Fires after the AppMenuFileLabel.Checked property has been changed.
[DXCategory("Events")] public event EventHandler CheckedChanged
<DXCategory("Events")> Public Event CheckedChanged As EventHandler
The CheckedChanged event's data class is EventArgs.
The CheckedChanged event fires after the AppMenuFileLabel.Checked property's value has been changed. For instance, this happens when an end-user clicks a check button displayed at the label's right edge (see AppMenuFileLabel.ShowCheckButton). You can prevent the check state from being changed on clicking this button by handling the AppMenuFileLabel.LabelImageClick event and setting the event's Cancel parameter to true.
