SqlDataReader Read method not working

Question

I am trying to retrieve column values from database here is my code

protected void LoadProfile()
{
        conn = new SqlConnection(connString);

        cmdProfile = new SqlCommand("SELECT Name, Father, Gender, UserName, City, Country, Department, Year, Degree, JobTittle, Organization, JobCity, JobCountry, JobTittle FROM UserProfile WHERE UserName=@UserName", conn);

        cmdProfile.Parameters.AddWithValue("@UserName", userName);

        conn.Open();

        reader = cmdProfile.ExecuteReader();

        if (reader.Read())
        {
            labelName.Text = reader["Name"].ToString();
            txtBoxFather.Text = reader["Father"].ToString();
            TextBoxGender.Text = reader["Gender"].ToString();
            TextBoxAge.Text = "";
            TextBoxCity.Text = reader["City"].ToString();
            TextBoxCountry.Text = reader["Country"].ToString();
            TextBoxDepartment.Text = reader["Department"].ToString();
            TextBoxDegree.Text = reader["Degree"].ToString();
            TextBoxYear.Text = reader["Year"].ToString();
            TextBoxJobTittle.Text = reader["JobTittle"].ToString();
            TextBoxJobCity.Text = reader["JobCity"].ToString();
            TextBoxJobCountry.Text = reader["JobCountry"].ToString();
            TextBoxOrganization.Text = reader["Organization"].ToString();
        }

        conn.Close();
    } 

But it is not retrieving anything from database.

Actually I am taking userName parameter as query string from different page using this line

 userName = Request.QueryString["Name"].ToString();

When I put break points the control is not going forward after this line

if (reader.Read())

This is the page from where I am taking query string. .

<asp:GridView ID="GridAllAlumni" runat="server" 
        onitemcommand="GridAllAlumni_ItemCommand">
   <Columns>
      <asp:TemplateField>
         <ItemTemplate>
            <asp:LinkButton ID="lnkname" runat="server"
                            Text='<%#Eval("Name") %>'
                            PostBackUrl='<%#"~/Profile/Profile.aspx?Name="+Eval("Name") %>'/>
         </ItemTemplate>
      </asp:TemplateField>
   </Columns>
</asp:GridView>

Where am I getting wrong?

Your help will be appreciated. Thanx

Answer 1

Try this. I basically changed @UserName to :UserName in the query and removed the @ in the cmdProfile.Parameters.AddWithValue("@UserName", userName);. It worked for me. But, I may be wrong. So, feel free to correct me.

protected void LoadProfile()
{
        conn = new SqlConnection(connString);

        cmdProfile = new SqlCommand("SELECT Name, Father, Gender, UserName, City, Country, Department, Year, Degree, JobTittle, Organization, JobCity, JobCountry, JobTittle FROM UserProfile WHERE UserName=:UserName", conn);

        cmdProfile.Parameters.AddWithValue("UserName", userName);

        conn.Open();

        reader = cmdProfile.ExecuteReader();

        if (reader.Read())
        {
            labelName.Text = reader["Name"].ToString();
            txtBoxFather.Text = reader["Father"].ToString();
            TextBoxGender.Text = reader["Gender"].ToString();
            TextBoxAge.Text = "";
            TextBoxCity.Text = reader["City"].ToString();
            TextBoxCountry.Text = reader["Country"].ToString();
            TextBoxDepartment.Text = reader["Department"].ToString();
            TextBoxDegree.Text = reader["Degree"].ToString();
            TextBoxYear.Text = reader["Year"].ToString();
            TextBoxJobTittle.Text = reader["JobTittle"].ToString();
            TextBoxJobCity.Text = reader["JobCity"].ToString();
            TextBoxJobCountry.Text = reader["JobCountry"].ToString();
            TextBoxOrganization.Text = reader["Organization"].ToString();
        }

        conn.Close();
    }

It is while(reader.Read()) It is not looping.
