Model require in mvc

Anonymous User 1888 10-Oct-2014
Is there a way through data annotations to require that a boolean property be set to true?
public class MyAwesomeObj
{
    public bool ThisMustBeTrue { get; set; }
}

You could create your own validator:
public class IsTrueAttribute : ValidationAttribute
        {
            #region Overrides of ValidationAttribute
            public override bool IsValid(object value)
            {
                if (value == null) return false;
                if (value.GetType() != typeof(bool)) throw new InvalidOperationException("can only be used on
boolean properties.");
 
                return (bool)value == true;
            }
 
            #endregion
        }
