| Property | Description |

| Cancel | Gets or sets a value indicating whether the event should be canceled. Inherited from CancelEventArgs. |

Remarks
The ColumnsRemoving event allows you to perform any actions before columns are deleted from a worksheet. To prevent columns from being deleted, set the event parameter’s Cancel property to true.
After columns have been removed from a worksheet, the Workbook.ColumnsRemoved event is raised.
Note
By default, the ColumnsRemoving event does not occur when removing columns in code. However, this event will also be triggered by changes made via an API if you set the WorkbookEventOptions.RaiseOnModificationsViaAPI property (accessible via the Workbook.Options.Events.RaiseOnModificationsViaAPI notation) to true.
