How to signal the Close event of a a MDI child frame to the parent frame

Listen for the close event on the object in the parent.

Dim ofrm as new form
addhandler ofrm.Close, addressof childforms_closing
ofrm.show

* Not for points *

The event is typically FormClosed():   (unless you're suing VB.Net 2003 or below)

I still have a problem to ge this work.
Problem is that there appears to be no "Close" event for Windows forms !?
I therefore tried the "Closed" keyword, but this doesn't work either.

As a test I established two forms (Form1 and Form2).
Form1 is MDI container. Both forms have one button control "Button1".

Form1 Code is:

Public Class Form1
    Dim ChildForm As New Form2
    Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
        Form2.Show()
    End Sub

    Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
        AddHandler ChildForm.Closed, AddressOf Childform_Terminated
    End Sub

    Private Sub Childform_Terminated()
        MsgBox("Return")
    End Sub
End Class

Form 2 code is:

Public Class Form2

    Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
        Me.Close()
    End Sub
End Class


What am I doing wrong ?

Something like:

Public Class Form1

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim f2 As New Form2
        f2.MdiParent = Me
        AddHandler f2.FormClosed, AddressOf Child_FormClosed
        f2.Show()
    End Sub

    Private Sub Child_FormClosed(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosedEventArgs)
        MessageBox.Show("Child form closed!")
    End Sub

End Class

Select all Open in new window

I am sorry but the event is still not firing (or captured) !

Public Class Form1

    Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
        Dim ChildForm As New Form2
        Form2.MdiParent = Me
        AddHandler ChildForm.FormClosed, AddressOf Childform_Terminated
        Form2.Show()
    End Sub

    Private Sub Childform_Terminated()
        MsgBox("Child form closed")
    End Sub

End Class
