protected internal override bool HasTriggered ()
Protected Friend Overrides Function HasTriggered As Boolean
virtual bool HasTriggered () override
true if the trigger was activated; otherwise, false.
Control developers can override the HasTriggered() property to provide custom logic for determining whether the trigger was activated. To see your custom trigger appear at design time in the <Triggers> element of the UpdatePanel control, you can add an @ Register directive on the page or in the controls Element for pages (ASP.NET Settings Schema) section of the Web.config file.
