can you say like this....

protected void Page_Load(object sender, EventArgs e)
{
if (Page.IsPostBack == false)
{
SqlConnection objConn = new SqlConnection(ConfigurationManager.ConnectionStrings["BuildMyPCConnectionString"].ToString());
objConn.Open();

SqlCommand objCmd = objConn.CreateCommand();
objCmd.CommandType = CommandType.StoredProcedure;
objCmd.CommandText = "PR_ProductID_SelectByPK";
objCmd.Parameters.AddWithValue("@ProductID", Convert.ToInt32(Request.QueryString["ProductID"]));

SqlDataReader objSdr = objCmd.ExecuteReader();

dlProductDetail.DataSource = objSdr;
dlProductDetail.DataBind();

SqlCommand objCommand = objConn.CreateCommand();
objCommand.CommandType = CommandType.StoredProcedure;
objCommand.CommandText = "PR_ProductSpec_SelectByPK";
objCommand.Parameters.AddWithValue("@ProductID", Convert.ToInt32(Request.QueryString["ProductID"]));
SqlDataReader objSqldr = objCmd.ExecuteReader();
GridView1.DataSource = objSqldr;
dlProductDetail.DataSource = objSqldr;
GridView1.DataBind();

}

}
this is not work error occur
There is already an open DataReader associated with this Command which must be closed first.

in above pgm for 2nd procedure you used objCmd.ExecuteReader(); its wrong use objCommand.ExecuteReader(); if then also problem persist then close old connection and open new one.

vinayraghavendra.hs 28-Mar-13 8:15am

you don need to bind data to datalist in 2nd procedure pgm early binding is enough.

Try below..

C#

protected void Page_Load(object sender, EventArgs e)
    {
        if (Page.IsPostBack == false)
        {
             //for datalist
            SqlConnection objConn = new SqlConnection(ConfigurationManager.ConnectionStrings["BuildMyPCConnectionString"].ToString());
            objConn.Open();
 
            SqlCommand objCmd = objConn.CreateCommand();
            objCmd.CommandType = CommandType.StoredProcedure;
            objCmd.CommandText = "PR_ProductDetail_SelectByPK";
            objCmd.Parameters.AddWithValue("@ProductID", Convert.ToInt32(Request.QueryString["ProductID"]));
 
            SqlDataReader objSdr = objCmd.ExecuteReader();
            dlProductDetail.DataSource = objSdr;
            dlProductDetail.DataBind();
            
            //for gridview
            SqlCommand objCmd1 = objConn.CreateCommand();
            objCmd1.CommandType = CommandType.StoredProcedure;
            objCmd1.CommandText = "PR_ProductDetail_SelectByPK_Gridview";
            objCmd1.Parameters.AddWithValue("@ProductID", Convert.ToInt32(Request.QueryString["ProductID"]));
 
            SqlDataReader objSdr1 = objCmd1.ExecuteReader();
            Gridview1.DataSource = objSdr1;
            Gridview1.DataBind();
            
            con.Close();

        }
    }
