Each time an item is going to be deleted, the ItemDeleting event occurs, allowing you to cancel the action. You can use the event parameter’s properties to identify a name (ASPxClientFileManagerActionEventArgsBase.name) or a full name (ASPxClientFileManagerActionEventArgsBase.fullName) of the deleted item. The ASPxClientFileManagerActionEventArgsBase.isFolder property indicates the type of a currently being deleted item: file or folder.
To cancel the delete operation, set the ASPxClientFileManagerItemEditingEventArgs.cancel property to true
.
After an item has been deleted, the ASPxClientFileManager.ItemDeleted event is raised.
