Event Data

The PanesUnfrozen event's data class is PanesUnfrozenEventArgs.


Handle the PanesUnfrozen event to perform specific actions when an end-user unlocks frozen rows and columns on a worksheet via the control’s UI. After a worksheet area has been frozen, the SpreadsheetControl.PanesFrozen event is raised.


By default, the PanesUnfrozen event does not occur when unfreezing rows and 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.
