So, if you are retrieving data from DatatTable, then can you show that code please ?
I need to see how exactly you get data and show in textbox.

<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);

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

con.Close();
con.Dispose();

}
}
private void navigo()
{

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