IDataErrorInfo interface implementation

[RadKrish]

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); }
        }
        #endregion
}

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??
