I have approximately 1300 fields. There are several (into the hundreds) that for visual purposes only need to share the same alternate text label. Is there an easy way to change the alternate text label for many fields at once?
If you have a record with 1300 fields, I suggest that perhaps your record has too many fields and the design of your app should be reviewed. perhaps those fields can be child records of a parent table. This setup is likely to lead to problems down the road.
