Answer 1

If you are using forms, you can implement that by

this.formName.formControlName.setValue(valueYouWantToSet);

for this to work, you will have to get the controls of the form via:

get f() { return this.formName.controls }

If you are not using forms and want to implement via ngModel([(ngModel)]="variableName"), then you can try with

this.variableName = valueYouWantToSet
