Retrieving Form Data and Reseting Form | Angular Forms | Angular 13+
We are almost done with template driven form in Angular. The only thing which is left to learn is how to retrieve the form data from a template driven form and how to reset a form.
That's what we are going to learn in this lecture. The NgForm object has a value property which contains all the form control as its property and the value entered for those form controls as the value for thos properties.
So, to read the value entered in the form controls of a template driven form, we need to access the value property on NgForm and on that we can access the required property values.
We can also reset the form controls to their initial value and state using reset() method of NgForm. Let's learn these concepts with an example in this lecture.

the problem is that the 'set default values' button is working as a 'submit' button, to solve this you need to specify the type of the 'set' button to: type="button" Set Default Values

Hello Sir, in the previous lecture- we used this.form.value.personDetails.firstname to set the values and it did not work. So we used this.form.setValue and set them there. But in this lecture we are using - this.form.value.personDetails.firstname is used to retreive the values. Could you please clarify ?

Yes, we can retrieve the value of firstName field from value object using this.value.personDetails.firstName. But we cannot set the property values of value object in that way. So to set the value, we have to use setValue method. Explaining the reason is not possible in comment, so i will create a lecture on the same. For now i will say, that we need to use setValue or patchValue because we want to persist the data even when the form is submitted.
