How to make composite User Control VB.NET

<Serializable()>    
Public Class PersonNameOnly
   
    Private p_Name As String = ""
    Public Sub New()
        ' needed for deserialization
    End Sub

    Public Property Name As String
        Get
            Return p_Name
        End Get
        Set(value As String)
            p_Name = value
        End Set
    End Property
End Class 

[WinForm]

The PersonNameOnly Class above is bonded Type of BindingSource on the PersonUsercontrolForPersonWithNameOnly user control, the name is bonded to a Textbox.

MainUsercontrolForPersonWithNameOnly has a collection of the PersonUsercontrolForPersonWithNameOnly

All the Above Works Fine in the Existing app.

I need new to create a new Form MainUsercontrolForPersonWITHIMAGE So I have created a new UserControl that inherits PersonUsercontrolForPersonWithNameOnly and added a Label that holds the ImageUrl, so This is what I've done so far below.

<Serializable()>
Public Class PersonWITHIMAGE
    Inherits PersonNameOnly
    Private p_ImageUrl As String = ""
    Public Sub New()
        ' needed for deserialization
    End Sub

    Public Property ImageUrl As String
        Get
            Return p_ImageUrl
        End Get
        Set(value As String)
            p_ImageUrl = value
        End Set
    End Property
End Class 

[WinForm]

<Global.Microsoft.VisualBasic.CompilerServices.DesignerGenerated()>
Partial Class PersonUsercontrolForPersonWITHIMAGE 
    Inherits PersonUsercontrolForPersonWithNameOnly 

How Can I Merge the two data binding as if it was one source, I manage to get the Name only to work on the top-level form with the collection but am not sure how to merge the data in sync with the name only User Control.

How Can I merge the two data binding in once composite form?
