I am not able to hide 'See All Records' button from UCI, the button is not available in Ribbon Workbench. Please refer below screenshot for better understanding - Is there any other alternative?
Currently I am working on MS Dynamics CRM online version 9.1. I have searched on internet but couldn't find something related to 'See all records' button on sub-grid. I have checked the forms for any setting while adding sub-grid, but no luck.
