Dynamic control in VB.NET - vb.net

Question

This is my code for dynamic textbox controls in button click event. The code is working well. If i click the button 3 times, it is generated 3 text boxes. But I have no idea to assign text box values to a variable. I dont know the names of dynamic generated controls. if i want to add value to 3rd text box, how to do it?
Dim txtBx As TextBox
Static x As Integer
Static i As Integer
txtBx = New TextBox
txtBx.Location = New Point(10, 10 + x)
txtBx.Size = New Size(100, 20)
i = i + 1
x = x + 20
Me.Controls.Add(txtBx)
if i create normal textbox i can do it with,
TextBox3.Text = "Some value"
But I dont know to do this for dynamic controls.

Here's an example, storing the references in a List(Of Textbox):
Public Class Form1
Private tbList As New List(Of TextBox)
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
Dim tb As TextBox
Dim n As Integer
n = tbList.Count + 1
tb = New TextBox
With tb
.Location = New Point(10, 10 + (n * 20))
.Name = "dynTB" & n.ToString
.Size = New Size(100, 20)
End With
Me.tbList.Add(tb)
Me.Controls.Add(tb)
End Sub
Private Sub Button2_Click(sender As System.Object, e As System.EventArgs) Handles Button2.Click
' Testing:
If Me.tbList.Count >= 3 Then Me.tbList(2).Text = "This is textbox 3"
End Sub
End Class
