# Global Event: OnRenameFolderStart

The OnRenameFolderStart Event occurs when a user attempts to rename a folder. This event happens before the folder is renamed permitting you to stop the renaming if desired.

Signature

For custom code the args array is structured as follows:

args[] is contains two strings, the first represents the fully qualified current folder name, the second is the new folder name.

For .Net Assemblies the method signature is as follows:

string EventHandlerName(SessionInfo sessionInfo, string currentFolderName, string newFolderName)

Expected Return

The OnRenameFolderStart Event expects a string to be returned. Based on the returned string there are three possible results.

- Null / Whitespace – If the string is null or whitespace then the report execution will continue as expected.
- LanguageId – If the string matches the id of any element in the language files then the string of that language element will be displayed as a message to the user. For more information see Multi-Language Support.
- Other – If the string does not match the id of any element in the language files then the returned value will be displayed as a message to the user.
