ANGULAR 15 : CREATE DYNAMIC CONTROLS IN REACTIVE FORMS

In this tutorial, we will see how to add the form controls in the html at runtime using formarray in reactive forms in Angular 10.
Here we will just take an example of the Mobile numbers in form.
When the user clicks on add new mobile button, the new mobile input textboxes will be generated at runtime. The user can then enter there alternative mobile numbers.
We will also see how to fetch those values from the runtime generated textboxes.
Example of FormArray in Reactive from :
userprofileForm = this.fb.group({
firstName: ['', Validators.required],
lastName: [''],
address: this.fb.group({
address1: [''],
address2: [''],
state: [''],
zip: ['']
}),
mobiles: this.fb.array([
this.fb.control('')
])
});
Here mobiles is the formarray.
We will now see how to add the formcontrols in this formarray at runtime and display those controls in Html.
Also we will see how to fetch the values from those runtime controls.

[@krishnayallapanthula]

why are you using push instead of insert to add mobile number dynamically?

[@kolluruprakash]

Hi. For this generating dynamic controls same trying to implementin on my local machine. But, in console throwing error like : "Property 'push' does not exist on type '() => FormArray' ". Please, make me come out from this issue. respond ASAP. Thanks for your wonderful explanatory videos.

}

[@pcoderajap2913]

[@adarshsocialgroup8097]

here you used only mobile number . what if we have multiple text fields at one click . how can we assign formControlName to all bunch of fields once. please provide syntax

[@gopikrishnalifestyle]

Can you create an example of this by taking year and month displaying dates with text boxes?

[@ferdysduran9173]

Thank you, but I have a problem, how can I show the data when it comes from an API? To make it clear when I have already saved the data and now I want to edit it, then I need to show the saved data to edit

[@sravaniperumalla3377]

Can you please make some Model driven Forms video, which will take an object and auto populate the form by that object properties

[@azadeh2486]

[@marcusdutton933]

I'm new to angular development do you have some examples of getting all form values from formArray be able to push that to a service for CRUD operations.

[@ashutoshpatra440]

[@ashutoshpatra440]

@techie ocean please help me....i am new to angular

[@sakthieswar9670]

In this tutorial you have added one text box only, if i want to add multiple text boxes like mobile number + address + email etc, how I can achieve this ?

[@tiredoftheliesalready]

Welcome to the problem of every tutorial you will find on this topic; basic non-use-cases that do not explain enough, and/or do not show you anything real-world. I've just about given up; I can do this is straight JS / TS or in React without as much nonsense and time wasted trying to find any decent explanation (because Angular's documentation is absolute garbage). I've never seen such a shoddily documented framework, for all the money and popularity Angular has.

[@Aadishiva1]

how we can do it if we have component not static HTML
