Default TextBox inside GridView

Hi I am really a beginner in ASP.NET so I am sorry for possible stupid question.
I have GridView on the form, inside GridView I have a textBox, I am trying to get textBox.text and for some reason I am getting empty string. Here is the code example:

.aspx Page

<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Default.aspx.vb" Inherits="_Default" EnableEventValidation="false" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
    <title>Untitled Page</title>
    <form id="form1" runat="server">
<asp:GridView runat="server"
    <EmptyDataRowStyle BackColor="AliceBlue" />
    <Columns >
    <asp:BoundField DataField="CompanyName" ItemStyle-Width="200" />
    <asp:TemplateField ItemStyle-Width="200" Visible="true" >
        <ItemTemplate >
            <asp:TextBox runat="server" id="txt1" Rows="3">
        </ItemTemplate >
    <br />
    <br />
    <asp:Button runat="server" ID="btText" />

.aspx.vb page

Imports System.Data
Imports System.Data.SqlClient
Partial Class _Default
    Inherits System.Web.UI.Page
    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        Dim connection As SqlConnection = New SqlConnection("Persist Security Info=False;Integrated Security=true;Initial Catalog=Northwind;server=(local)")
        Dim adapter As SqlDataAdapter = New SqlDataAdapter("SELECT CustomerID,CompanyName,Address from Customers", connection)
        Dim table As DataTable = New DataTable("Table")
        Dim dataSet As DataSet = New DataSet("dataSet")
        Dim dv As DataView = table.DefaultView
        test1.DataSource = dv
    End Sub
    Protected Sub test1_PageIndexChanging(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewPageEventArgs) Handles test1.PageIndexChanging
        test1.PageIndex = e.NewPageIndex
    End Sub
Protected Sub btText_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btText.Click
        For Each curRow As GridViewRow In test1.Rows
            Dim strR As String = CType(curRow.FindControl("txt1"), TextBox).Text
            Response.Write("TEST : " & strR & "<br>")
    End Sub

End Class

Stick the whole chunk of logic where you populate the dataset and bind the GridView to it inside an

If IsPostBack=False then
     'Code to populate dataset and bind to GridView here
End If
...and you should be in business.
