DataGrid 查出一个列 按要求显示格式 例如:操作人(地点)
这是转换DataGrid显示格式之后 连接字符串的方法 显示:操作人(地点)
public static ObservableCollection<CListModel> AllUserList { get { if (_AllUserList == null) { _AllUserList = new ObservableCollection<CListModel>(); var users = UserDal.GetInstance().GetUserByCondition(new XGX_USER()); foreach (var item in users) { StringBuilder sb = new StringBuilder(); sb.Append(item.USER_NAME); if (!string.IsNullOrEmpty(item.USER_PLACE)) { sb.Append("("); sb.Append(item.USER_PLACE); sb.Append(")"); } _AllUserList.Add(new CListModel() { DisplayValue = sb.ToString(), SelectValue = item.USER_ID }); } } return _AllUserList; } }
另一种简单的方法:
public const string SQL_SELECT_XGX_BALANCE = @" SELECT T.ID, T.SUM, T.OPERATOR, (U.USER_NAME || '('||U.USER_PLACE||')') OPERATOR_N, //操作人(地点) T.OPERATION_TIME, T.STATUS FROM XGX_BALANCE T LEFT JOIN XGX_USER U ON T.OPERATOR=U.USER_ID ";
左联 USER表 查出
(U.USER_NAME || '('||U.USER_PLACE||')')
XAML Binding OPERATOR_N
