I have a page which I dynamically add several usercontrols (*.ascx files) to 
using the following code:


 Public Sub Refresh()
  For Each section As DataRow In Me.GetSections().Rows
   CType(Me.FindControl("admin" & CStr(section("buttontext")).Replace(" ", 
"")), adminsection2).RefreshSection()
  Next
 End Sub

 Protected Sub Page_Load(ByVal sender As Object, ByVal e As 
System.EventArgs) Handles Me.Load
  Dim sections As DataTable = Me.GetSections()
  For Each section As DataRow In sections.Rows
   Me.AddAdminSection(CStr(section("buttontext")))
  Next
  Me.Refresh()
 End Sub

 Private Function GetSections() As DataTable
  Dim sections As New DataTable
  Dim dataadapterSelect As New OleDbDataAdapter("SELECT buttontext FROM 
subnavigation WHERE buttontext<>'More.' AND category='" & 
Request.QueryString("category") & "' ORDER BY buttonorder", 
System.Configuration.ConfigurationManager.AppSettings("connectionstring"))
  dataadapterSelect.Fill(sections)
  Return sections
 End Function

 Private Sub AddAdminSection(ByVal section As String)
  Dim admin As adminsection2 = 
CType(Page.LoadControl("~/usercontrols/adminsection2.ascx"), adminsection2)
  admin.ID = "admin" & section.Replace(" ", "")
  admin.Section = section
  Me.form1.Controls.Add(admin)
 End Sub


My problem is that the controls are reloaded every time, as you can see from 
the Load event. If I place the following line

Me.AddAdminSection(CStr(section("buttontext")))

in an If Not Me.IsPostBack() statement, then it is only loaded the first 
time and I recieve an object does not exist error every time the Refresh() 
method is called (which is reasonably often, because this is for an 
administration page where the user edits DB records). What can I do to 
maintain the look of the dynamically added controls (in other words, how can 
I avoid replacing them with every postback)? If there is any other code you 
need to see that might help, let me know. Thanks.

Hi,

Dynamically loaded controls need to be load after each post back...
other wise dynamically loaded control's event wont work...
Its always a good practice to load the controls in page_init event

Thanks

Isn't there any kind of workaround? I am sure that I am not the first person 
to want to maintain the properties of dynamically loaded usercontrols 
between postbacks. Anybody have any ideas? Thanks.

Nathan,

Probably Ajax,  however I am seriously curious what a usercontrol for ASPNET 
has to do with ADONET.

You have to load dynamically added controls each time. Their properties are 
mantained as with static controls.

The dynamically added usercontrols that I want to maintain the look of 
contain AJAX, and the reason for the postbacks is to update the data 
accessed using ADO.NET, so there are your relations to AJAX and ADO.NET. The 
main tags in the usercontrol are the following:

<asp:Panel>
     <asp:Label/>
</asp:Panel>
<asp:Panel>
     <asp:DataList>
     </asp:DataList>
</asp:Panel>
<AJAX:CollapsiblePanelExtender/>

(obviously the controls all have their properties, and the DataList has it's 
ItemTemplate and EditItemTemplate). The property that I am having trouble 
maintaining is the Collapsed property of the CollapsiblePanelExtender 
control. The postbacks are usually caused by eventbubbling through Button 
controls in the DataList. I haven't tried it yet, but one idea I thought 
about was to put the DataList inside an UpdatePanel. The only concerns I had 
with this idea were:

1. In some cases, a record is moved from the DataSource of one DataList to 
the DataSource of another DataList. This would mean I would still need a way 
to update all the DataLists regardless. Any ideas to make this possibility 
work?

2. There is one section that on the page (not in the usercontrols, but on 
the page that contains the usercontrols) that is used to add records, 
obviously causing a postback. This would cause pretty much the same 
situation as Concern #1, and would probably be solved in a similar way. Any 
ideas for this?

The code I currently use to update the usercontrols is the following. The 
*.ascx.vb file contains the following method, which is called for all of the 
usercontrols from a method in the containing page (I removed the 
OleDbDataAdapter's SQL to keep the code short in the posting):

Public Sub RefreshSection()
 Dim sectiontable As New DataTable
 Dim sectionadapter As New OleDbDataAdapter("", 
ConfigurationManager.AppSettings("connectionstring"))
 sectionadapter.Fill(sectiontable)
 Me.datSection.DataSource = sectiontable
 Me.datSection.DataBind()
End Sub

Do any of these ideas or information help give a way to solve my problem? 
Thanks.

Nathan,

We have used that on our VB-Tips website, however I have not enough time to 
get a nice sample from that.  Why don't you make for your self a simple 
sample only containing your problem.

You will find that you than find the solution.

We have used that on our VB-Tips website, however I have not enough time to
