Answer 4

获得结果集DS后不要先填充Adapter, for循环取出每行数据比如：
          for(int i = 0; i<ds.table[0].rows.count;i++)
         {
           string address =ds.table[0].rows[0]["address"].tostring();
            if(address.length>20)
            {
               address = address.Substring(0, 20) + "...";
               ds.Tables[0].Rows[i]["address"] = address;
            }
         }
最后填充，然后绑定！
