I want to try and hook into the URLControl to set the default Link Type to be something else, but I didn't notice any exposed properties or methods to allow me to do this.  Instead, I began writing a loop to find the correct control (optType).  I did this successfully, but during the "LoadSettings" method of the Settings page cycle, the items are not yet bound to the optType RadioButtonList. 

Does anyone have any ideas about how I can do this?

Here is my example code (with traces still in place):

Dim ctlRadio As System.Web.UI.WebControls.RadioButtonList
Dim ctl As System.Web.UI.Control
Dim ctlInner As System.Web.UI.Control
Dim ctlInnerInner As System.Web.UI.Control

' look for the URL type control
Try
    For Each ctl In Me.ctlURL.Controls
        Trace.Warn("A Control is found.")
        Trace.Warn("ctl.GetType.ToString = " & ctl.GetType.ToString)
        If ctl.HasControls Then
            Trace.Warn("This Control has controls.")
                        For Each ctlInner In ctl.Controls
                            Trace.Warn("Begin INNER LOOP")
                            Trace.Warn("ctlInner.GetType.ToString = " & ctlInner.GetType.ToString)
                            Trace.Warn("ctlInner.HasControls = " & ctlInner.HasControls.ToString)
                            If ctlInner.GetType.ToString = "System.Web.UI.HtmlControls.HtmlTableCell" Then
                                Trace.Warn("The INNER INNER loop is next")
                                Trace.Warn("ctlInner.HasControls = " & ctlInner.HasControls.ToString)
                                For Each ctlInnerInner In ctlInner.Controls
                                    Trace.Warn("Begin INNER INNER LOOP")
                                    Trace.Warn("ctlInnerInner.GetType.ToString = " & ctlInnerInner.GetType.ToString)
                                    If ctlInnerInner.GetType.ToString = "System.Web.UI.WebControls.RadioButtonList" Then
                                        Trace.Warn("'====================================================='")
                                        Trace.Warn("THIS CONTROL IS THE RIGHT TYPE!!!")
                                        ' this is a radiobuttonlist
                                        ctlRadio = CType(ctlInnerInner, System.Web.UI.WebControls.RadioButtonList)
                                        Trace.Warn("... ctlRadio.Items.Count = " & ctlRadio.Items.Count)
                                        Trace.Warn("... ctlRadio.ID = " & ctlRadio.ID)
                                        ' if you uncomment this, it will throw an exception because the required
                                        ' items have not yet been bound to the radiobuttonlist control
                                        'ctlRadio.Items.FindByText(Localization.GetString("TabType.Text", _
                                        '    Me.ctlURL.LocalResourceFile)).Selected = True
                                        Trace.Warn("'====================================================='")
                                    End If
                Next
                Trace.Warn("End INNER INNER loop")
            End If
        Next
        Trace.Warn("End INNER LOOP")
    End If
Next

[EDIT]
It would be MUCH nicer if the core simply exposed a new property or method to allow us to change the default.  I could do it, but I refrain from modifying the core as much as possible.  :)
