Hi!
I have a Db table. what i want is to get data using group by clause as i have used in below code.
Note that Decision is another table. now i want that all the decisions related to a specific Meeting Title should be shown in list.like
meetingtitle1=decision1,decison2,decison3
meetingtitle2=decision1,decison2
but below code returns only one decisiontitle.

C#

public List<NewMeetings> GetAllMeetings()
       {

           var xyz = (from m in DB.MeetingAgenda
                      //join mp in Meeting on m.MeetingId equals mp.MeetingId
                      //where m.MeetingId == 2
                      group m by new { m.Meeting.MeetingTitle } into grp
                      select new NewMeetings
                      {
                          //  meetingid = grp.Key.MeetingId,
                          meetingtitle = grp.Key.MeetingTitle,
                          decision = grp.Select(x => x.Decision.DecisionTitle).FirstOrDefault(),

                          total = grp.Count()
                      }).ToList();

           List<NewMeetings> list = xyz.ToList();
           return list;
         

          
       }

       public class NewMeetings
       {
           public int meetingid;
           public string meetingtitle;
           public string decision;
           public int total;
       }

You can include the Decision table in the select of the MeetingAgenda

C#

var queryResult = from meeting in DB.MeetingAgenda.Include(d => d.Decisions)
                  where (meeting.x == ??)
                  select meeting

You need to include the System.Data.Entity namespace for the code above.

If you loop through the queryResult, each meeting will have a collection of decision objects present.
