Restrict list editing If you create UI policies or client scripts for fields on a form, you must use another method to ensure that data in those fields is similarly controlled in a list. With the exception of onCellEdit client scripts, UI policies and client scripts apply to forms only. Use the following methods to restrict list editing when using client scripts: Disable list editing for the table. Create appropriate business rules or access controls for list editing. Create data policies. Create a separate onCellEdit client script.
