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

Property Description
Cancel Gets or sets whether the current operation needs to be canceled.

The ClipboardNodePasting event fires before a node is pasted to the control from the clipboard. If the clipboard contains multiple nodes, the event fires for each node. The event allows you to modify data or to cancel pasting the processed row.

A node is not pasted to the control if any of its columns cannot accept data being pasted. For example, if data types do not match. You can set the PasteMode event argument to Force to forcibly paste the node.

To check if a particular value or the entire node is valid, use the IsValueValid and IsNodeValid methods.
