as u can see username textbox inside login control..so cannot access property..how find control??

edit: mentioned in comments, want set login button clicked default button. need set button default button.

unfortunatelly, didn't format code asked in comment question. assume login button located in same name container username text box , name btnlogin , set control default control htmlform.defaultbutton property, so:

you use page.setfocus this. sets browser focus specified control:

page.setfocus(txtname);

if want reach username textbox, use just:

var login1 = loginview1.findcontrol("login1") login; if (login1 != null) {     var txtusername = login1.findcontrol("username");     if (txtusername != null)     {         page.setfocus(txtusername);     }      var btnlogin = login1.findcontrol("btnlogin");     if (btnlogin != null)      {          page.form.defaultbutton = btnlogin.uniqueid;     } }

but note:

for loginview control, when being added onto page, @ time, 1 template (anonymous or loggedin ) applied on control instance, @ time, can retrieve reference of controls in active template( can't access in non-active template).

so i've got simple form in canvas / iframe facebook app, , i'm trying pass along values post. reading on s.o. , fb's latest docs, understand it, data send via post form can accessed on receiving end $_request object. i read on thread on s.o. in order post forms work need pass along input named "signed_request" value current signed_request (i have signed request working ok otherwise...all login , authentication stuff working fine). isnt mentioned anywhere in official fb docs. so problem comes in $_request object signed request, , bunch of other session stuff. form inputs found. the way can read them set method of form "request" isn't real form method. takes of inputs , sends them args in url. horrible. here's sample page canvas app form i'm using try debug (leaving out authentication stuff): <form enctype="application/x-www-form-urlencoded" method="post" target="_top" id="my_form" action=...
