Hello,
thank you for your replies.
I think what i want to do is a bit different, i tried your suggestions but didn't work.
I want to navigate to a page of portal 1 while i am in portal 0.
When i use NavigateUrl, it tries to access the page through portal 0 (current portal) and the page is not found.
I did find another way to construct the URL based on the portal, but without using NavigateUrl which would be ideal if it worked.
Thanks for the help,
M. Mourouti
