Thank you for your inquiry.
The beta of the new SharePoint suite is available through our Forums: http://www.sharepointcontrols.com/support/forums/forums.aspx
I think it was posted last week.
As far as I know, we had a couple of customers who were using r.a.d.callback
in SPS without problems. I do not know whether they have switched to r.a.d.ajax
, but my guess is that it will work. Please, give it a spin and let us know what your initial impressions are. I will ask our developers whether they are familiar with any issues and will write back.
