    I have a page which calls a webmethod within a webservice and everything works fine. However, when I create a webmethod within the codebehind file for the page and I try to call it using PageMethods.SomeFunction() I get a javascript error on stating: PageMethods is undefined. What's going on? Am I possibly missing a line in my web.config file?

    Hi,

    protected void CalculateFundPercent()


    PageMethods must be exposed with the public access modifier.

    hi

    I am also getting the error "Microsoft JScript runtime error: 'PageMethods' is undefined".

    my code is following:

    [

    WebMethod]

    public int Add(int num1, int num2)

    {

    return num1 + num2;

    lblText.Text =

    "hi dost";

    }

    >>>>

    <

    form id="form1" runat="server">

    <

    atlas:ScriptManager ID="ScriptManager1" runat="server" />

    </form >

    <

    script type="text/javascript">

    function MyButtonClick()

    {alert("came");

    PageMethods.Add($("tb1").value, $("tb2").value, Add_Complete, Add_Timeout, Add_Error);

    }

    function Add_Complete()

    {

    if(arguments.length >0)

    $("result").innerText = arguments[0].toString();

    }

    function Add_Timeout()

    {

    alert("timeout");

    }

    function Add_Error(result, response)

    {

    alert("Error");

    // One of these 2 objects has the following methods (I forget which one):

    // get_statusText() gives error text

    // get_statusCode() gives error code

    }

    </

    script>

    please reply

    Hi Rupesh,

     

    did you find a solution for your problem, i do face the same strange behaviour. Is it just possible with a webservice?

    Hi,

    basically you're mixing two different approaches, so here's what I suggest:

    1. If you need to update some content on the page from server-side, use an UpdatePanel. I see that you're setting the text of a Label from a WebMethod; this is wrong because a WebMethod won't update the page content. The correct approach is to update the Label's text in the Click event (server-side) of button2.
    2. Use a WebMethod (or page method in this case) when you need to run almast all the page lifecycle (ViewState, events, not rendering) but you need only to return a value (or an object).
    3. Don't put javascript references or code in the <head /> section. If you put references, the files will be reloaded on each partial postback. If you put code, it could crash the UpdatePanel because it expects to find well formed XML. Better add js files through the ScriptManager control.
    4. Add the attribute type="text/javascript" to the script tag when declaring js code. The Atlas framework might need it in some cases.
    5. Protect the javascript code in CDATA or comment sections.

    i was getting the same error message,

    my fault was that i was using a usercontrol, and the PageMethod needs to be declared on the PAGE, not on the usercontrol used in the page

    I believe you need EnablePageMethods="true" on your ScriptManager.

     also page methods needs to be static in code behind

     [WebMethod]

    public static bool foo
