ASPxClientTreeList.ClipboardCellPasting Event

Occurs before a cell is pasted to the control from the clipboard. Allows you to update the pasted data or skip a cell.

Declaration

ClipboardCellPasting: ASPxClientEvent<ASPxClientTreeListClipboardCellPastingEventHandler<ASPxClientTreeList>>

Event Data

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

Property	Description
cancel	Specifies whether to cancel the related action (for example, row edit, export). Inherited from ASPxClientCancelEventArgs.
cellInfo	Obtains information about the processed cell.
newText	Gets the new text of the processed cell.
newValue	Specifies the new value of the processed cell.
oldText	Gets the old text of the processed cell.
oldValue	Obtains the old value of the cell.

Remarks

The ClipboardCellPasting event fires before a cell is pasted to the control from the clipboard. If the clipboard contains multiple cells (EnableMultipleCellSelection), the event fires for each cell. The event allows you to modify data or to cancel pasting the processed cell.

The control does not paste cells if the required column cannot accept the pasted data (for example, if data types do not match).

The following example illustrates how to modify data before pasting to the control in the ClipboardCellPasting event handler:
