asp.net core docker Angular value vs ngvalue

In this video we will discuss how to validate a select element if it has a custom option like "Please Select" etc. Along the way we also discuss the difference between value and ngValue in Angular.

If you use value, null is treated as a string and not as a null. Hence the required validation does not work.

If you just want the selected value as a string then use value property.

If you want the selected object from the SELECT element, then use ngValue.

Use the disabled attribute, if you do not want the user to be able to select the first default option.

The built-in required validator will only work with the SELECT element, if the default option value is null.
