How to automatically open the home page of my HMI after entering credentials in mappview?

Hi @zabalale7! I agree on @kovarj that the way to create a dialog and just close it after successful log in is a “cleaner” way to implement what you want. You can check here how to create a dialog box: B&R Online Help - Dialog boxes

I also attach an image of how to implement the event-action structure to navigate to home screen or to close the dialog after triggering the event of LoginSuccess.
