CustomValidation and ErrorMessage

[Louis Bouchard]

Hello,

In my metadata.cs file I use a CustomValidation like this :
...
[CustomValidation(typeof(MesValidations), "DescriptionActionPreventiveUneValeur")]
public string DescriptionActionPreventive_en { get; set; }
...

But when my ErrorMessage is displayed, it's in tooltip not within a red rectangle (see attachement). 

MesValidations.shared.cs :

public static System.ComponentModel.DataAnnotations.ValidationResult DescriptionActionPreventiveUneValeur(Object DescriptionActionPreventive, ValidationContext context)
{
    if (((String)DescriptionActionPreventive) == "oui")
    {
        return System.ComponentModel.DataAnnotations.ValidationResult.Success;
    }
    else
    {
        return new System.ComponentModel.DataAnnotations.ValidationResult("I'm not in the red rectangle error message!");
    }
}

I want know if it's related with my code or someting wrong with my RadGridView.

Thank you
