The CopyToClipboard method copies selected nodes to the Clipboard. The way data is copied to the Clipboard is affected by the following options:
If the TreeListOptionsClipboard.AllowCopy property is enabled, an end-user can copy selected nodes to the Clipboard via the CTRL+C shortcut.
Multiple node selection can be enabled via the TreeListOptionsSelection.MultiSelect property. All selected nodes can be accessed via the Selection property.
