Event Data

The CopyingToClipboard event's data class is TreeListCopyingToClipboardEventArgs. The following properties provide information specific to this event:

Property	Description
Cells	Gets an array of cells whose values are about to be copied to the clipboard.
CopyHeader	Gets whether column headers are copied to the clipboard. Inherited from CopyingToClipboardEventArgsBase.
GridCells	Gets an array of cells whose values are about to be copied to the clipboard.
Handled	Gets or sets a value that indicates the present state of the event handling for a routed event as it travels the route. Inherited from RoutedEventArgs.
Nodes	Gets an array of nodes whose values are about to be copied to the clipboard.
OriginalSource	Gets the original reporting source as determined by pure hit testing, before any possible Source adjustment by a parent class. Inherited from RoutedEventArgs.
RoutedEvent	Gets or sets the RoutedEvent associated with this RoutedEventArgs instance. Inherited from RoutedEventArgs.
RowHandles	Gets an array of handles that correspond to rows whose values are to be copied to the clipboard. Inherited from CopyingToClipboardEventArgsBase.
Source	Gets or sets a reference to the object that raised the event. Inherited from RoutedEventArgs.

The event data class exposes the following methods:

Method	Description
InvokeEventHandler(Delegate, Object)	When overridden in a derived class, provides a way to invoke event handlers in a type-specific way, which can increase efficiency over the base implementation. Inherited from RoutedEventArgs.
OnSetSource(Object)	When overridden in a derived class, provides a notification callback entry point whenever the value of the Source property of an instance changes. Inherited from RoutedEventArgs.

Remarks

The TreeListControlBase provides two events that allow you to manually process clipboard operations.

• The CopyingToClipboard event is fired before node values are copied to the clipboard by an end-user, or in code. To cancel default processing, set the event parameter’s Handled property to true. This event is not fired if the DataControlBase.ClipboardCopyMode property is set to ClipboardCopyMode.None.
• The DataControlBase.PastingFromClipboard event is fired after an end-user has pressed Ctrl+V or Shift+Ins.
