DESCRIPTION This message shows that the control is not able to locate the proper RadControls/[control] folder. It usually appears after updating the control to a newer version. The causes for the message to appear are:
As of RadControls Q2 2006 almost all .NET2 versions use embedded resources for their JS files, default skin, and localization files. The controls which differ from this trend and still use a RadControls folder are RadEditor, RadSpell, RadUpload, and RadWindow to some extend. More information on the topic can be found in the following Forum post: Q2 & Embedded WebResources ?
If you see the error message with the .NET2 versions of these products, please check the above two descriptions when the error can occur, as well as the solutions below on how to fix the error.
