Event Data

The OlapException event's data class is PivotOlapExceptionEventArgs. The following properties provide information specific to this event:

Property	Description
ErrorPanelText	Gets or sets a text from the error panel. Inherited from PivotQueryExceptionEventArgs.
Exception	Gets the exception that was thrown. Inherited from PivotQueryExceptionEventArgs.
Handled	Gets or sets a value that indicates the present state of the event handling for a routed event as it travels the route. Inherited from RoutedEventArgs.
IsDrillDownRequested	Gets a value that indicates whether a query processing error occurs during a drill-down request. Inherited from PivotQueryExceptionEventArgs.
OriginalSource	Gets the original reporting source as determined by pure hit testing, before any possible Source adjustment by a parent class. Inherited from RoutedEventArgs.
RoutedEvent	Gets or sets the RoutedEvent associated with this RoutedEventArgs instance. Inherited from RoutedEventArgs.
ShowErrorPanel	Gets or sets whether to show the error panel. Inherited from PivotQueryExceptionEventArgs.
Source	Gets or sets a reference to the object that raised the event. Inherited from RoutedEventArgs.

The event data class exposes the following methods:

Method	Description
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. Inherited from RoutedEventArgs.
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. Inherited from RoutedEventArgs.

Remarks

Use the event parameter’s PivotQueryExceptionEventArgs.Exception property to determine which exception has been thrown.

To cancel the default exception handling actions, set the Handled property to true.
