<pre> protected void Page_Load(object sender, EventArgs e)
if (!Page.IsPostBack)
con = new OleDbConnection();
con.ConnectionString = "Provider=SQLOLEDB; Data Source=; Initial Catalog=; User ID=; Password=";
ds = new DataSet();

string sql = "SELECT * From Customer";

da = new OleDbDataAdapter(sql, con);

da.Fill(ds, "Customer");
MaxRows = ds.Tables["Customer"].Rows.Count;


private void navigo()

txt_code.Value = ds.Tables["Customer"].Rows[count]["Code"].ToString();
txt_desc.Value = ds.Tables["Customer"].Rows[count]["Description"].ToString(); </pre>

on the click of save button write dowo following code

 cmd=new SQlcommand("update tablename set columnname='"+textbox.text +"' where id='"+id+"'",con);;

where con is connection object
cmd in sqlcommand object
id is the primary key for which row you want to update
