' unless that tab has overriden the setting by having a non-default AllowClosing.
Me.UltraTabControl1.AllowTabClosing = False

' The close button in all tabs should come before the image and text of the tab 
' unless that tab has overriden the setting by having a non-default CloseButtonAlignment.

' unless that tab has overriden the setting by having a non-default CloseButtonVisibility.
' For the close button to show when the tab is hot tracked, UseHotTracking must be True.
Me.UltraTabControl1.TabCloseButtonVisibility = TabCloseButtonVisibility.WhenSelectedOrHotTracked
Me.UltraTabControl1.UseHotTracking = DefaultableBoolean.True
using System.Windows.Forms;
