Public Event ColumnsRemoving As ColumnsChangingEventHandler
The ColumnsRemoving event's data class is ColumnsChangingEventArgs. The following properties provide information specific to this event:
| Property | Description |
|---|---|
| Cancel | Gets or sets a value indicating whether the event should be canceled. Inherited from CancelEventArgs. |
| Count | Gets the number of rows/columns that will be inserted or removed. Inherited from RowsColumnsChangingEventArgsBase. |
| StartIndex | Gets the index of the first row/column after which rows/columns will be inserted or removed. Inherited from RowsColumnsChangingEventArgsBase. |
The ColumnsRemoving event allows you to perform any actions before an end-user removes columns from a worksheet using the control’s UI. To prevent columns from being deleted, set the event parameter’s Cancel property to true.
After columns have been removed from a worksheet, the SpreadsheetControl.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 SpreadsheetControl.Options.Events.RaiseOnModificationsViaAPI notation) to true.
