Dynamic Controls and Postback

I am creating a set of dynamic text boxes on my page.

When I do a postback the dynamic controls seem to always disappear. I have
tried setting the EnableViewstate = True and still no luck. I would like
them to remain and persist any data entered by the user on postback.

Any ideas?

Steve,

They'll need to be recreated everytime. The veiwstate only stores
information about the control, not the control it self.

Yeah, that's what conclusion I seemed to come to but thought I'd see if I
was missing something. Here is some code for basically how I solved it.

ASPX PAGE

<body>
<form id="Form1" method="post" runat="server">
<asp:Button Runat=server ID=btnAdd Text=Add />
<asp:Button Runat=server ID=btnPost Text=Post/>
<asp:PlaceHolder ID=place Runat=server EnableViewState=True />
</form>
</body>


CODE BEHIND

Private Sub Page_Init(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Init
'CODEGEN: This method call is required by the Web Form Designer
'Do not modify it using the code editor.
InitializeComponent()

'--> RECREATE DYNAMIC CONTROLS IF NEEDED <--
If Request.Form("txtb") <> "" Then
Dim txtbox As New TextBox
txtbox.Text = Request.Form("txtb")
txtbox.ID = "txtb"
txtbox.EnableViewState = True

Me.place.Controls.Add(txtbox)

End If
End Sub

Private Sub btnAdd_Click(ByVal sender As Object, ByVal e As
System.EventArgs) Handles btnAdd.Click
Dim txtbox As New TextBox
txtbox.Text = Now.ToString
txtbox.ID = "txtb"
txtbox.EnableViewState = True

Me.place.Controls.Add(txtbox)

End Sub
