c# - PAGEMETHODS is not working from JS function

I am trying to call code behind method from JS function using pagemethods but its not calling and its not throwing any error either...

function example(){

pagemethods.method();
}

**aspx.cs
[webmethod]
public static void method(){

//some logic
}

so to find the issue i did some negative testing for that

I mented WEBMETHOD then it showed an error by saying"object does not support this property or method".can i assume this case shows pagemethods is working!!!
Then I replaced calling method name in JS function to pagemethods.newmethod() but i didn't change method name to newmethod..i was expecting an some error but it didn't give me an error..

NOTE:i have "method=post" in form declaration..does it effect pagemethods anything..

so confused why this issue is happening!!!

can we call codebehind method in any other way instead of pagemethods..please advice!!!

why you think that its not calling? – Grundy Commented Jan 19, 2014 at 16:32
try see sample Calling Static Methods in an ASP.NET Web Page – Grundy Commented Jan 19, 2014 at 16:50
i am debugging code with breakpoints so i dont see that static method got invoked which ever am calling using pagemethods.i am using same concept that got mentioned in "Calling Static Methods in an ASP.NET Web Page" – user3212507 Commented Jan 20, 2014 at 17:17
can you provide your markup? – Grundy Commented Jan 20, 2014 at 17:19

Sorted by: Reset to default 3

in msnd you can see a sample of this, so you need...

in markup:

<asp:ScriptManager ID="sm" runat="server" EnablePageMethods="true">
    <Scripts >
        <asp:ScriptReference Path="pm.js" />
    </Scripts>
</asp:ScriptManager>

in code behind: your static method, with attribute [WebMethod]

in pm.js: something like this

function example(){
    PageMethods.method();
}

UPDATE
Another variant is use an ajax request to your method, for example with jquery in goes like this:

function CallMethod(){
    $.ajax({
        type: "POST",
        dataType: 'json',
        contentType: "application/json; charset=utf-8",
        url: "YourPage.aspx/yourmathod",
        data:JSON.stringify({}), // parameters for method
        success: function (dt) { alert(dt);}, //all Ok
        error: function () { alert('error'); } // some error
    });
}

Perhaps you might be missing EnablePageMethods = true in your aspx page...

This approach is also working -

Below given code worked for me.

using Newtonsoft.Json;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

public partial class Default2 : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {

    }

    [System.Web.Services.WebMethod(EnableSession = true)] 
    [System.Web.Script.Services.ScriptMethod(UseHttpGet = false, ResponseFormat = System.Web.Script.Services.ResponseFormat.Json)]
    public static string yourmethod1()
    {
         return "Allow user";
    }
}
