Start Treeview collapsed

Hi all, I have a hopefully simple one, when I start my page it starts with my treeview fully expanded. I want it to start at 1 level down. I have tried loading into my
page_load
TreeView1.Nodes(1).CollapseAll
and I tried
TreeView1.Nodes(1).Expanded = False
I tried changing various variables in properties, but no help...
This is loaded in the MasterPage and uses a SiteMapDataSource with a web.sitemap...
Thanks,
Randy

If you you want the first level and it's children visible you can do it like this:

Dim node, node2 As TreeNode
For Each node In Treeview1.Nodes
For Each node2 In node.ChildNodes
node2.CollapseAll()
Next
Next

If you just want the first level you do:

Treeview1.CollapseAll()

It does not seem to make a difference...
But I did notice that the Treeview1.Nodes count is 0

Ok, you're doing this too early.

You must do it after the databinding is done. Do it in Page_PreRender instead.

Here is a section of my Web.sitemap, perhaps I am not entering the different nodes correctly...

<siteMapNode url="http://web1/" title="Home"  description="">
      <siteMapNode url="Accounting\AccountingHome.aspx" title="Accounting"  description="">
        <siteMapNode url="PaymentStatus\AP_PaymentStatus.aspx" title="AP Payment Status"  description="">
        </siteMapNode>            
        <siteMapNode url="http://web1/HydroChemWebsite/Accounting/SupplierContactList.xls" title="Supplier Contact List"  description="">
        </siteMapNode>
      </siteMapNode>
      <siteMapNode url="AllianceGroup\AllianceGroupHome.aspx" title="Alliance Group"  description="">
        <siteMapNode url="http://AllianceContacts.asp?Section=Alliance" title="Contacts"  description="">
        </siteMapNode>       
        <siteMapNode url="http://Reports/Report_CustomerOT.aspx" title="Customer OT Rpt"  description="">
        </siteMapNode>
      </siteMapNode>
</siteMapNode>

I changed it to there and get the same result. In the
For Each node In TreeView1.Nodes
there are 0 nodes at that point, so it just skips right on by that and its inner loop..

Thanks, that one worked. I could have sworn I had already tried that one, but I have been messing with several of them, so I probably changed it and then tested it in a different one than the one I had changed it in.
Thanks for the great help!!
