PageMethod in the codebehind

I have a method in my codebehind that I would like to call from javascript. My script manager tag has EnablePageMethods="true" and the method in my codebehind is tagged with [WebMethod] and [ScriptMethod]. When I trigger the javascript, I get errors. I've found some things that say that if you want to call a server side method (not in a web service) from your javascript with the PageMethods collection, you have to have that in a script block in your aspx. I've created a script block with a method in my aspx that just calls the function in my codebehind, but I think that's kind of ugly. Is there something I might have just missed that would allow me to just call my codebehind?

Thanks

Here's a code example: http://encosia.com/index.php/2007/07/11/why-aspnet-ajax-updatepanels-are-dangerous/

Your pagemethod has to be public and static. If that doesn't help, try posting some sample code for us to help debug.

Thanks. That's what I was trying and it didn't work for me. I found some posts around that said that if you wanted to do this, the server side method you were calling had to be in the ASPX. Seemed to fit because of the errors I was getting and the fact that putting a wrapper function in my ASPX for the actual method I wanted to call worked. However, I gave it one more shot this morning (same exact code that didn't work before, I swear) and it's gold.

pagerequest manager events seems to be raised to many times by the browser

Hello,

I have the next issue in my web application.

On server i'm sending to the client during a server event with registerdataitem a string -an url.

On client in pageloading i'm getting the url and showing into a popup window. This is the code:

var

wind=null;

var

currenturl=null;

var

i=0;

Sys.Application.add_load(ApplicationLoadHandler);

function

ApplicationLoadHandler(sender, args)

{

//Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler);

Sys.WebForms.PageRequestManager.getInstance().add_pageLoading(pageLoadingHandler)

}

//function EndRequestHandler(sender, args)

function

pageLoadingHandler(sender, args)

{

var dataItems = args.get_dataItems();

wind=document.getElementById(

'popupid');if (wind!=null)return;if (document.title.indexOf("Print")>=0)

currenturl=dataItems[

'ctl00_currenturl'];else

currenturl=dataItems[

'currenturl']if (currenturl !=null )//show the popup

{

wind=window.open(currenturl,

'popupid');

//DeleteFile(dataItems['currenturl']);works fine only on ie this solution

}

}

The problem is that the ajax pagerequestmanager event is raised too many times making the popup to be created to many time and sometimes browser to run out of resources.

How could i fix it i mean the pagerequestmanager event to be raised normaly i mean once.

I 'm using ie 6.5

Thanks

Hi,

Please use try this code snippet:

Sys.Application.add_load(ApplicationLoadHandler)

function ApplicationLoadHandler(sender, args)
{
var prm = Sys.WebForms.PageRequestManager.getInstance();
if (!prm.get_isInAsyncPostBack())
{
prm.add_pageLoading(pageLoadingHandler);
}
}

Hope this helps.
