Asp.net mvc: automatically generating validation!

Question

Here is the class code check there is no DataAnnotation.

 public int Rotate { get; set; }

Here is the its use

@Html.HiddenFor(model => model.Screen.Rotate)

Here its generating html, y its generating validation rules????

<input type="hidden" value="" name="Screen.Rotate" id="Screen_Rotate" data-val-required="The Rotate field is required." data-val-number="The field Rotate must be a number." data-val="true">

Note: If i change int Rotate to string Rotate then it does not generate extra attributes for validations like data-val-required, data-val-number etc.

Are you sure? Yes, you'll get the number validation, but you should not be getting required with `int?` . Your problem may be elsewhere. — Craig Stuntz, Feb 07 '11 at 17:10

Non-nullable scalar values such as int and DateTime are always considered as required. string isn't required since strings are nullable. As @Biff said, use int? for a non-required int.
