  Dear All,
  I have created a project using EF4, RIA Service, few telerik controls.
  
  I define my client-side validation using .shared files and add then using DataAnotation to the metadata class as follows:
  

  public static class CustomDailyValidation

  {

      public static ValidationResult ValidateSubsidiary(int id, ValidationContext validationContext)

      {

          if (id <= 0 || id == null)

          {

              return new ValidationResult("ERROR", new[] {validationContext.DisplayName});

          }

          return ValidationResult.Success;

      }

  }

  
  MetaData:
  

  [CustomValidation(typeof(CustomDailyValidation), "ValidateSubsidiary")]

  public int subsidiary_id { get; set; }

  
  I then populate the subsidary_id with data using QDSCV (no Problem here)
  
  I then add the xaml definition as follows:
  

  <telerik:RadComboBox x:Name="discriptorId" Margin="0,0,0,5" Grid.Row="1" Grid.Column="3" IsEnabled="{Binding IsNew}"

      ItemsSource="{Binding Path=DiscriptorsCollection,Mode=TwoWay}"

      SelectedValue="{Binding Path=CurrentDaily.discriptor, Mode=TwoWay,NotifyOnValidationError=True,ValidatesOnExceptions=True}"

      SelectedValuePath="discriptor_id"

      DisplayMemberPath="discriptor_name_1"/>

  
  The validation works as soon as I open the page, I don't know why, but anyway that is not the problem, the problem is that the subsidary_id combobox is displaying the error but with different message says "Input is not in correct format".
  
  I don't know from where is that comes? how to stop / override?
  
  Note:
  I have another RadDatePicker that has different validation method,
  when I set a break point in the client-side validation class the validation method for the date field is hit, but not the combo.
  
  Any help !!
