answer:
i have removed _dopostback() added me , instead added on page_load() adds _dopostback() if there no asp.net controls requires method.

i've had similar problem, when trying popup dialog confirming record deletion. code i've used (jquery ui dialog) , works perfectly. don't add new dopostback. instead, try follow idea. can adapt fit requirements:
// when user tries delete record, show confirmation. $(".confirmationbutton").click(function(e) { // stop postback e.preventdefault(); $(".confirmationdialog").dialog("open"); }); $(".confirmationdialog").dialog({ buttons: { "no": function() { $(this).dialog("close"); }, "yes": function() { $(this).dialog("close"); // user confirmed deletion, carry on postback. eval($("#ctl00_maincontentplaceholder_hdnbtnpostback").val()); } } }); somewhere on code (when checking page source), you'll find this:
<input id="ctl00_maincontentplaceholder_hdnbtnpostback" type="hidden" value="__dopostback('ctl00$maincontentplaceholder$btndelete','')" name="ctl00$maincontentplaceholder$hdnbtnpostback"> that's object using eval().
