We need to have a grid with editable cells without clicking or hover options (ie) the grid cells should be editable at all the time. Attaching screenshot for reference.
After testing, we found that the Advanced Grid appears to function as desired. This is a legacy widget which will be removed at some point in the future, but you can continue to use it in the meantime. I also recommend that you submit a request on the ThingWorx Ideas forum to request that the new Grid functionality be updated to match that of the Grid Advanced.
