Question

I am having a strange message displayed on the asp:label when trying to display data from a database. During page_load the asp:label is meant to be populated from a datasource however is displays the following message/text “System.Data.SqlClient.SqlDataReader”

What could be causing this?

I have written a small method in the page load of the .aspx.cs page.
labelName is the one which is displaying this message:

public partial class edit_questionnaire : System.Web.UI.Page
    {
        OsqarSQL GetData;

        protected void Page_Load(object sender, EventArgs e)
        {
            string questionnaireId = Session["qID"].ToString();
            int qid = Convert.ToInt32(questionnaireId);
            GetData = new OsqarSQL();
            string name = GetData.GetQuestionnaireName(qid);
            labelName.Text = name;

        }
    }

Which calls the following method:

public string GetQuestionnaireName(int questionnaireId)
        {
            string returnValue = string.Empty;
            SqlCommand myCommand = new SqlCommand("GetQuestionnaireName", _productConn);
            myCommand.CommandType = CommandType.StoredProcedure;
            myCommand.Parameters.Add(new SqlParameter("@QUEST_ID", SqlDbType.Int));
            myCommand.Parameters[0].Value = questionnaireId;
            SqlDataReader qName = getData(myCommand);
            while (qName.Read())
            {
               returnValue = qName.ToString();
            }
            _productConn.Close();
            return returnValue;
        }

And uses this stored procedure:

ALTER PROCEDURE [hgomez].[GetQuestionnaireName] 
    (
    @QUEST_ID int
    )   
AS
    /*SET NOCOUNT ON;*/
    SELECT QuestionnaireName FROM [Questionnaires] WHERE QuestionnaireID = @QUEST_ID
    RETURN

Answer 1

public string GetQuestionnaireName(int questionnaireId)
    {
        string returnValue = string.Empty;
        SqlCommand myCommand = new SqlCommand("GetQuestionnaireName", _productConn);
        myCommand.CommandType = CommandType.StoredProcedure;
        myCommand.Parameters.Add(new SqlParameter("@QUEST_ID", SqlDbType.Int));
        myCommand.Parameters[0].Value = questionnaireId;
        SqlDataReader qName = getData(myCommand);
        while (qName.Read())
        {
           returnValue = qName[0].ToString();
        }
        _productConn.Close();
        return returnValue;
    }

You were assigning the SqlDataReader to your returnValue rather than reading the value.
