How to log message in 'messageTemplate' field in validation section of web.config

Question

Hi,

I am using Enterprise Library 5.0 and trying to use Validation block. In case of validation fails the log message displayed is something like bellow message:

" Message : Parameter validation failed "

I want to log message in 'message template' field in web.config file.

Please assist me.

Bellow is given 'validation' section in web.config

<validation>
    <type name="MusicStore.Classical" defaultRuleset="Classical RuleSet"
      assemblyName="MusicStore, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null">
      <ruleset name="Classical RuleSet">
        <properties>
          <property name="Name">
            <validator type="Microsoft.Practices.EnterpriseLibrary.Validation.Validators.NotNullValidator, Microsoft.Practices.EnterpriseLibrary.Validation, Version=5.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
messageTemplate="Album Name can not be empty"
              name="Not Null Validator" />
            <validator type="Microsoft.Practices.EnterpriseLibrary.Validation.Validators.StringLengthValidator, Microsoft.Practices.EnterpriseLibrary.Validation, Version=5.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
              upperBound="20" lowerBound="10" lowerBoundType="Inclusive" upperBoundType="Ignore"
messageTemplate="Album name should be at least one character long"
              name="String Length Validator" />
          </property>
        </properties>
      </ruleset>
    </type>
  </validation>

Thanks to all, I got the solution,

In case we using Policy injection and used validation call handler for a perticular member type matching rule, then if validation fails, It will throw an exception of type 'ArgumentValidationException' which contain a property (ValidationResults) coantaining collection of validation results

So in catch block we can iterate through validation results and get the value in message template field as given bellow:

catch (ArgumentValidationException ex)
            {
                ValidationResults results = ex.ValidationResults;
                foreach (var item in results)
                {
                    Console.WriteLine(item.Message);
                }

              
                Console.Read();

            }
