Just wondering if it is possible to set a ribbon rule which shows/hides a button group on a form based on the certain values on that form in realtime
(I want ribbon button to be hidden if a value is missing/changed/removed from the form but before the form is saved)
While I understand that it is possible to have the ribbon run custom JavaScript, i was wondering if the JavaScript is only triggered on form load or whenever certain field values have been changed?
The refreshRibbon() function exists precisely for this purpose, and can be triggered on a field change event, but unfortunately, it only works for EnableRules, not DisplayRules. (See a very recent question for a similar problem.)
This function is typically used when a ribbon
<EnableRule>(RibbonDiffXml) depends on a value in the form. After your code changes a value that is used by a rule, use this method to force the ribbon to re-evaluate the data in the form so that the rule can be applied.
