very simple solution adding default item works only for observationcollection and list. see the code. or code behind : List lst = o.Entities.ToList (); DistrictComplexClass _objlist = new DistrictComplexClass(); _objlist.DistrictId = 0; _objlist.DistrictNameMar = Select; lst.Insert(0 _objlist); cmbDistrictLevel.ItemsSource = lst; cmbDistrictLevel.DisplayMemberPath = DistrictNameMar; cmbDistrictLevel.SelectedValuePath = DistrictId; cmbDistrictLevel.SelectedIndex = 0;
