Updating display in a form

Refreshing records only updates the data that already exists in your datasheet or form.

It does not reorder records, display new records, or remove deleted records and records that no longer meet specified criteria.

Forms are also a relatively secure way of sharing data with the server, as they allow us to send data in requests with cross-site request forgery protection. Developers need to write HTML for the form, validate and properly sanitize entered data on the server (and possibly also in the browser), repost the form with error messages to inform users of any invalid fields, handle the data when it has successfully been submitted, and finally respond to the user in some way to indicate success.

Developers need to write HTML for the form, validate and properly sanitise entered data on the server (and possibly also in the browser), repost the form with error messages to inform users of any invalid fields, handle the data when it has successfully been submitted, and finally respond to the user in some way to indicate success.
