Event Data

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

Property	Description
Column	Gets a Tree List column. Inherited from ColumnChangedEventArgs.
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.
