Question

Hi I have a stored procedure and a connection to the database. I have other similar code on my website that works just fine but for the life of me I cannot get this to work. I want the username of the person logged in to be passed as a parameter. I can get it stored in a session variable.
I wasnt sure how to transfer it from the session variable to the parameter so I put it into a label and sent it that way. It shows that it is getting that far but everytime I just get the message ‘nothing found’
I have checked the stored procedure and that seems fine to me. Below is the code and stored procedure! please help!

        using System;
        using System.Collections.Generic;
        using System.Linq;
        using System.Web;
        using System.Web.UI;
        using System.Web.UI.WebControls;
        using System.Web.Security;
        using System.Data.SqlClient;
        using System.Configuration;
        using System.Data;

        public partial class RescueOnlyPages_EditRescueDetails : System.Web.UI.Page
        {
            protected void page_PreInit(object sender, EventArgs e)
            {
                MembershipUser user;
                try
                {
                    if (User.Identity.IsAuthenticated)
                    {
                        // Set theme in preInit event
                        user = Membership.GetUser(User.Identity.Name);
                        Session["user"] = user;
                    }

                }
                catch (Exception ex)
                {
                    string msg = ex.Message;
                    //Log error here

                    // We have set theme in web.config to Neutral so if there is
                    // an error with setting themes, an incorrect theme wont be displayed to a customer

                }


            }
            protected void Page_Load(object sender, EventArgs e)
            {
                userLabel.Text = Session["user"].ToString();

                SqlDataReader myDataReader = default(SqlDataReader);

                SqlConnection MyConnection = new SqlConnection(ConfigurationManager.ConnectionStrings["RescueAnimalsIrelandConnectionString"].ConnectionString);

                SqlCommand command = new SqlCommand("sp_EditRescueDetails", MyConnection);    

                if (!User.Identity.IsAuthenticated)
                {
                }
                else 
                {
                    command.Parameters.AddWithValue("@user", userLabel.Text.Trim());

                }

                 try
               {
                MyConnection.Open();
                command.CommandType = CommandType.StoredProcedure;

                myDataReader = command.ExecuteReader(CommandBehavior.CloseConnection);
                myDataReader.Read();


                GridViewED.DataSource = myDataReader;
                GridViewED.DataBind();

                if (GridViewED.Rows.Count >= 1)
                {

                    GridViewED.Visible = true;
                    lblMsg.Visible = false;           

                }
                else if (GridViewED.Rows.Count < 1)
                {
                    GridViewED.Visible = false;

                    lblMsg.Text = "Your search criteria returned no results.";
                    lblMsg.Visible = true;
                }





                MyConnection.Close();
               }
                 catch (SqlException SQLexc)
                 {
                     Response.Write("Read Failed : " + SQLexc.ToString());
                 }
            }


            }

stored procedure

 ALTER PROC [dbo].[sp_EditRescueDetails]
(
   @user nvarchar(50)

 )
 AS
 BEGIN


 SELECT [PostalAddress], [Telephone_No], [Website], [Email] 
 FROM [RescueDetails] 
 Where   [UserName] = @user 
 End

EDIT *
If I change the stored procedure and delete the
‘ Where [UserName] = @user ‘
line it brings in every user detail without any problem so I think it maybe something with this line or the
command.Parameters.AddWithValue(“@user”, userLabel.Text.Trim());
line that is causing me the problems

Answer 1

Try setting

command.CommandType = CommandType.StoredProcedure;

before

 MyConnection.Open();

Also don’t call myDataReader.Read(); if you are going to set the myDataReader as the data source for gridview. That will make it skip a row and if result has only one row then the grid will display nothing.
