ASP.NET 2.0 has async pages and async tasks. These will postpone rendering until the async methods you are calling are returned. Async Pages is for one asynchrounous call. Async Tasks can coordinate multiple calls.
Look up AddOnPreRenderCompleteAsync for more on Async page. And PageAsyncTask for async tasks. -----Original Message----- From: Discussion of advanced .NET topics.

I have the following piece of code that is in the code behind of a user control in an eventhandler ReloadCart(); OrderCalculatedHandler resultHandler = new OrderCalculatedHandler(ResultHandler); _msmqAdapter.CalculateOrder(_cart, resultHandler); Profile.ShoppingCart = _cart; RetrieveOrderFromProfile(); The line _msmqAdapter.CalculateOrder(_cart, resultHandler); is the line that calls the asynchronous method. resultHandler is function pointer to the following piece of code: private void ResultHandler(object sender, MSMQEventArguments<ShoppingCart> e) { _cart = e.Result; Profile.ShoppingCart = _cart; } The problem being that the method takes a long time to run and the page finishes processing before an event is raised back to the page. What can I do to tell the page to wait for the ResultHandler method to execute?
