I am working on MScrm 365 on-premise there is a new feature pop out this form after clicking this button the form is out but the page is refreshed to a grid, is there an option to disable this refresh?
Unfortunately this is by product design, once you pop-out the record, the user navigate away to the grid/list page in main window.
You can implement a custom button logic and implement your need instead of rigging the product behavior which is unsupported and will break in future releases.
