WinForms Binding to sub property and binding sub controls in a data repeater?

[i00]

This is WinForms BTW:

... just say I have an object that is like this:

Public class Address
    Public Property UnitNo as integer
    Public Property HouseNo as integer
    Public Property Street as string
    '....
end class
Public class Person
    Public Property FirstName as string
    Public Property Address as new Address
End Class

Just wondering if it's possible to bind to the Persons.street in a data repeater??

The following works fine ... until it's in a data repeater and then it doesn't work:

TextBox1.DataBindings.Add(New Binding("Text", bs, "Address.Street", False, DataSourceUpdateMode.OnPropertyChanged))

...Also the same also seems to apply for sub controls in a data repeater... (in the case below MyTestControl is a control on the data repeater that exposes TextBox1 that is on it this applies when you don't try to bind to a sub property on the bs):

MyTestControl.TextBox1.DataBindings.Add(New Binding("Text", bs, "FirstName", False, DataSourceUpdateMode.OnPropertyChanged))

Any ideas? ... This is really frustrating@!
Thanks,

I have attached a test case project here so that you can see what I mean:

The only way I can work out of doing it is manually binding on the DrawItem event ... would be nice to do it on the ItemCloned event ... but the e.DataRepeaterItem.ItemIndex is always 0 when that happens

Would be nice if they had an ItemDataSet event or something so I could do it there.

Private Sub DataRepeater1_DrawItem(sender As Object, e As PowerPacks.DataRepeaterItemEventArgs) Handles DataRepeater1.DrawItem
        Dim ctl = e.DataRepeaterItem.Controls.OfType(Of UserControl1)().FirstOrDefault()
        If ctl IsNot Nothing Then
            Dim theObject = bs(e.DataRepeaterItem.ItemIndex)
            If ctl.TextBox1.DataBindings.Count = 0 Then
                ctl.TextBox1.DataBindings.Add(New Binding("Text", theObject, "Name", False, DataSourceUpdateMode.OnPropertyChanged))
            End If
        End If
 
    End Sub

Any better ideas?
