ColumnChangedEventArgs is the data class for the following events:

• TreeList.ColumnChanged
• TreeList.ColumnUnboundExpressionChanged
• TreeList.ColumnWidthChanged

Remarks

The TreeList.ColumnChanged event occurs immediately after the column collection or an individual column has been modified. ColumnChangedEventArgs class instances provide data for this event. You can use their ColumnChangedEventArgs.Column property to determine the column that has been added, moved or modified.

ColumnChangedEventArgs objects with proper settings are automatically created and passed to handlers of the TreeList.ColumnChanged event.
