Binding a textbox on another tabpage

Hello,

I have a tabcontrol with 4 tabpages with some textboxes on each tabpage.These textboxes are binded to a datatable.All the data appears well in each textbox but when i want to access the text property of the textboxes alle the values are empty except the text propertys on tabpage 1?Why is that?

Here is some code:

public partial class Form1 : Form

public DataSet ds = new DataSet();

public DataTable dt = new DataTable();

public BindingSource binding1 = new BindingSource();

public Form1()

try

string connectString = "Persist Security Info=False;User ID=gerry;Password=3600gerry;Initial Catalog=BROEKX_038951_311;Data Source=webdata99.broekx.be";

string sql = "Select * From [038951_311_PERSON_PERSON]";

using (SqlConnection connection = new SqlConnection(connectString))

SqlDataAdapter dataAdapter1 = new SqlDataAdapter(sql, connection);

dataAdapter1.Fill(ds, "038951_311_PERSON_PERSON");

dt = ds.Tables["038951_311_PERSON_PERSON"];

catch (SqlException sqlex)

MessageBox.Show(sqlex.Message, "Error");

catch (Exception ex)

MessageBox.Show(ex.Message, "Error");
