    IDataErrorInfo interface implementation

    Hello All
    I am trying to implement MVVM and use IDataErrorInfo interface to validate data in the model classes

    I base model class implementing IDataErrorInfo interface

    public class BaseClass: IDataErrorInfo
       <Properties and Members of BaseClass>
            #region IDataErrorInfo
            public string Error
                get { return String.Empty; }
            public string this[string PropertyName]
                get { return this.GetValidationError(PropertyName); }
    Now I want drive a class from Base class

    public class DrivedClass: BaseClass
    How do I use IDataErrorInfo members in the derived class to carryout validation of the properties in the derived class??
