Model require in mvc

Anonymous User167410-Oct-2014
Is there a way through data annotations to require that a boolean property be set to true?
publicclassMyAwesomeObj
{
    publicbool ThisMustBeTrue { get; set; }
}

You could create your own validator:
publicclassIsTrueAttribute : ValidationAttribute
        {
            #region Overrides of ValidationAttribute
            publicoverridebool IsValid(object value)
            {
                if (value == null) returnfalse;
                if (value.GetType() != typeof(bool)) thrownewInvalidOperationException("can only be used on boolean properties.");
 
                return (bool)value == true;
            }
 
            #endregion
        }
