Edit in grid view option will not be displayed for a particular view because of multitude of reasons. Some of the popular reasons were
- Adding Groupings
- Using supported browser
- Not having enough access on the list/library
Here is one more interesting addition to the above list. When a view is edited and set to have any different display Style other than ‘Default’ Edit in grid view option will not be displayed.
Microsoft may fix this limitation in future. As it stands today, if a view is set to have any other display Style other than default, Edit in grid view option will be unavailable.
Resolution: To get the Edit in grid view option back, set the display style back to Default.
