c# - Arranging in order with reference to a column -

i have mysql database table ( using entity framework ) :

here codes use retrieve , populate them on wpf : crud class file :

        //get records based on activityid , taskid.     public ilist<model.questionhint> getrecords(int listtask, int listactivity)     {         ilist<model.questionhint> lstrecords = context.questionhints.tolist();         return lstrecords.where(a => a.taskid == listtask && a.activityid == listactivity).tolist();       } 

code behind :

      public mainwindow2()     {         initializecomponent();         populatequestion(1, 5);     }      private void populatequestion(int activityid, int taskid)     {         ilist<model.questionhint> lstquestionhints = qh.getrecords(taskid, activityid);          foreach(model.questionhint qhm in lstquestionhints)         {              textblock tb = new textblock();             tb.text = qhm.questioncontent;                           tb.fontweight = fontweights.bold;             tb.fontsize = 24;             wrappaneltest.children.add(lbl);              if (qhm.option1.trim().length > 0 &&                 qhm.option2.trim().length > 0)             {                 combobox cb = new combobox();                 cb.items.add(qhm.option1);                 cb.items.add(qhm.option2);                 cb.width = 200;                 wrappaneltest.children.add(cb);             }          }     } 

how appear on program :

as can see , questions compounded , want separate them based on questionno in above database table ( example few records same questionno should compound together.)but got totally no idea how . want separate them :

i [combobox] have nap every afternoon.

the sun [combobox] not move round earth.

appreciate on , in advance.

try this

     stackpanel sp=new stackpanel();     foreach(model.questionhint qhm in lstquestionhints)     {     stackpanel sp1=new stackpanel(){orientation=orientation.horizontal};              textblock tb = new textblock();         tb.text = qhm.questioncontent;                       tb.fontweight = fontweights.bold;         tb.fontsize = 24;         sp1.children.add(lbl);          if (qhm.option1.trim().length > 0 &&             qhm.option2.trim().length > 0)         {             combobox cb = new combobox();             cb.items.add(qhm.option1);             cb.items.add(qhm.option2);             cb.width = 200;             sp1.children.add(cb);         }        sp.children.add(sp1);      }     wrappaneltest.children.add(sp);
