I have a datalist (dList3) inside another datalist (DataList1).  I need to reference a label control in the "inside" datalist (dList3).  I'm trying to do that in the DataList1_ItemDataBound but it is not working.  I'm assuming that is because the dlist3 hasn't been populated yet when calling DataList1_ItemDataBound.

Objective: To get the label "OpDisplay" which is a label in the DataList "dList3".

My Code:
Protected Sub DataList1_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.DataListItemEventArgs) Handles DataList1.ItemDataBound

        If e.Item.ItemType = ListItemType.Item Or _
            e.Item.ItemType = ListItemType.AlternatingItem Then
            Dim ds As SqlDataSource
            ds = CType(e.Item.FindControl("DetailsDataSource"),  _
                SqlDataSource)

            ds.ConnectionString = ConfigurationManager.ConnectionStrings("SQL2005_690222_ccmConnectionString").ConnectionString

            Dim categoryID As String
            categoryID = DataBinder.Eval(e.Item.DataItem, _
                "OrderID").ToString()
            ds.SelectParameters("OrdDetailOrderID").DefaultValue = _
                categoryID
        End If
        Dim lbDelType As Label = CType(e.Item.FindControl("OrderDelTypeLabel"), Label)
        Dim strABC = lbDelType.Text
       
        Dim dlList3 As DataList = CType(e.Item.FindControl("DataList3"), DataList)

        Dim lblOpDisplay() As Label

        Dim dlList3Count As Integer = dlList3.Items.Count
        For v = 1 To dlList3Count
            lblOpDisplay(v) = dlList3.Controls(v - 1).FindControl("OpDisplay")

            If lblOpDisplay(v).Text = "x" Then
                lblOpDisplay(v).Text = ""
            Else
                lblOpDisplay(v).Text = "Hello"
            End If
        Next

    End Sub

I figured it out.  Added " dlList3.DataBind()" to the code in "DataList1_ItemDataBound".
