Remarks
The list box control enables you to custom paint its items. Handle the DrawListBoxItem event to override default item painting. This event is raised each time an item is about to be painted. The event parameter’s properties allow you to define the object used to paint the item’s boundaries, style and the index of the item. To get the item’s state (selected, checked, grayed, inactive, etc) and the value of the item being drawn, use the ListBoxDrawItemEventArgs.State and ListBoxDrawItemEventArgs.Item properties respectively.
Important
You must set the ListBoxDrawItemEventArgs.Handled property to true to override the default painting.
