Asynchronous Client Script support Control for ASP.NET V2.0
I have created and made available a control aimed at ASP.NET V2.0 (developed with Beta2) that simplifies the use of Asycnronous client script callbacks in ASP.NET V2.0. Currently, setting up async client scripting in ASP.NET V2.0 requires some fiddly server side code to get a callback event reference, wrap it in a function script, and register it.
This control takes care of all that for you. Simply drop it on your webform page, specify the client callback method and the client side error method (which you must supply in your webform) as well as supply a javascript method name which the control will register that initiates the callback action.
The Server side functionality is exposed via a standard event handler, so you can simply double click on the 'ServerSideCallback' event on the control and type the code that will be responsible for getting called asynchronously by the client script.
It also support an interval timer, so that you can specify an interval in milliseconds, and the control will setup a repeating timer to initiate the asynchronous client script call every the interval elapses.
You can grab the control from my website or from my repository on the Project Distributor site. Full source code and an example project (although trivial) is supplied.
If you find it useful, I'd love to hear some feedback.
