Help: how to create handler to the button click event

Handle Button Click

Process Button Clicks

OnAction property of the Button object assigns VBA procedure to the button object.

When you press button, xlCompiler calls this routine.

With .AddButton
	.Image = "Calendar"
	.ImageDisabled = "CalendarDisabled"
	.OnAction = "ShowRegPaymentCalendar"
	.Tooltip = "Payments Calendar"
End With 

Sub ShowRegPaymentCalendar()
	' do somtehing
End Sub

OnAction property is used by all ribbon controls.

When selection in the Combobox is changed - routine defined by OnAction button is called.
