Even though i have set the minlength to 5 it only gives me an error when the length is 0.

here is a plunker i have made that demonstrates that:

This is how i set the validation:

  formGroup.sensitivity = 
   this.formBuilder.control(this.reportModel.sensitivity, [Validators.required, 
   Validators.minLength(5)]);

Answer 1

For numbers, you should use Validators.min() instead of minLength() if you want to check for a number that must be minimum 5. minLength() is used for the number of characters in a text.

formGroup.sensitivity = 
   this.formBuilder.control(this.reportModel.sensitivity, [Validators.required, 
   Validators.min(5)]);
