How to bind to a RadTreeview

[Rob Venable]

Hi,
I have a query (CTE) that returns the parent child relationship in a dataset and I can bind to an ASP.Net treeview but I want to be able to bind to a RadTreeView. Can anyone help me with the conversion?
Here's my code to bind to a treeview:

 Private Sub InitializeControls()

        '==Get some info from the logged in user
        Dim oContact As New Contact(UserInstance.ContactID)
        '== Labels
        lblDownline.Text = "My Distributor Downline"

        LoadDataSet()
        '== If it's the root node, SponsorID will be zero so use their contactid
        Dim parentID As Integer = 0
        If oContact.SponsorID = 0 Then
            parentID = UserInstance.ContactID
        Else
            parentID = oContact.SponsorID
        End If

        BuildTree(TreeView1.Nodes, parentID)

    End Sub

    Private Sub LoadDataSet()
        '==ds is declared at the page level
        Dim oContacts As New ContactCollection
        ds = oContacts.GetDownline(UserInstance.ContactID, 8) '==returns a dataset...later would like to return a collection

    End Sub

Private Sub BuildTree(ByVal nodes As TreeNodeCollection, ByVal IntParent As Int32)
        Dim thisID As Int32
        Dim thisName As String
        Dim children As DataRow() = ds.Tables(0).Select("SponsorID='" & IntParent & "'")

        If children.Length = 0 Then
            Return
        End If
        Dim newNode As TreeNode
        For Each child As DataRow In children
            thisID = Convert.ToInt32(child.ItemArray(0))
            thisName = Convert.ToString(child.ItemArray(2))
            newNode = New TreeNode(thisName, thisID.ToString)
            nodes.Add(newNode)
            newNode.ToggleExpandState()
            BuildTree(newNode.ChildNodes, thisID)

        Next
    End Sub

Does anyone know how to do this with a RadTreeView? I almost had it working but the newNode doesn't have a ChildNodes collection.

Thanks

Hi Rob Venable,

You need to use the Nodes collection instead of ChildNodes (which does not exist).

Thanks Veskoni. I thought I tried this before but it works now.
