Called before an event is bubbled to its parent.

protected override System.Threading.Tasks.Task<bool> OnPreBubbleEventAsync (Microsoft.Bot.Builder.Dialogs.DialogContext dc, Microsoft.Bot.Builder.Dialogs.DialogEvent e, System.Threading.CancellationToken cancellationToken);

override this.OnPreBubbleEventAsync : Microsoft.Bot.Builder.Dialogs.DialogContext * Microsoft.Bot.Builder.Dialogs.DialogEvent * System.Threading.CancellationToken -> System.Threading.Tasks.Task<bool>

Protected Overrides Function OnPreBubbleEventAsync (dc As DialogContext, e As DialogEvent, cancellationToken As CancellationToken) As Task(Of Boolean)

Parameters

dc: DialogContext

The dialog context for the current turn of conversation.

e: DialogEvent

The event being raised.

cancellationToken: CancellationToken

Cancellation token.

Returns

Task<Boolean>

Whether the event is handled by the current dialog and further processing should stop.

Remarks

This is a good place to perform interception of an event as returning `true` will prevent any further bubbling of the event to the dialogs parents and will also prevent any child dialogs from performing their default processing.
