i have tried doing this. doesn't work

 protected void page_load(object sender, eventargs e)         {             tbps.text = " ";             tbname.text = " ";             tbemail.text = " ";             tbcontact.text = " ";             tbsug.text = " ";             rbtheme3.checked = true;             rbfoodvar3.checked = true;             rbtransport3.checked = true;             rbloc3.checked = true;             rbtime3.checked = true;         } 

do in javascript inside unload function

for textboxes

$('input:text').val(''); 

for checkboxes

$('input:checkbox').prop('checked', false); 

for radioboxes

var radiogroups = [];  $("input:radio").each(function(){     if (radiogroups.indexof(this.name) > -1) { return; }     radiogroups.push(this.name); });  radiogroups.foreach(function (groupname) {    var $group = $('input[name="' + groupname + '"]:radio');    $group.prop('checked', false);    // if want select third 1    $group[2] && $($group[2]).prop('checked', true); });
