How to Display Records as First-Next-Previous-Last in a Textboxes Using Windows Application

Above ds.Tables[0].Rows.Count means it counts number of records presnt in a table.

The Complete coding in Form1.cs as follows:-

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Data.Odbc;
using System.IO;
namespace WindowsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
OdbcDataAdapter da;
DataSet ds;
int i = 0;
int j;
OdbcConnection conn;
int last;
private void Form1_Load(object sender, EventArgs e)
{
conn = new OdbcConnection("dsn=t1");
conn.Open();
da = new OdbcDataAdapter("select * from emp", conn);
OdbcCommandBuilder builder = new OdbcCommandBuilder(da);
ds = new DataSet();
da.Fill(ds, "emp");
dataGridView1.DataSource = ds.Tables["emp"];
}

private void btnfirst_Click(object sender, EventArgs e)
{
if (ds.Tables[0].Rows.Count > 0)
{
i = 0;
textBox1.Text = ds.Tables[0].Rows[i]["ID"].ToString();
textBox2.Text = ds.Tables[0].Rows[i]["empname"].ToString();
textBox3.Text = ds.Tables[0].Rows[i]["salary"].ToString();
}
}
private void btnlast_Click(object sender, EventArgs e)
{
i = ds.Tables[0].Rows.Count - 1;
textBox1.Text = ds.Tables[0].Rows[i]["ID"].ToString();
textBox2.Text = ds.Tables[0].Rows[i]["empname"].ToString();
textBox3.Text = ds.Tables[0].Rows[i]["salary"].ToString();

}
private void btnnext_Click(object sender, EventArgs e)
{

if (i < ds.Tables[0].Rows.Count - 1)
{
i++;
textBox1.Text = ds.Tables[0].Rows[i]["ID"].ToString();
textBox2.Text = ds.Tables[0].Rows[i]["empname"].ToString();
textBox3.Text = ds.Tables[0].Rows[i]["salary"].ToString();
}
else
{
}
}
private void btnprevious_Click(object sender, EventArgs e)
{
if (i == ds.Tables[0].Rows.Count - 1 || i != 0)
{
i--;
textBox1.Text = ds.Tables[0].Rows[i]["ID"].ToString();
textBox2.Text = ds.Tables[0].Rows[i]["empname"].ToString();
textBox3.Text = ds.Tables[0].Rows[i]["salary"].ToString();
}
else
{
}
}
}
