`namespace VirtualPremise.Domain.Financials.BLL
{
    [Serializable()]
    public class GLGroupEvent : GLEventInfo
    {
        public int GLEventGroupID { get; set; }

        public string GroupName { get; set; }

        public decimal ChangeInIndex { get; set; }

        public static GLGroupEvent GetGLGroupEvent(int glEventID, string sitekey)
        {
            try
            {
                GLEventInfo eventInfo;
                eventInfo = BLL.GLEventInfo.GetGLEvent(glEventID, sitekey);
                var grpEvent = eventInfo.Adapt<GLGroupEvent>();
                return grpEvent;
            }
            catch (Exception ex)
            {
                throw;
            }
