Field Constraints


Validate your SharePoint forms and make sure the user's input makes sense!

Easily configure field-validation rules to enforce input patterns according to your required form logic: Email, field length, ID, value ranges and any other custom pattern using regular expressions!
By using a simple and intuitive settings page you can quickly configure dynamic validation rules.


Validate column types that cannot be validated by SharePoint

There are column types that SharePoint does not validate. These include: Lookup and Person column types.
With the Field Constraints feature you can validate any field type.

SharePoint field validations


Validate against fixed and dynamic values

You can compare your field value to fixed values/ranges or to values of other fields in your form.
: in the following screenshot we've configured a validation rule that checks that a task is not assigned to the current user (using the [Me] token):

Validate custom patterns using Regular Expressions

Need to validate a custom patterns such as Email, social security number or credit card number? Not a problem!
You can validate any custom pattern by simply using regular expressions your new custom validation rule in a S.C repository to be used by other site owners.

Add logic to your forms with Dynamic Validation Rules

SharePoint enables you to configure Static constraints, such as making sure a mandatory field is not empty.
However, in real web forms, many times your validation rules need to change depending on the current item's context, so for example you might need to make sure a certain field is not empty, depending on the value of another field. These type of rules are Dynamic validation rules which add sense to your forms.

The Business Need

We all got used to working with SharePoint lists and document libraries. It is only natural to expect these list forms (New, Edit, View) to include all required web form features, instead of making us buy and learn a seperate Forms technology such as InfoPath or any other Forms servers.

The Field Constraints Feature is part of KWizCom Forms, which allows SharePoint customers to keep using the well-known list forms by turning them into powerful & dynamic web forms. This way there's no new technology to learn and deploy, simply keep using the same SharePoint list forms that now can include all the missing web form features.
