I have to build a custom control where I will render a textbox where I am supposed to take input, and on textbox change event I will have to keep a list of objects that satisfy that search string I took from the input, which should be exposed to be fetched at any time. I have no idea how to make an asynchronous call to the code behind the control. I am very new to custom controls, recently I have developed only one that rendered some div. I am very confused about this one, can any one give me any idea of how to do this? I am not asking for the code, I can figure it on my own, but I am missing the idea or general knowledge about asp custom controls.

It's simple you need to add some js to the control you rendering, that will do what you need to do async, if you need any code examples I will gladly post it, after I get back home. – hackp0int Mar 05 '13 at 16:46

I really need some examples. I tried rendering a couple of controls inside an updatepanel, with thier events bound, but none of them fire. Infact, on button clicks it is posting back which is weird as i put them in an updatepanel. – Taha Rehman Siddiqui Mar 06 '13 at 05:38

OK couple of things, button will fire an event because it's behavior on with in the 'form' it's causes a submit. What you need to do is, to attach an attribute [autopostback=true] – hackp0int Mar 06 '13 at 05:41
