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

| OldColumn | Gets the previously focused column. |
Remarks
Write a FocusedColumnChanged event handler to perform specific actions each time focus has been moved from a column. There are two general cases in which this event fires:
- Focus is moved to another column. This takes place when end-users focus cells in other columns or change column order. Event is also raised when the same is performed via code.
- None of the columns is focused. This can take place when the focused column is deleted, nodes are added, etc.
This event handler receives a FocusedColumnChangedEventArgs parameter type. It allows you to determine previously and currently focused columns.
