Does IIS have to be configured to run WebMethods?

Question

I have this code:

<script type="text/javascript">
window.onbeforeunload = function (e) {
PageMethods.LogOutOfRecord();
};
</script>

[WebMethod(EnableSession = true)]
public static void LogOutOfRecord()
{
ApplicantEntryEdit aee = new ApplicantEntryEdit();
aee.LoggingOutOfInvestigation();
}

This code works great locally in Visual Studio. However the WebMethod does not get hit on IIS on testing server.

Thanks in advance!

To use PageMethods, you will need to make sure that you have enabled the following:

1. EnableSession attribute on the WebMethod
2. ScriptManager control on the page
3. EnablePageMethods property on the ScriptManager control

Here's an example of how you can set this up:

<asp:ScriptManager runat="server" EnablePageMethods="true" />  
  
[WebMethod(EnableSession = true)]  
public static void LogOutOfRecord()  
{  
    ApplicantEntryEdit aee = new ApplicantEntryEdit();  
    aee.LoggingOutOfInvestigation();  
}  
  

Additionally, make sure that the WebMethod is being called from the correct URL. You can check this by inspecting the network traffic in your browser's developer tools and seeing if the WebMethod is being called and if it is returning a response.

You can try removing router settings in web.config and adding to httpmodules section.

<add name="ScriptModule" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>

The below code works on the server.

The above code does not.

This was the issue.

window.addEventListener('beforeunload', (event) => { PageMethods.LogOutOfRecord(); });

I do not have an explanation as to why the original code will work locally and not on the server and this one will work on both.
