NumericTextBox value is not a number in Angular












0















I have a strange problem with value in numericTextBox. I've got this error today:



ERROR Error: The NumericTextBox component requires value of type Number and {"value":null} was set.



In first sight, the problem is easy. But when I try to set a number value, problem still appears.



I try to get formControlName name from HTML in this way :



  <kendo-numerictextbox  [placeholder]="text" [spinners]="false"
[format]="" formControlName="first" required></kendo-numerictextbox>


takeIt= this.fobo.group({
first: [{ value: 3 }, [Validators.required, Validators.min(1), Validators.max(999999999)]]


fobo is injected in constructor from FormBuilder.
Where should I set a value? In HTML code or in ts code?



Thanks for your help!

          https://www.telerik.com/kendo-angular-ui/components/inputs/slider/forms/



          Note how the FormControl slider is instantiated



          public form = new FormGroup({
          slider: new FormControl(5, SliderValidator(5))
          })


          Your example is setting a default value in the first control of { value: 3}, that is a json string.... try instantiating your control like below and the value should be of type number.



          takeIt= this.fobo.group({
          first: [3, [Validators.required, Validators.min(1), Validators.max(999999999)]]
