Can I validate the data being entered into a text box within EngageOne Server ActiveX editor?

Product Feature: Interactive Editor (ActiveX)

Operating System: Microsoft Windows

No, unfortunately it is not possible to set validation rules on a 'string' to prevent users from entering unwanted characters. The field can only be set to 'Mandatory' meaning that a value must be entered when the text box is shown in the ActiveX editor, forcing the user to enter a value before being allowed to proceed.
