I have placed a RadTreeView control in a web application that I created. I am trying to test the control for the first time, and I am receiving an error page when the control attempts to render. The error is:$0$0$0$0Method not found: 'BooleanSystem.Web.UI.ScriptManager.get_LoadScriptsBeforeUI()'.$0$0$0$0$0$0I have searched (Google) for the method "get_LoadScriptsBeforeUI()", and I have not found anything. The closest thing I found was the "LoadScriptsBeforeUI" property, which is described in MSDN.$0$0$0$0$0Does anyone have any suggestions as to how I can debug/fix this?$0$0$0$0$0Thanks$0$0$0$0$0Also...I am getting mysterious "There is an error in XML document (1, 145)" messages when I attempt to use the LoadXml function of the RadTreeView. The XML I am attempting to load is valid and can be viewed in an XML viewer. If I put in a very simple XML string like:$0$0$0$0$0"<Tree><Node AccessKey='0' Value='0' Text='VectorCSP WPM'></Node></Tree>" $0$0$0$0$0$0$0$0$0$0it seems to work. But a larger one, with many, many more nodes, does not. I can't seem to pin point the problem here, either.$0$0$0$0$0Any help would really be appreciated.$0$0Thank you.$0$0$0$0
