NOTE: The features described are for use with the Classic-style Form Builder. If you are using the SharePoint Modern experience, our recommendation is to use the newer Form designer tool – validation is one of the functions controlled as a part of that, rather than as a stand-alone.
Infowise Column validation settings allow for dynamically applied validation that enforces specific user input based on specific rules. By using multiple conditions and pattern matching it is possible to achieve validation rules unlike anything provided in out-of-the-box SharePoint.
