I have a project similar to the PageFlakes demo in the ASP.NET side, and when I add a control to the page, everything is fine.
however, when I close the page and re-open it, the controls are re-added to the page automatically. When this happens, I get a Jscript error in WebResource.axd on this line
that says this.GroupPanelObject.Items.length is null or not an object
I plan to switch to Prometheus Grid when my license gets renewed, but any solution for this?
