Tree view showing full hierarchy

Hi everyone, Thanks in advance for helping. I am new to tree views and trying to get a simple hierarchy (from the account dimension) to show as a tree view. Part of the structure is shown in the ...

    I like to use recursive functions for things like this. Not sure if there is a more out of the box way as I haven't done a lot with treeviews.

    I asked AI to turn your code into a recursive function. No idea if it works but it might set you on the path.

    Sub BuildTree(ByVal si As SessionInfo, ByVal DimPk As DimPk, ByVal parentMbrId As Integer, ByVal parentMbrName As String, ByVal parentMbrDescription As String, ByVal textColour As String, ByVal imageSource As String, ByVal imageName As String, ByVal isBold As Boolean, ByVal isEnabled As Boolean, ByVal isSelected As Boolean, ByVal isExpanded As Boolean, ByVal treeCollection As XFTreeItemCollection)
    'Declare the child list of the parent
    Dim childList As List(Of Member) = BRApi.Finance.Members.GetChildren(si, DimPk, parentMbrId)
    'Dim the new XFTreeItem List
    Dim treeChildren As New List(Of XFTreeItem)()

    'Loop through the children
    For Each child As Member In childList
        ' Recursively build children of children
        Dim childTreeCollection As New XFTreeItemCollection()
        BuildTree(si, DimPk, child.Id, child.Name, child.NameAndDescription, textColour, imageSource, imageName, isBold, isEnabled, isSelected, isExpanded, childTreeCollection)
        ' Create XFTreeItem for current child and add children to it
        Dim childTreeItem As New XFTreeItem(child.Name, child.NameAndDescription, textColour, isBold, isEnabled, isSelected, isExpanded, imageSource, imageName, child.Name, childTreeCollection)
        treeChildren.Add(childTreeItem)
    Next

    ' Add the children to the parent
    Dim parentTreeItem As New XFTreeItem(parentMbrName, parentMbrDescription, textColour, isBold, isEnabled, isSelected, isExpanded, imageSource, imageName, parentMbrName, treeChildren)
    treeCollection.TreeItems.Add(parentTreeItem)
End Sub

' Usage:
Dim DimPk As DimPk = BRApi.Finance.Dim.GetDimPk(si, "actAccount")
Dim parentMbrId As Integer = BRApi.Finance.Members.GetMemberId(si, dimTypeId.Account, "CF_000000")
Dim parentMbr As Member = BRApi.Finance.Members.GetMember(si, dimTypeId.Account, parentMbrId)
Dim textColour As String = XFColors.Black.Name
Dim imageSource As String = XFImageFileSourceType.ClientImage
Dim imageName As String = XFClientImageTypes.StatusGrayBall.Name
Dim isBold As Boolean = False
Dim isEnabled As Boolean = True
Dim isSelected As Boolean = False
Dim isExpanded As Boolean = True
Dim treeCollection As New XFTreeItemCollection()
BuildTree(si, DimPk, parentMbrId, parentMbr.Name, parentMbr.NameAndDescription, textColour, imageSource, imageName, isBold, isEnabled, isSelected, isExpanded, treeCollection)
