Fire Textbox.TextChange event without a button click
<p>I want to call Textbox.OnTextChange event without having to click a submit button or any button.  How can I do this?  As I enter text in the textbox, I want the ontextchange event to fire.</p>

<p>I would elaborate this further.I've a function for validating my entry in textbox which I'm calling ontextchange property.Now this function should be called without me changing focus from my textbox.</p>
