Thank you for the additional information provided.
Based on that we have reproduced the problem. After a careful investigation of the case, we can confirm that there is a bug in the functionality of the RadNavigation control. More specifically, the control does not dispose itself appropriately.
We have added the bug to our backlog, so you can track its status in our Feedback portal
. As a temporary workaround you could implement the following override of the RadNavigation dispose() client side object method:
element = $telerik.$(
Attached you will find a simple implementation of your scenario, including the above override.
As a token of gratitude for the reported bug we have updated your Telerik points.
