I having the following issue. I have a main form (MDI Parent) set up with the Elegant Ribbon and three MDI Children. On the Elegant Ribbon, I have one button to clear any contents of the TextBox component. On one MDI Child, I have a Elegant Ribbon TextBox component. When I click the button, it does nothing. The content in the TextBox still remains.

Now, I wanted to check if the MDI Child is active or not. But this does not work either.

Private Sub btnNew_Click(sender As Object, e As EventArgs) Handles btnNew.Click
Dim NewMDIChild As New frmCLA()
Dim activeChild As Form = Me.ActiveMdiChild

If (Not activechild Is Nothing) Then
MsgBox("No active MDI Child", MsgBoxStyle.Exclamation)
MsgBox("Active MDI Child: " & NewMDIChild.Name, MsgBoxStyle.Information)
End If
End Sub

The source code shows whether or not the MDI Child is active and it gives constantly "No active MDI Child".

What am I doing wrong or missing?
