IReadOnlyCapable

• Adjustable colors in disabled state (see DisabledBackColor and DisabledForeColor).
• TextChangedOnLeave event: occurs when leaving the control and Text is different from the value when the control received focus.
• Auto complete works even in Simple mode.
• Consistent font scaling on all platforms when per-monitor DPI awareness is enabled (see AutoScaleFont). Note that it affects font scaling only, so auto-sizing behavior still depends on the current platform.

The following image illustrates a few features of the AdvancedComboBox class, like the default disabled colors difference (the disabled colors are customizable), and the ReadOnly mode, which is not supported by a regular ComboBox:
