Hello Fabio,

Thank you for the question.

RadDock does not expose the active MDI child form as a property. However, you can easily get the active form by using the following code snippet:

Dim activeForm As Form = Nothing
Dim mdiChild As Form = Me.FindForm().ActiveMdiChild
Dim window As DockWindow = Me.radDock1.DocumentManager.ActiveDocument
If TypeOf window Is HostWindow Then
    Dim host As HostWindow = TryCast(window, HostWindow)
    If Not host Is Nothing Then
        If TypeOf host.Content Is Form Then
            ' this is the form in question
            activeForm = CType(host.Content, Form)
        End If
    End If
End If

If I understand your second correctly, the HostWindow that hosts a child mdi form is automatically closed when the form is closed, so you do not need to do it manually.

If you have additional questions, feel free to contact me.
