Have multiple ComboBox's use the same event

I have roughly 140 ComboBox on a form. When some selects a new item within one of the box's I would like to highlight that box.

I would like to use the SelectionChangeCommitted event and I would use the following code:

Private Sub cmbDesk1_SelectionChangeCommitted(sender As System.Object, e As System.EventArgs) Handles cmbDesk1.SelectionChangeCommitted
 Dim tbControl As ComboBox = DirectCast(sender, ComboBox)
 tbControl.BackColor = Drawing.Color.Red
 tabFloor1.Focus()

I know that I can add extra lines after the "Handles" section of the subroutine declaration but it there a neat way of doing it without adding every ComboBox to it? Something similar to 

Me.TabPage1.Controls.OfType(Of ComboBox)()

Kind regards

Matt

You can always loop all combobox and AddHandler yourself.

For Each cb As ComboBox In Me.TabPage1.Controls.OfType(Of ComboBox)()
    AddHandler cb.SelectionChangeCommitted, AddressOf cmbDesk1_SelectionChangeCommitted
Next

This should be done once.
