I just upgraded my install from q1 2010 to the most recent build (installed q1 2011 then copied over hotfix files). On formerly working code I now get layoutcycle detected. RadGridViews reside within RadExpanders and have set column widths. We use programmatic column creation. I guess I will try to isolate the problem in a side project but was wondering if anyone else had run into this issue recently and if there were quick easy fixes to try out first.
