Occurs before the control’s data recalculation starts.
public event RoutedEventHandler BeginRefresh
Public Event BeginRefresh As RoutedEventHandler
The BeginRefresh event's data class is RoutedEventArgs. The following properties provide information specific to this event:
|Handled||Gets or sets a value that indicates the present state of the event handling for a routed event as it travels the route.|
|OriginalSource||Gets the original reporting source as determined by pure hit testing, before any possible Source adjustment by a parent class.|
|RoutedEvent||Gets or sets the RoutedEvent associated with this RoutedEventArgs instance.|
|Source||Gets or sets a reference to the object that raised the event.|
The event data class exposes the following methods:
|InvokeEventHandler(Delegate, Object)||When overridden in a derived class, provides a way to invoke event handlers in a type-specific way, which can increase efficiency over the base implementation.|
|OnSetSource(Object)||When overridden in a derived class, provides a notification callback entry point whenever the value of the Source property of an instance changes.|
The PivotGridControl.BeginRefresh and PivotGridControl.EndRefresh events serve as notifications for operations on data (for instance, sorting and grouping data). The PivotGridControl.BeginRefresh event fires before an operation starts, and the PivotGridControl.EndRefresh fires after the operation has been completed.
The BeginRefresh event is not raised in asynchronous mode (if the PivotGridControl.UseAsyncMode property is true). For async mode, handle the PivotGridControl.AsyncOperationStarting event that occurs before an asynchronous operation is started.
