Occurs when the value of the ToolStripItem.BackColor property changes.
This event is raised if the ToolStripItem.BackColor property is changed by either a programmatic modification or user interaction.
Changing the Control.Enabled property of a System.Windows.Forms.ToolStrip does not raise the ToolStripItem.BackColorChanged event. Raise this event with specific property settings.
