you could use jquery onchange method:

ref: http://www.w3schools.com/jquery/event_change.asp
The code could be something like:

$("textbox").change(function(){
   this.form.submit();
});

Open in new window

If(this.val() === 'A'){
   this.form.submit();
}
});

You have to make sure to replace $("textbox") with ("#idofthetextbox") and if this.form.submit() doesn't work then replace that with ("#idofsubmitbutton").click();

You want to call js key press from the server side code? That beats all logic :)

I would suggest that you read about what server side code is and what client side js is. If you are already processing in server side why not do all your processing in server side and then send what the browser needs to see. If by server side you mean an ajax call that is being processed in server then i should suggest that you ask the question better .

Yes, you can call a method in server side from js. They are known as ajax calls. If you are using jquery then read about ajax get or ajax post.
