Stepper should provide an click event for step changes

[gobi004]

Bug, feature request, or proposal:
Feature request

What is the expected behavior?
Add an click event that gets triggered when the step is clicked in the stepper component

What is the current behavior?
There's no such event.

What are the steps to reproduce?
NA

What is the use-case or motivation for changing an existing behavior?
We have some business logic that we need to save at each step. We have to show the message on click of step "Are you confirm?", we implemented with button click but unable to do in step click, and it's moving forward to next step on clicking of step.

Which versions of Angular, Material, OS, TypeScript, browsers are affected?
Angular 9+
Angular material 11.2

Is there anything else we should know?
Tried to use selectionChange event, no use.its working after the click event. i want to show or prevent before the change event.

<mat-horizontal-stepper (selectionChange)="selectionChange($event)">
<mat-step (click)="alert()">

needs to add click event on step like above. As of there is no option like that

I don't quite follow what the issue with selectionChange is here. Is it that you want to prevent the user from moving based on a specific condition?

[gobi004]

similarly but click on each step api is calling based on the data availability only it should move to next step.And which can be done in 'next' button but on click of step icon or number its moving to second step before api is get fetched.

i want to add custom click for each step not in .

@gobi004
You can achieve the same by setting disabled property on button
Or do not use CdkStepperNext and implement your own (click) handler , where you call this.next() for your stepper component

@abdulkareemnalband with this method, you wont have access to previousIndex. Also you cannot assign click handler to whole mat-step because it is not available after DOM.

Thank you for submitting your feature request! Looks like during the polling process it didn't collect a sufficient number of votes to move to the next stage.

We want to keep Angular rich and ergonomic and at the same time be mindful about its scope and learning journey. If you think your request could live outside Angular's scope, we'd encourage you to collaborate with the community on publishing it as an open source package.
