            }

Check out the password length validation in ChangePasswordPanel.ts.

You say it is a number though, so maybe try add the IntegerEditor option to this field in your xyzRow.cs like so:

[IntegerEditor(MinValue = 1000000000)]
[DisplayName("National ID"), Size(10), NotNull, QuickSearch]
public Int64? NationalID
{
    get { return Fields.NationalID[this]; }
    set { Fields.NationalID[this] = value; }
}

And if you change your validation rule to check the length of the value, and not the element (like in the password length validator)?

this.form.Username.addValidationRule(this.uniqueName, x => {
// Your example is using this.form.Username.element.length
var nationalID = this.form.Username.value.length;

            if (nationalID !=10) {
                return "National ID is too short"
            }
        })

toString is a function and needs the brackets to be evaluated...

Check these outputs:

this.form.Username.change(x => {
    console.log("Not working");
    console.log("this.form.Username.value.toString.length");
    console.log(this.form.Username.value.toString.length);
    console.log("Working");
    console.log("this.form.Username.value.toString().length");
    console.log(this.form.Username.value.toString().length);
    console.log("this.form.Username.value.length");
    console.log(this.form.Username.value.length);
})
