Asynchronous call

Question

Hi All I am performing some database operation using Asynchronous call in web application. My question is -- Is it necessary to Register the async task on page using Page.RegisterAsyncTask(new PageAsyncTask( new System.Web.BeginEventHandler(this.BeginMethod) new System.Web.EndEventHandler(this.EndMethod) new System.Web.EndEventHandler(this.GetTimeout) null true)); method ??? Can't I do it in another way by 1. not using Page.RegisterAsyncTask 2. Declaring a delegate and using BeginInvoke and EndEnvoke method ??? Pls suggest... Thanks in advance :-)

I propose two ways As you say create a delegate that points on your method and as you know the delegate are thread safe type first create a delegate then target the given method then use beginInvoke() and you can even ignore the EndInvoke method as the targeted method is void Or declare a tread and then a threadstart delegate that points the targeted method then pass the threadstart as a argument to the thread instance finally use the Start() method of the Thread instance

I'm pretty sure you have to register the event with the page because of the stateless nature of http.
