Databinding to dropdowntree is not working

[Justin]

Here's my code:

Protected Sub Page_Load(sender As Object, e As EventArgs) Handles Me.Load
            If Not IsPostBack Then
                Load_ddlGroupName()
            End If
        End Sub

Private Sub Load_ddlGroupName()
            ddlGroupName.DataTextField = "FinanceNumberName"
            ddlGroupName.DataValueField = "FinanceNumberName"
            ddlGroupName.DataFieldParentID = "VP"
            ddlGroupName.DataFieldID = "FinanceNumberName"
            ddlGroupName.DataSource = (From d In DbContext.FPRDropDownLists Select d).ToList() 'verified datasource is populated.
            ddlGroupName.DataBind()
        End Sub

What am I missing?
