Raises the Sorting event.

The event data.
Exceptions
The ListView control is not bound to a data source control by using the DataSourceID property.
Remarks
The Sorting event is raised when a Sort button is clicked or the Sort method is called, but before the ListView control handles the sort operation. (A Sort button is a button control whose CommandName property is set to "Sort".) This enables you to perform a custom routine whenever this event occurs, such as canceling the sorting operation.
Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.
The OnSorting method also enables derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.
Notes to Inheritors
When you override OnSorting(ListViewSortEventArgs) in a derived class, call the base class's OnSorting(ListViewSortEventArgs) method so that registered delegates receive the event.
