if im not mistaken, you can also do this
Dim txtTest As New TextBox
* * Private Sub Page_Init(ByVal sender As Object, ByVal e As
System.EventArgs) Handles Me.Init
* * * *
* * * * PlaceHolder1.Controls.Add(txtTest)
* * End Sub
* * Private Sub Button1_Click(ByVal sender As Object, ByVal e As
System.EventArgs) Handles Button1.Click
* * * * Response.Write("Value for dynamic textbox = " & txtTest.Text)
* * End Sub
