XamDockManager currently does not provide an event that you can use to track the change in the location of the ContentPanes. Would you please provide me with  more details about  your requirements, in order to be able to research  for alternative approach?

Looking forward to hearing from you.

I can suggest you also see the follow forum thread from this link: http://ko.infragistics.com/community/forums/p/32103/175463.aspx#175463, which discuss the same issue.
