DataObjectCopyingEventHandler

A delegate that references the handler method to add.

Remarks

The Copying event occurs when a copy operation has finished converting the selected content into all specified data formats, has stored all data formats in the associated data object, and is ready to put the data object on the system Clipboard or to begin a drag operation.

Use this event to inspect or modify a data object after a copy operation completes, and before proceeding with subsequent operations. The entire copy operation can be canceled by calling CancelCommand.
