Question

I am having trouble returning data from my sql-server database to an aspx page using a stored procedure and was hoping somebody could highlight where I am going wrong.

When I run the project data is successfully input into the table but nothing is returned on the following page (Confirm.aspx)

Confirm.aspx.cs

using Devworks;

namespace OSQARv0._1
{
    public partial class Confirm_Questionnaire : System.Web.UI.Page
    {
        OscarSQL b;

        protected void Page_Load(object sender, EventArgs e)
        {
            b = new OscarSQL();
            string qstname = b.GetQuestionName();
            ReturnQstID.Text = qstname;          

        }// End Page_Load

    } // Emd Class Confirm_Questionnaire

} // End Namespace

SQL.cs (App Code)

public OscarSQL()
        {
            _productConn = new SqlConnection();
            _productConnectionString += "data source=mssql.database.co.uk; Initial Catalog=devworks_oscar;User ID=username;Password=password";
            _productConn.ConnectionString = _productConnectionString;
        }
    public string GetQuestionName()
            {
                SqlCommand myCommand = new SqlCommand("GetQuestion", _productConn);
                myCommand.CommandType = CommandType.StoredProcedure;
                SqlParameter retval = myCommand.Parameters.Add("@QUESTTEXT", SqlDbType.VarChar);
                retval.Direction = ParameterDirection.Output;
                _productConn.Open();
                string returnvalue = (string)myCommand.Parameters["@QUESTTEXT"].Value;
                _productConn.Close();
                return returnvalue;
            }

Stored Procedure

USE [devworks_oscar]
GO

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

ALTER PROCEDURE [hgomez].[GetQuestion]  

AS
    /*SET NOCOUNT ON;*/
    SELECT QuestionText FROM [Questions] WHERE QuestionnaireID = 21
    RETURN

Any help would be much appreciated.

You aren’t executing the proc. You are setting it up, but not returning it.

string returnvalue = (string)myCommand.ExecuteScalar();
