I tried using display rule and enable rule to show/hide the delete button in the subgrid, but it's not working. I am only able to do it for the add new button. I think it has to do with the delete button not being displayed, as I have to click on the three dots to show the delete button. Where as the add new can be seen as soon as the subgrid is in view. Very frustrating....I want to show/hide based on a field value from the main form.
