Updating placeholder during runtime

[allstar11]

Hi Everyone, here is the problem I am having with placeholder:

I have a repeater and within that repeater, I have an item template. Now this template is formatted with a couple of tables, but for this question I have removed them to make things easier to read:

<asp:Repeater ID="Repeater1" OnItemDataBound="R1_ItemDataBound" runat="server">
        
   <ItemTemplate>
      <asp:PlaceHolder ID="phAnswers" runat="server"></asp:PlaceHolder>               
   </ItemTemplate>
</asp:Repeater>

Then, on the event OnItemDataBound , I create a new placeholder, bind it to the existing on (phAnswers), however the placeholder is not updated with the radiobuttons/textboxs that are created:

        Dim rdList As New RadioButtonList
        Dim newRadio As New RadioButton

 If (e.Item.ItemType = ListItemType.Item) Or _
            (e.Item.ItemType = ListItemType.AlternatingItem) Then

            Dim tempPH As PlaceHolder
 
            tempPH = e.Item.FindControl("phAnswers")

            For x As Integer = 0 To (t_MC.Count - 1)

                    newRadio = New RadioButton

                    newRadio.ID = "Answer" + x.ToString
                    newRadio.Text = t_MC(x).Value
                    rdList.Controls.Add(newRadio)

                Next

     tempPH.Controls.Add(rdList)

Any ideas why phAnswers is not updated with the new tempPH placeholder?
Cheers

Have you tried using a Panel instead of a Placeholder?

I don't think this is going to work out for you too well because of the way you are using/declaring your dynamic controls.
