在MVC中获取多个嵌套的局部视图

Question

我有一页，其中包含一个多个部分页面。在每个局部视图中，将再次有多个局部页面。当我得到这个时，它将添加数据表到包含三个表的ds中。如何按层次结构显示它？

在我的ds中，来自数据库的三个表显示了特定的记录。我该如何显示？

这是我的DAL：

 public static ConsignmentNote GetConsignmentNoteByID(int id)
        {
            ConsignmentNote consignmentnote = null;
            SqlConnection sqlConnection = null;
            sqlConnection = SqlConnectionHelper.GetConnectionConnectionString();
            SqlCommand cmd = new SqlCommand();
            SqlDataAdapter da = new SqlDataAdapter();
            DataSet ds = new DataSet();
            try
            {
                cmd = new SqlCommand("GetConsignmentNoteByCNNoteId", sqlConnection);
                cmd.Parameters.Add(new SqlParameter("@ConsignmentNoteID", id));
                cmd.CommandType = CommandType.StoredProcedure;
                da.SelectCommand = cmd;
                da.Fill(ds);

                //First table data
                if (ds.Tables[0].Rows.Count > 0)
                {
                    DataRow row = ds.Tables[0].Rows[0];
                    consignmentnote = new ConsignmentNote(row);
                }
                else
                {
                    consignmentnote = new ConsignmentNote();
                }

                //Second table data 
                consignmentnote.LstAdditionalCN = new List<AdditionalCN>();
                int rowIndexCN = 1;

                if (ds.Tables[1].Rows.Count > 0)
                {
                    int i = 0;
                    foreach (DataRow acnRow in ds.Tables[i].Rows)
