Tooltip timeout

[Mattias]

Hi,
My tooltip works fine until I leave my computer for say 10 minutes.
When I come back and hoover an item to see the tooltip it just loads and loads unil it fails completely.
I really don't know where or what to look for!

I've got this from event viewer:

Hello Mattias,

I am not quite sure what is the exact problem on your side and since I do not have your code I can only assume what might cause the issue. I assume that you are using a RadToolTipManager and you are using the LoadOnDemand functionality to load content by using AJAX. If so, I think that the issue could be a known issue with the MS AJAX framework which concerns the session. The only workaround we can suggest in this case at the moment is not to let the session expire - one possible way to achieve this can be found here.

In case this is not the case on your side, please prepare a sample, fully runnable demo project, open a new support ticket and send it to me along with detailed explanation.

Kind regards,
