Represents a method that will handle the TreeList.CustomDrawFooterCell event.
NuGet Package: DevExpress.Win.TreeList
The event sender (typically the TreeList control).
A CustomDrawFooterCellEventArgs that contains data related to the event.
When you create a CustomDrawFooterCellEventHandler delegate, you identify the method that will handle the event. To associate the event with your event handler, add an instance of the delegate to the event. The event handler is called whenever the event occurs, unless you remove the delegate.
