This event fires before the RowSel and ColSel properties change, either as a result of user actions or through code. It allows you to prevent the selection of certain cells, thus creating "protected" ranges on a grid.
To prevent the selection of a range, you also need to handle the BeforeRowColChange event, which is fired before the Row and Col properties change.
