Can you please point me to the right direction

Thanks Nikola

That works

Another question - how can I change images (+, -) in codebehind?

Thanks,

Vladimir

Sure, here it is:

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
  If Not Me.Page.IsPostBack Then

   SetupDataSource()

   Dim view As DataView
   view = New DataView
   view.ID = "DefailtView"
   view.DataSourceID = Me.AccessDataSource1.ID
   view.DataMember = "DefailtView"
   Me.WebHierarchicalDataSource1.DataViews.Add(view)

   Dim relation As DataRelation
   relation = New DataRelation

   relation.ChildColumns = New String() {"ParentCode"}
   relation.ChildDataViewID = view.ID
   relation.ParentColumns = New String() {"Code"}
   relation.ParentDataViewID = view.ID

   Me.WebHierarchicalDataSource1.DataRelations.Add(relation)
   Me.WebDataTree1.InitialDataBindDepth = 0
   Me.WebDataTree1.DataLoadingMessage = "Loading from table ..."
   Me.WebDataTree1.DataSourceID = Me.WebHierarchicalDataSource1.ID
  End If
 End Sub

 Protected Sub WebDataTree1_NodePopulate(ByVal sender As Object, ByVal e As Infragistics.Web.UI.NavigationControls.DataTreeNodeEventArgs) Handles WebDataTree1.NodePopulate
  SetupDataSource()
 End Sub

 Private Sub SetupDataSource()
  Me.AccessDataSource1.DataFile = "~/App_Data/TreeData.mdb"
  Me.AccessDataSource1.SelectCommand = "SELECT [Code], [TextValue], [ParentCode] FROM [Data]"

  Dim binding As DataTreeNodeBinding
  binding = New DataTreeNodeBinding
  binding.DataMember = "DefailtView"
  binding.TextField = "TextValue"
  binding.ValueField = "Code"
  Me.WebDataTree1.DataBindings.Add(binding)
 End Sub

Hope that helps!

could you prived the final codebehind code?

Hi Vladimir,

when using the code-behind  you should also bind the tree on the NodePopulate event.
