The event handler receives an argument of type RangeEventArgs containing data related to this event. The following RangeEventArgs properties provide information specific to this event.
Property | Description |
---|---|
Cancel | Gets or sets a value indicating whether the new selection should be canceled. |
NewRange | Gets the range that will be selected after the event. |
OldRange | Gets the range selected before the event. |
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 C1FlexGridBase.BeforeRowColChange event, which is fired before the Row and Col properties change.
