    Hello, I would like to achieve the red validation pop-out message as shown in the 2nd picture from the link above. All my other codes are working, except for red pop-out message. Is there anything I'm overlooking? Below are my codes:

    private void GridCommsEqp_OnCellValidating(object sender, GridViewCellValidatingEventArgs e)
            {
                switch (e.Cell.Column.UniqueName)
                {
                    case "SSN":
                        if (e.NewValue.ToString().Length > 30)
                        {
                            e.IsValid = false;
                            e.ErrorMessage = string.Format("{0} must not be longer than 30 characters. " +
                                                           "Current length: {1}", e.Cell.Column.Header,
                                                           e.NewValue.ToString().Length);
                        }
                        break;
                    case "OfficialDesc":
                    case "CommonDesc":
            .
            .
            .
            }

    Hi Dexter,

    I have prepared a sample project based on the provided code snippet and everything seems to work as expected. May I ask you to modify the attached project in order to reproduce the issue? Then you can send it back to me for further investigation.
