I received an requirement from my boss to display more than the default 6 rows in the Edit in Datasheet view of data lists. I hate this beast (ie. datasheet) because it is really unpredictable (see my previous posting).
After messing around I found the simplest solution was to alter the OOB core.js:
Changed:
cGCMinimumHeight=200;
to:
cGCMinimumHeight=600;
This offcourse makes the change global for all Datasheets and very exposed to future updates from Microsoft. So add it to your list of things to check after next upgrade…
