  I have also tried emiiting the <input> tag exactly the ASP.NET emits a server radio button as. And now clicking the radio button does post back to the server, BUT, it does not activate the "CheckedChanged" event, which is quite obvious . But then what is the workaround if I want to raise that event too ?

    Thanks Bipin.

    But i also want to handle events on radio button like "CheckedChanged" [in radiobutton server control]. Basically I need to perform some task ON SERVER side when someone selects a radio button.
    How can I do that if I emit <input> tags ?
