Tutorial: SharePoint List Validation

This SharePoint Online tutorial will demonstrate how to list validation in a SharePoint Online. The tutorial will outline what SharePoint list validation is, how it differs from SharePoint list column validation and then will demo several examples of how to implement list validation including:

•  SharePoint validation that ensures that the value being entered in a date column (Project End Date) is greater than the Start Date
• SharePoint list validation that ensures that the value being entered in a number type column (Project Contingency) is less than the value in another number type column (Project Budget)
• SharePoint list validation that enforces that a field is required based on the value of another column. For example, if a project budget is greater than 500, then a text column called project justification must be populated.
