BindingSource绑定数据

Question

表 Student  属性 studentID name classID
表 Class    属性 ClassID className
我想在DataGridView中显示 StudentID name className
所以，将BindingSource绑定到Student_View (studentID, name, className)上，并将数据集保持在dataSet中
现在我要向Student表中插入新的数据
  public bool InsertSingleTableRecord(ref DataSet ds,string tableName,string tableKeyName,out string errMessage)
    {
        errMessage = "";
        return SqlHelper.InsertSingleTableRecord(ref ds, tableName, tableKeyName, ref errMessage);
    }
就会出现问题，该怎么解决？？？

Answer 1

的确这样做的
 DataSet ds = ((DataSet)this.bgSource.DataSource).Clone();
            //DataSet ds = new DataSet();
            string errMessage;
            DataRowView drv = (DataRowView)this.bgSource[this.bgSource.Position];
            DataRow dr = ds.Tables["Student"].NewRow();
            for (int i = 0; i < ds.Tables["Student"].Columns.Count; i++)
            {
                switch (ds.Tables["Student"].Columns[i].ColumnName)
                {
                    case "Name":
                        {
                            if ((drv[i] == DBNull.Value) || (drv[i].ToString() == ""))
                            {
                                MessageBox.Show("请输入名称!", "", MessageBoxButtons.OK, MessageBoxIcon.Information);
                                this.txtName.Focus();
                                return false;
                            }
                            break;
                        }
                    default:
                        break;
                }
                if (drv[i] == DBNull.Value)
                {
                    drv[i] = FdaGloble.SetDefaultValue(ds.Tables["Student"].Columns[i].DataType);
                }
                dr[i] = drv[i];
            }
            ds.Tables["Student"].Rows.Add(dr);现在的问题在于：BindingSource绑定的是试图，而我想操作的却是表
