When i load the page, i wanted the treelist had default selection node : 2, 2.1, 2.2, 3, 3.2

Answer 1

i had solved my problem. here the answer i created :

    Dim iterator As TreeListNodeIterator = tree1.CreateNodeIterator()
    Dim node As TreeListNode
    Dim foundRow As DataRow
    Do While Not (_database Is Nothing)
        node = iterator.GetNext()
        If node Is Nothing Then
            Exit Do
        End If
        foundRow = _database.Rows.Find(node.Key)
        If Not (foundRow Is Nothing) Then
            node.Selected = True
        End If

    Loop

_database is a datatable which i used to collect the value on my database.
