Power Pages currently does not provide a platform-level auto-save capability for Basic Forms (Dataverse Forms), unlike model-driven apps which support periodic background auto-save (e.g., every 30 seconds). 

In Power Pages: 

• Data has persisted only on explicit form submission 
• Partial user input is lost if the page is refreshed, navigated away from, or the browser session ends 
• There is no built-in support for draft saving, background persistence, or resume capability 
• Dataverse table auto-save behavior does not reliably apply to Power Pages scenarios 

This limitation creates usability and data-loss risks for: 

• Long forms 
• External users 
• Citizen-facing portals 
• Scenarios with intermittent connectivity 

Requested Enhancement 

Introduce a platform-level auto-save option for Power Pages Basic Forms, similar to model-driven apps, with characteristics such as: 

• Configurable auto-save interval 
• Draft record creation and update 
• Resume-incomplete-form support 
• No requirement for custom JavaScript or Web API implementation 

This would significantly reduce custom development, improve user experience, and align Power Pages behavior with other Dataverse-based applications.
