Hi All,

I would like to know , how will below mentioned alert will trigger when page is not saved and moving on to another page

This alert is coming from "Form" widget( out of box ).

Could any one help me out on this.

Hi Rajashekar,

I think this message comes in form as well whenever you change something and are about to leave the page

so it must be coming from platform level and as a developer you may not have access to it

Mark Correct if this solves your issue and also mark Helpful if you find my response worthy based on the impact.
Thanks

Hi Ankur,

Thank you for your response.

 It will happen in service portal as well, ie Form and catalog widgets.

I would like to know , how it calls from "form" widget.

as shown in the screen shot.

As Ankur has said, this can't be configured / customised.

It is very much in line with standard web browser form behavior.

The browser checks if there is any data in a form and throws a warning if you try to navigate away without submitting.
