SF-0117

Impact #

Data grids display many records with editable fields. Data grids frequently expand to thousands of input components on a page and exceed the maximum view state size, resulting in a Visualforce component tree that’s slow to process.

Remediation #

If your Visualforce page needs a data grid:

• Use pagination and filters.
• Where possible, make data read-only to reduce the view state size.
• Only display essential data for a given record, and provide a link for an Ajax-based details box or separate page to view the rest
