我是做好界面，将sqldataadapter控件拖到窗体上，使用生成新的存储过程命令
分别是
bkSelectcomm
bkDeletecomm
bkUpdaetcomm
bkInsertcomm

具体在以下的程序中应该怎么用到？
下面我做的程序只可以添加新记录，但是却不能更改，说找不到update命令。
各位大哥，小弟初学C#，用的是VS2005，请帮帮我啊~

public partial class Book : Form
    {
        public Book()
        {
            InitializeComponent();
            sqlConnection1.Open();
            sqlDataAdapter1.Fill(bookDS1,"bkSelectcomm");
            CurrentPosition();
        }

        private void CurrentPosition()
        {
            int currentPostion, ctr;
            ctr = this.BindingContext[bookDS1, "bkSelectcomm"].Count;
            if (ctr == 0)
            {
                txtPosition.Text = "目前没有记录";
            }
            else
            {
                currentPostion = this.BindingContext[bookDS1, "bkSelectcomm"].Position + 1;
                txtPosition.Text = currentPostion.ToString() + "of" + ctr.ToString();
            }
        }

        private void btnExit_Click(object sender, EventArgs e)
        {
            this.Close();
        }

        private void btnBack_Click(object sender, EventArgs e)
        {
            try
            {
                btnBack.BindingContext[bookDS1, "bkSelectcomm"].Position -= 1;
                CurrentPosition();
            }

            }
            catch (System.Exception eRemove)

                System.Windows.Forms.MessageBox.Show(eRemove.ToString());
            }
        }

        }
    }

这个没有怎么留意，因为这次我没有把主键也放进dataset，它是自动增长的，可能造成无法更新。我再继续找一下错误，谢谢各位的提点了。
我一开始是将SQL2005里面一个表的所有字段都绑定到窗体的文本框中，但增加新记录的时候一直说ID作为主键已经存在有值了，不过我是将ID设成CHAR类型还是INT自动增长类型都不可以，所以就想着不绑定主键。结果可以添加新记录，但对以往记录就不能更改的。
是不是缺少了主键在dataset里面，所以就无法创建Update的存储过程呢？因为后面重新创建的时候好像只生成了两个存储过程，当时没有怎么留意。
