EndEventHandler Delegate

Definition

Namespace:
System.Web
Assembly:
System.Web.dll

Represents the method that handles asynchronous events such as application events.

public delegate void EndEventHandler(IAsyncResult ^ ar);
public delegate void EndEventHandler(IAsyncResult ar);
type EndEventHandler = delegate of IAsyncResult -> unit
Public Delegate Sub EndEventHandler(ar As IAsyncResult)

Parameters

ar
IAsyncResult

The IAsyncResult that is the result of the BeginEventHandler operation.

Examples

The following code example uses the EndEventHandler delegate to register a handler for an asynchronous page.

<%@ page language="C#" Async="true"%>



  
    
      Page.AddOnPreRenderCompleteAsync Example
  
  
    

      
        Label 1

      
        Label 2

      
        Label 3

      
    
  


<%@ page language="VB" Async="true"%>



  
    
      Page.AddOnPreRenderCompleteAsync Example
  
  
    

      
        Label 1

      
        Label 2

      
        Label 3

Remarks

This delegate is called by the event source when completion of the asynchronous operation is signaled by a callback to the BeginEventHandler delegate.

When you create an EndEventHandler delegate, you identify the method that will handle the event. To associate the event with your event handler, add an instance of the delegate to the event. The event handler is called whenever the event occurs, unless you remove the delegate. For more information about event-handler delegates, see Handling and Raising Events.
