The above error occurs when there is no Syncfusion virtual directory or the using Web Server is a part of VS.NET 2005.
Note that the GridControl expects the scripts and images virtual IIS directory under the /Syncfusion/Resources/GroupingGridWeb directory. Since you are using the 2.0 Framework delete the default ImageFilesPath and ScriptFilesPath property settings (it should be empty in the property settings) to address this issue for now.
