Because you add the control dynamically to the control collection, it does
not get added to that same collection on postback. If you want to have it
there, then you need to add it each time, regardless of whether it is
postback or not. And, depending on what you are going to do with the
control, you may want to add it in the init event of the page so it can get
processed properly.

Subject: [DOTNET] Dynamically added controls not visible on PostBack
Hi:
I have a placeholder on my webform, to which I add WebControls
dynamically.
The controls are added and appear fine on the form. The problem I
notice is
that when I post the form, I can't access these controls server-side.
e.g.)
If Page.IsPostBack Then
' on submit - check for value
Debug.Write ph.Controls.Count ' <-- this is 0
Debug.Write Request.Form("test") ' <-- this is ok - it finds it
(?)
Else
Dim txt As TextBox = New WebControls.TextBox()
txt.ID = "test"
txt.Text = "test"
' add to placeholder on form
ph.Controls.Add(txt)
End If
Why can't I see the controls added to the PlaceHolder control? Is there
a
way to set the runat="server" for these added controls to force them to
post
back?
Thanks!
