protected void RadGrid1_ItemUpdated(object sender, GridUpdatedEventArgs e)
        {
            if (Label19.Text != null && Label18.Text != null)
            {
                System.Net.Mail.MailMessage msgMail = new System.Net.Mail.MailMessage();

                msgMail.Body = (" Dear  ") + "<br/>" + "<br/>" + (" Kindly Be Noted That There Is a New Request Has Been Add From : ") + Label19.Text + "<br/>" + "<br/>" + ("Kindly Check  ");

                msgMail.From = new MailAddress("");

                msgMail.To.Add(DropDownList5.SelectedItem.Attributes.ToString());

                msgMail.CC.Add("");

                msgMail.Subject = (" Your Request Had Been :  ") + Label18.Text;

                msgMail.IsBodyHtml = true;

                SmtpClient smtp = new SmtpClient("");

                smtp.UseDefaultCredentials = false;

                NetworkCredential crdntl = new NetworkCredential("");

                smtp.Credentials = crdntl;

                smtp.DeliveryMethod = SmtpDeliveryMethod.Network;

                smtp.Send(msgMail);

            }

Hello,

if (DropDownList5 != null)
        {
            if (DropDownList5.SelectedItem != null)
            {
                if (DropDownList5.SelectedItem.Attributes != null && DropDownList5.SelectedItem.Attributes.Count > 0)
                {
                    string str = Convert.ToString(DropDownList5.SelectedItem.Attributes);
                    // Access your attribute here
                }
                else
                {
                    // Attribute not found
                }
            }
            else
            {
                // Selected item not found. but some text in dropdownlist
                string str = DropDownList5.Text;
            }
        }
        else
        {
            // Dropdown not found
        }
