Webix Filemanager Rename - Prevent special chars

When renaming a file/folder is it possible to prevent the use of certain characters?

eg. forward slash as part of file/folder name ?

Hello,
You can use onBeforeEditStop event handler to implement your own logic.
Returning false from the handler will prevent switching to the next cell.

Thanks annazankevich!

That does the trick , and I have learned a new event handler. Cheers
