How to fire a non static code behind method from a javascript postback

I have found an interesting way of firing code behind methods from javascript functions without creating static web methods and ajax calls.

This in conjunction with an UpdatePanel produces a method that can be called from javascript that does not refresh the page.

If an update panel is used, then its a good idea to use the Id for a control inside the update panel so its marked for asyncrous postback, then differentiate between methods using the event argmument

to post back to the server using a javascript function the following code can be used:



We can then set the code behind to inspect the Request.Form collection for any postback information.

This can be very powerful as potentially any code behind method can be called!
