Maintaining dynamic controls

[ma77c]

I'm trying to maintain user controls that are added dynamically when the user selects a menu item. To do this, I've created an ArrayList and I add the appropriate usercontrol depending on the menu item selected. I then call a loadControls() method on page load to add the controls to a placeholder. However, I am left with only the most recently added control.

Can anyone see what I'm doing wrong or missing?

Private Shared entryItemsArray As New ArrayList()
Private Shared itemCount As Integer = 0

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
    loadControls()
End Sub

Protected Sub loadControls()
    For Each obj As Object In entryItemsArray
        If (obj.GetType().FullName = "ASP.Paragraph_ascx") Then
            Dim p As ASP.Paragraph_ascx = CType(obj, ASP.Paragraph_ascx)
            Dim id As String = p.ID
            Dim txt As String = p.Text
            phEntryItems.Controls.Add(p)
        ElseIf (obj.GetType().FullName = "ASP.List_ascx") Then
            Dim l As ASP.List_ascx = CType(obj, ASP.List_ascx)
            phEntryItems.Controls.Add(l)
        End If
    Next
End Sub

Protected Sub menuEntryItems_MenuItemClick(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.MenuEventArgs) Handles menuEntryItems.MenuItemClick
    Select Case menuEntryItems.SelectedValue
        Case "addPara"
            Dim p As ASP.Paragraph_ascx
            p = CType(LoadControl("~/Paragraph.ascx"), ASP.Paragraph_ascx)
            p.ID = "p" & itemCount.ToString
            p.Text = "p" & itemCount.ToString 'for testing purposes
            entryItemsArray.Add(p)
            phEntryItems.Controls.Add(p)
            itemCount += 1
        Case "addList"
            Dim l As ASP.List_ascx
            l = CType(LoadControl("~/List.ascx"), ASP.List_ascx)
            l.ID = "l" & (itemCount + 1).ToString
            entryItemsArray.Add(l)
            phEntryItems.Controls.Add(l)
            itemCount += 1
    End Select
End Sub

The controls collection of the placeholder, phEntryItems, contains all of the user controls, but it only displays the control that was added last.

Can anyone explain this behaviour?

Is my description not good enough or am I simply beyond help.

Place the call to loadcontrols() in the Page_Init event, insted of page_load
