FocusedColumnChangedEventArgs is the data class for the following events:

• TreeList.FocusedColumnChanged

Remarks

The TreeList.FocusedColumnChanged event fires each time focus moves from cell to cell if the previously and currently focused cells belong to different columns. It also fires if none of the cells are focused. The FocusedColumnChangedEventArgs class allows you to obtain the column containing the focused cell via the inherited ColumnChangedEventArgs.Column property. The FocusedColumnChangedEventArgs.OldColumn property allows you to identify the column in which the previously focused cell resides.

Instances of the FocusedColumnChangedEventArgs class are automatically created, modified and passed to TreeList.FocusedColumnChanged event handlers.
