This event fires before the C1.Win.C1FlexGrid.C1FlexGridBase.Row or C1.Win.C1FlexGrid.C1FlexGridBase.Col 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.
C1.Win.C1FlexGrid.C1FlexGridBase.BeforeRowColChange fires only when the C1.Win.C1FlexGrid.C1FlexGridBase.Row or C1.Win.C1FlexGrid.C1FlexGridBase.Col properties are about to change. To detect extended selections, you also need to handle the C1.Win.C1FlexGrid.C1FlexGridBase.BeforeSelChange event.
