使用存储过程绑定gridview

Question

我有gridview,我在后端使用存储过程.问题是我没有使用任何文本框或仅标签gridview.

当我运行我的代码时,它显示一个编译错误,spproduct1期望参数@id,这是预期不提供的.你能解决这个错误吗？

public partial class WebForm1 : System.Web.UI.Page

{

  string _strsql = string.Empty;

  protected void Page_Load(object sender, EventArgs e)

  {

   string cs = ("Data Source=172.16.6.173;Initial Catalog=servion_hari;User  ID=sa;Password=Servion@123");

   _strsql = "select * from tblproduct where id=@id and Name=@Name and  Description=@Description";

    SqlConnection con = new SqlConnection(cs);

    con.Open();

    SqlDataAdapter da = new SqlDataAdapter("spgetproducts1", con);

    SqlCommand cmd = new SqlCommand();

    SqlParameter id = new SqlParameter("@id", SqlDbType.Int.ToString());

    id.Value = GridView1.ToString();


    da.SelectCommand.CommandType = CommandType.StoredProcedure;


     con.Close();

    DataSet ds = new DataSet();

    da.Fill(ds);

    GridView1.DataSource = ds;

     GridView1.DataBind();


        }
    }
}

对于存储过程方式:

        SqlConnection con = new SqlConnection(cs);
        SqlDataAdapter da = new SqlDataAdapter("spgetproducts1", con);
        da.SelectCommand.CommandType = CommandType.StoredProcedure;
        //first paramenter: parameter name, second parameter: parameter value of object type
        //using this way you can add more parameters
        da.SelectCommand.Parameters.AddWithValue("@id", GridView1.ToString());
        DataSet ds = new DataSet();
        da.Fill(ds);
        GridView1.DataSource = ds;
        GridView1.DataBind();

题; 你想用GridView1.ToString()实现什么？
