asp.net - Webmethod error with Jquery Ajax post function -

-

in asp.net 3.5 website, have jquery located in aspx page should execute function in code-behind. have used webmethod approach.

here error: system.argumentexception: unknown web method cloneitem. parameter name: methodname

here relevant code:

aspx page relevant part of jquery:

<%@ page language="vb" masterpagefile="~/pages/masterpage.master" title="planning" %> <%@ register tagprefix="pwc" namespace="pwc" %> <asp:content id="content1" contentplaceholderid="contentplaceholder1" runat="server"> <pwc:planning runat="server" skinfilename="core/planning.ascx" id="planning" secured="true"/>       $("#dialog-form").dialog({          autoopen: false,          height: 300,          width: 350,          modal: true,          buttons: {              "create clone": function () {                   var cloneitem = $('input[name=item]').is(":checked");                                  var intid = $(this).data('intid');                   var bvalid = true;                  bvalid = bvalid && checkselections();                   if (bvalid) {  $.ajax(        {         type: 'post',         url: 'planning.aspx/cloneitem',                                           data: "{'(intid': '" + $(this).data('intid') + "', 'item': '" + cloneitem + "'}" ,                   datatype: 'json',         contenttype: 'application/json; charset=utf-8'          // success: cloneonsuccess,         // error: cloneonerror           });        $(this).dialog("close");

function in planning.aspx vb code-behind:

imports system.web imports system.web.services <webmethod(enablesession:=true)> _  public shared function cloneitem(intid string, item boolean) string  'execute stored procedure here  return "success!" end function

master page has following scriptmanager:

  <ajaxtoolkit:toolkitscriptmanager id="scriptmanager1" runat="server" asyncpostbacktimeout="600" enablepartialrendering="true"  combinescripts="false" scriptmode="release" enablepagemethods="true" >     </ajaxtoolkit:toolkitscriptmanager>

any idea on doing wrong?

there 2 things might problem. first thing need code in web.config.

<system.web>   <httpmodules>     <add name="scriptmodule" type="system.web.handlers.scriptmodule,system.web.extensions, version=1.0.61025.0, culture=neutral, publickeytoken=31bf3856ad364e35"/>   </httpmodules> </system.web>

see reference : call asp.net pagemethod/webmethod jquery - returns whole page

another thing need use json.stringify in parameter while posting data.

see reference - http://www.asp.net/ajaxlibrary/jquery_webforms_retrieve_data_from_pagemethod.ashx

i used pyinstaller create standalone exe file pyqt project. did not use single file option because exe created single file option takes long open. therefore, pyinstaller created dist folder contains bunch of files including program.exe file. create setup.exe file place contents of dist folder in program directory , create shortcut in start menu , on desktop. want super simple user. maybe setup.exe files when download program cnet. found inno-setup, looks promising. however, not know if there special considerations because program standalone program create python/pyqt program. thanks! have experience task? there program using task not know about? inno-setup or nsis easiest use. tell them files include , put them , create nice installer you. wrote short tutorial on experiences using innosetup might find helpful: http://www.blog.pythonlibrary.org/2008/08/27/packaging-wxpymail-for-distribution/ note tutorial based around wxpython app wrote, concepts same.
