    Hi I am learning to code in C#. But I am stuck at one place. I am trying to connect to SQL server through C#

    I am using VS 2005 and below is the code.

    using System;
    using System.Collections.Generic;
    using System.ComponentModel;
    using System.Data;
    using System.Drawing;
    using System.Text;
    using System.Windows.Forms;
    namespace WindowsApplication2
        public partial class Form1 : Form
            public Form1()
            System.Data.SqlClient.SqlConnection con;
            DataSet ds1;
            System.Data.SqlClient.SqlDataAdapter da;
            DataRow dRow;
            private void Form1_Load(object sender, EventArgs e)
                con = new System.Data.SqlClient.SqlConnection();
                ds1 = new DataSet();
                con.ConnectionString = "Data Source=.\\SQLEXPRESS;AttachDbFilename=C:\\TransNo.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True";
                string sql = "SELECT * From tblTransNo";
                da = new System.Data.SqlClient.SqlDataAdapter(sql, con);
                da.Fill(ds1, "TransNo");
            private void NavigateRecords()
                DataRow dRow = dsl.Tables["TransNo"].Rows[0];
                textBox1.Text = dRow.ItemArray.GetValue(2).ToString();
    Here are the errors I am getting

    Error 1 The name 'dsl' does not exist in the current context C:\Documents and Settings\User\My Documents\Visual Studio 2005\Projects\WindowsApplication2\WindowsApplication2\Form1.cs 40 28 WindowsApplication2
    Any help is appreciated.
