How to Use Virto SharePoint List Form Extender Web Part for Smarter Forms

1. onLoad: set visibility for “Budget Details” and default “Project Manager”.
2. onChange(“Has Budget”): toggle Budget fields.
3. onChange(“Project Type”): if “External”, mark “Client Name” required and enable API validation on blur.
4. onSave: run validators; if client validation pending, block save until resolved.

Common pitfalls

• Overcomplicating UI with too many scripts—prefer staged rollouts.
• Not accounting for form customizations made by coworkers: always check for existing custom scripts.
• Heavy synchronous API calls on save that cause timeouts—use async validation with clear user feedback.
