          Date myfromDate;
          String[] tempStr = fromDate.split('/');
          Integer m = Integer.valueOf(tempStr[0]);
          Integer d = Integer.valueOf(tempStr[1]);
          Integer y = Integer.valueOf(tempStr[2]);
          myfromDate= Date.newInstance(y,m,d);
          
          Date mytoDate;
          String[] tempStr1 = toDate.split('/');
          Integer m1 = Integer.valueOf(tempStr1[0]);
          Integer d1 = Integer.valueOf(tempStr1[1]);
          Integer y1 = Integer.valueOf(tempStr1[2]);
          mytoDate = Date.newInstance(y1,m1,d1);

       listbadges=[select id,RecipientId,CreatedById,Definition.imageUrl,Definition.Description,CreatedDate from WorkBadge where RecipientId=:un and CreatedDate >=:myFromDate and CreatedDate <=:mytoDate];
     // system.assertEquals(listbadges,null);
       badges =new List<WorkBadge>();
       badges.addall(listbadges );
       badgeListSize = badges.size()>0? true:false;
       noBadgeMsg = badges.size()==0? true:false;
        return null;
