public event EventHandler<ClipboardCopyingEventArgs> ClipboardCopying
Event Data

The event handler receives an argument of type ClipboardCopyingEventArgs containing data related to this event. The following ClipboardCopyingEventArgs properties provide information specific to this event.

PropertyDescription
Cancel (Inherited from Infragistics.Windows.Controls.Events.CancelableRoutedEventArgs) 
FieldCount (Inherited from Infragistics.Windows.DataPresenter.Events.ClipboardOperationEventArgs)Returns the number of fields represented in the collection.
Handled (Inherited from System.Windows.RoutedEventArgs)Gets or sets a value that indicates the present state of the event handling for a routed event as it travels the route.
OriginalSource (Inherited from System.Windows.RoutedEventArgs)Gets the original reporting source as determined by pure hit testing, before any possible System.Windows.RoutedEventArgs.Source adjustment by a parent class.
RecordCount (Inherited from Infragistics.Windows.DataPresenter.Events.ClipboardOperationEventArgs)Returns the number of records represented in the collection.
RoutedEvent (Inherited from System.Windows.RoutedEventArgs)Gets or sets the System.Windows.RoutedEventArgs.RoutedEvent associated with this System.Windows.RoutedEventArgs instance.
Source (Inherited from System.Windows.RoutedEventArgs)Gets or sets a reference to the object that raised the event.
Values (Inherited from Infragistics.Windows.DataPresenter.Events.ClipboardOperationEventArgs)Returns a collection of the unconverted values to be used as the source for the clipboard operation.
Remarks

This event can be used to provide the formatted values that will be placed on the clipboard.

Example
The following sample demonstrates how to use the ClipboardCopying event to provide a custom formatted version of the value that should be used in the output put into the clipboard.
