จาก Code และภาค มีวิธีทำให้มันเป็นรูปแบบ dd-MM-yyyy ไหมครับ ผมลองเปลี่ยนดูแล้วทำไม่ได้ C# Code ทดสอบ ตามภาพแล้วทำไม่ได้ ต้องทำยังไงมีวิธีแนะนำผมหน่อยครับ

string.Format("{0:dd-MMM-yyyy HH:mm}", Convert.ToDateTime(sDate));

       public static string DisplayDateTime(object sDate)
        {
            try
            {

                if (sDate == System.DBNull.Value || sDate == null || sDate.ToString() == string.Empty)
                {
                    return string.Empty;
                }
                else
                {
                    return string.Format("{0:dd-MMM-yyyy HH:mm}", Convert.ToDateTime(sDate));
                }

            }
            catch (Exception ex)
            {
                return sDate.ToString();
            }

        }
