Atlas web service proxy undefined - bug or mistake?

Ok, here's the deal: I have javascript method that is called on the window's load event:

window.onload = function () { getDataForTable();};

Pretty striaghtforward, right? Well, when the getDataForTable method executes it calls an Atlas proxy method:

WebServices.Callbacks.CalendarFunctions.CheckDate(dateField.value, getDataForTable_Callback);

But when the script execute on load, I get an error stating that 'WebServices' is not defined. When I check the HTML output the Atlas javascript reference is there: "text/xml-script">"http://schemas.microsoft.com/xml-script/2005"> <references> <add src="http://pics.10026.com/?src=/Anthem/Callback/CalendarFunctions.asmx/js"/> "text/xml-script">"http://schemas.microsoft.com/xml-script/2005"> <references> <add src="http://pics.10026.com/?src=/Anthem/Callback/CalendarFunctions.asmx/js"/>

<script type="text/xml-script"><page xmlns:script="http://schemas.microsoft.com/xml-script/2005"> <references> <add src="/Anthem/Callback/CalendarFunctions.asmx/js" /> </references> <components /></page></script>

And when I hit the URL above the javascript there looks correct:

Type.registerNamespace('WebServices.Callbacks'); WebServices.Callbacks.CalendarFunctions=new function() {this.path = "http://localhost:64408/Project/Callback/CalendarFunctions.asmx"; this.appPath = "http://localhost:64408/Anthem/"; var cm=Sys.Net.ServiceMethod.createProxyMethod; cm(this,"CheckDate","date"); }

So... here is the question: why is this undefined? I think this is a bug because when I debug the script the ".asmx/js" script is not loaded in the script explorer window like other referenced scripts. So, any work arounds? How else do I get this call to execute during the window.onload event?

Thanks in advance for the help.

The best thing to do I think is to install something like fiddler, and verify that the request going out is in the form you expect, and that you are indeed getting the javascript that you get when you use the script include. Hopefully you'll see something obvious...

Actually I think this might be a timing issue, you are probably calling your onLoad before atlas has a chance to load its scripts, so you can verify that is the case in fiddler. Anyways you probably want to register your getDataForTable on pageLoad or using atlas's ApplicationOnLoad.

Hope that helps,

You are right, I added the getDataForTable method after I posted this and it worked - it was just a timing issue. Thanks for the help though!

ATLAS UpdatePanel and parent/child windows

Hope someone can help me... I have a parent window that contains an UpdatePanel and from that parent window I open a child window or modal dialog window...

Is there a way when the child window closes to cause an UpdatePanel in the parent window to update/fire..?

Any help would be great..!

You can use JavaScript to submit the form containing the Update Panel, (for,submit()). You may also like to have a hidden input that indicates that the submission was done due to window closing. This will enable you to check for the hidden input on the server and call UpdatePanel.Update method on the server.

ATLAS replacing redered control ids incorrectly

I have multiple update panels on a page. When i fire a control event inside one of these panels, i get an alert window saying something like:

"An async postback was caused by a control within $ctl0$myPlaceholder$myUpdatePanel . . . but the update panel could not be found on the page."

when i view the source in my code, however, the actual id or name of the div that is the rendered updatepanel is "_ctl0_myPlaceholder_myUpdatePanel".

I am not sure why this is happening. has anyone seen this before? suggested fixes?

Hi,

you should view posts at:

http://gregdotnet.blogspot.com/ - about web.config element xhtmlconformance and
http://forums.asp.net/thread/1211330.aspx - about naming the controls

Basicly what you need to check is that if you have any dynamicly added controls assign them id's when they get added to the controls collection. This way the control id's at runtime don't get rendered with ctl04_ and such. Worked for me.
