When CellClickAction is set to 'EditCell', clicking onto a cell activates the cell and immediately enters edit mode on the cell. Setting the property to 'EditCellSelectText' results in the same behavior as 'EditCell' except that the contents of the cell are selected after edit mode is entered. When set to 'ActivateCell', the cell is activated but not automatically placed into edit mode. When set to 'SelectNodeOnly', no cell is activated or placed into edit mode, but rather the node is activated and optionally selected (depending on the value of the SelectionType property).
Note: The CellClickAction property is only applicable to nodes which display columns; nodes that do not display cells behave as if the property were set to 'SelectNode'
Also note that the CellClickAction property applies exclusively to mouse activity, and does not prevent the end user from accomplishing the same result by using the keyboard. For example, when CellClickAction is set to 'ActivateOnly', entering edit mode via the keyboard is not disallowed; edit mode can still be entered by pressing F2.
