Thank you for contacting us.
Currently, RadSpreadsheet does not have a mechanism to suppress the warning messages. For this reason, we have introduced a MessageShowing event to the RadSpreadsheet class that allows you to prevent the alerts displayed to the user. For example, the following snippet will suppress all protection errors:
sender, MessageShowingEventArgs e)
content = LocalizationManager.GetString(
Please note that the event will be included in the LIB expected next week.
Let me know if you have further queries. I will do my best to assist you.
