I need to know how to maintain de status (nodes expanded and selected) of a
treeview in a master page.
I have a master page with a treeview. I have a default page, when the
treeview is expanded and a node is selected then redirects to a another page
Response.Redire ct("Page2.aspx" )
And run's ok, but the treeview in this page is colapsed. The treeview
maintain its aspect, the images for the nodes, etc, but is colapsed and
nothing node is selected
Many thanks for your help

Juanjo,
Store the selected node number in viewstate and on page loads check that
viewstate parameter and if a selected node exists set the treeview to
display it as selected.

OK Justin,
I do it.
In the master page code
Protected Sub TreeView1_Selec tedNodeChanged( ByVal sender As Object, ByVal e
As System.EventArg s) Handles TreeView1.Selec tedNodeChanged
ViewState("Sele ctedNode") = TreeView1.Selec tedNode.Value
Response.Redire ct("Page2.aspx" )
End Sub
And in the Page2_Load
If Me.ViewState("S electedNode").T oString = "Perfiles" Then
'Code for selected node
End If
But now the problem is that ViewState("Sele ctedNode") is nothing. Not exists
What I'm doing wrong?

Juanjo,
A response.redire ct clears the viewstate. Either store the parameter in a
session variable (if that will be allright for your application) or use
Server.Transfer and store the value in a context variable instead. If you
need any clarification on how session variables or server.transfer and the
context object works let me know.

Exists another way to load the page2.aspx without response.redire ct command?

Juanjo,
Yes, the other way is to use Server.Transfer .

I use "Response.Cache.SetCacheability(HTTPCacheability.NoCache)" to force a

really want to reload the page since the data may still be inconsistent, if
the page was called from a url and based on values in a querystring.
