In my Employee Class, property EmpName cannot be blank.

In the ServerModelDesigner, the StringLengthVerifier is added with IsRequired set to true, due to which the devforce's default validation message "EmpName is required" gets displayed when we call the VerifierEngine.Execute(...) function.
 
We have partial class of Employee where we create verifiers related to Employee.
We need to override the StringLengthVerifier created in the ServerModelDesigner and show our custom message as to "Employee Name is required" instead of "EmpName is required".
 
So when we call the VerifierEngine.Execute(...)  function, it should return only one VerifierResult "Employee Name is required"
 
Can any one please respond with a solution?

pchavan:

You can set up a PropertyNameToDisplayNameTranslator delegate to make verifiers use the display name instead of the property name in their messages, as follows:

_entityManager.VerifierEngine.PropertyNameToDisplayNameTranslator =

  delegate(Type pType, String pPropertyName) {

    var attr = ReflectionFns.GetAttribute<DisplayAttribute>(pType.GetProperty(pPropertyName));

return attr.Name;

};

 
Then just set the Display Names for your properties, as desired, in the Object Mapper -- e.g., set the Display Name for the EmpName property to "Employee Name" -- and the verifier will use that name in the message.
