How to call postback using javascript on ASP.NET form -

i have web form textbox , button. want after "enter" key click on textbox postbak form.

i using next code:

onkeypress=" if(event.keycode==13)  { alert(2); webform_dopostbackwithoptions(new webform_postbackoptions('ctl00$contentplaceholder1$btnsearch', '', true, '', '', false, false)); alert(2);  return false;}

i 2 alerts, postback doesnot happen.

any ideas wrong?

asp.net creates client side javascript method __dopostback support postback.

example: __dopostback('__page', 'mycustomargument');
