Making a comboxbox bound to the property with reference type

Question

I created two classes: Person and Expense in which an expense might have at most a reposible person.

VB

Public Class Person
  ...
End Class

Public Class Expense
  Private m_descr  As String 'Describe the expense
  Private m_amount As Double 'Amount expensed
  Private m_person As Person 'A person who is responsible for an expense

  Public Property Description() As Double ... End Property
  Public Property Amount() As Double ... End Property
  Public Property Person() As Person ... End Property
  ...
End Class

If I want to bind the property Parent of an expense to a Combox with dropdonw items bound to a list of Persons, How can I do (in VB.Net) in order to change the responsible person of this expense when a person in the dropdown of this combobox was chosen?

If you want to bind combobox to your class, your class needs to implement IList[^] Interface.
This links would be helpful too:

If you want to change Person for Expense, change the Person property:

VB

Public Property Person(ByVal _person As Person) As Person
    Get
        Return m_Person
    End Get
    Set(ByVal _person As Person)
        m_Person = _person
    End Set
End Property
