Angular 5+ Reactive Forms [Nested]

Submit is not a directive, it's an event

This is good example, but If we have another nested loop with form array. how we can handle with validation, please let us knows. I have pasted json. {"employee": [{"name": "abc","records": [{ "department": "software","salary": "12000"},{"department": "UI","salary": "15000"}]}]}

Neither
let brand of productsForm['controls'].brands['controls']
Nor
let brand of productsForm.controls.brands.controls
are working.. Can somebody help?

Sir how to validate nested form

how can i add new Form control inside nested group? I can use addControl for main formGroup but i dont have addControl method for nested group????????

Thank you so much this really help me alot.

This is NOT a nested form. This is a simple form array. A nested form is where the nested form is in a different component.

You are a genius man, you dont realize how much do you help me with this video. A huge hug from Argentina (seriusly, you save me a several hours of study and work )

If the user makes change to the input box in the second row and wants to revert changes for that row, How to figure out the previous (initial) value of the input box of that row?

Nicely done. This is helpful. A few things I would say are first that I try not to use FormBuilder. I think building the form using "new" and FormControl, FormGroup and FormArray is a better approach. Second, I am not sure that iterating over a FormArray in the html is really the same as a "nested" reactive form. Am I right that in the end you still have ONE form? You do not have forms within forms. Perhaps I am over-thinking it.

Thanks for this tutorial!
One thing I would like to mention, following your example, i get error: "ERROR in src/app/app.component.html(8,21): : Property 'controls' does not exist on type 'AbstractControl'."
Here is the fix: "let brand of productsForm['controls'].brands['controls']" instead of "let brand of productsForm.controls.brands.controls;"

I use this but give error " value of null" so if possible please solve it

Thankyou Very Much Brother ,it helped me alot God bless U
