Accessing control extender behaviors in javascript

Hi there,

I'm using the AJAX 1.0 Beta 2 extensions and the AjaxControlToolkit. I'm finding it extremely hard to access the behaviors associated with a given control. (I'd like to hook into the expandComplete event of an CollapsiblePanel).

I've tried using the following:

var cp = $get('IdOfMyCollapsiblePanel');
cp.get_behaviors()[0].add_expandComplete(MyHandlerFunction);

This results in an error with the get_behaviors() call.

Can anyone post an example of how to hook up a javascript method to an extenders event? (client-side)

I'd really appreciate it!

Jeremy

And here I go replying to myself...

I found the source of my problem. I was trying to set up the event handling in the pageLoaded event that is raised by the PageRequestManager, but the behaviors are not yet loaded at this time. Instead I hooked the Sys.Application.load event and everything works!

Accessing a WebService-Method

Hello, i was migrating from Atlas July-CTP to Beta 2.

Now get an error when i call my webservice from javascript and the message is talking about System.InvalidOepration and authentication failed,

but only when I mark the corresponding method with EnableSession= true. In Atals JulyCTP the same call worked fine. Is there maybe a change in security-model?

Did I forget something or a declarartion is not set right?

Can anybody explain?

Hallo Michael,

can you show us the code of youre WebService definition?

Check to see if your Web service definition has the ScriptService attribute (http://ajax.asp.net/docs/mref/8bb8cdde-6050-e492-e72a-eed2242c213c.aspx).
I believe the CTP version didn't have this attribute.

This method is'nt accessible, it's called from pure javascript in a javascript-source file.

Hello Michael,

maybe i'm wrong, but for me is VOID in a webservice a "not so god idee". You get absolut no response from this methode. It's not better to create an object with a returnvalue and react to the returnvalue?

It's only a idee.

The web service code seems OK. I don't know exactly how you're invoking the web service.
As you described, probably you don't have an aspx page with service reference configured using this web service. Adding a service reference to your page, makes AJAX download or include in the web page the proxy code (depending on the parameters you provide).
Check the proxy code that your service generates and see if it helps you (you can check that looking athttp://yourserverver/yourService.asmx/js - you just include /js after your web service address).

HTH,

Access a server-side control from JavaScript in beta 2

Sorry if this has been asked already, I tried search but no luck.

Okay, I have a server-side control defined as

<asp:Textbox id="textboxonserver" runat="server" />

What I want to achieve is to set the value of this control from client side javascript. document.getElementById("textboxonserver") won't work since the real id on page is something like ctrl$palceholder$textboxonserver. Tried $find, still nothing.

I know I can get the value by doing something like

My.prototype = {

_textboxid: null

...

Then set the textboxid = this.textboxonserver.ClientID inside the pageload() loop. But isn't this a bit overkill just for that purpose.

Thanks

nvm...i found the answer myself:

inside my javascript I can actually do this:

var txtboxid = "<%= textboxonserver.ClientID %>";

then use document.getElementById(txtboxid) to get the object in DOM tree. Just not sure if this is the elegant way to do this although it works..

ugh...sorry problem still stands..

A simple question: Do webservices work with the beta?

I can't seem to get of my webservice to work. All I get is object undefined. I have javascript that gets triggered on an onblur() event which calls a webservice where the code is in another file. Nothing I do will get it to work. I've tried all the solutions I've found and still errors.

Same goes for cascadingdropdowns. It's like my webservice is invisible. I read the sticky about putting the webservice call in the aspx file and I did that but it still can't be found.

I find that the documentation is limited and what I do find, it seems to be written for experts. So, I guess for now, I have no option but to dump the path I'm on since it appears to me the code isn't ready for beta. Too many issues. Not enough documentation and examples.

Very frustrated!

Hi jax67, can we see the webservice class and the javascript function that calls it? Also the error message that you are getting. Maybe I can help. I used cascadingdropdowns a lot too, it was very frustated at first, but then I figured it out. So, everything is all good now.

Thanks AW - I am so frustrated :( The first file is in a folder called Maint (off of the root) and the webservice asmx file is in the root. The code for the webservice is in app_code.

Here is the code that has the javascript call. The onblur is what calls the javascript and that part works. It's the actual call to the service that fails. I put an alert before the call and the alert is displayed. A javascript error occurs after I dismiss the alert. I do not have the alert code in the following code files.

Thank you for any help you can provide. I really do appreciate it...

Dave

I seem to have it working. I created a new website (using the CTP version) and then used the web.config from that project. I migrated my appsettings and an Oracle assembly and then moved my webservice in the folder where the files calling it resides. For now, I'm going to leave it as it is.

Thanks AW for your assistance!

A question about Beta 1 and Beta2

I have downloaded the beta1 from the ajax.asp.net,and it includes 3 dll files:AJAXExtensionsToolbox.dll,Microsoft.Web.Extensions.Design.dll,Microsoft.Web.Extensions.dll

when the ajax 2 was published, I download it and refresh the beta 1 use it.

it run all ok in my computer.

I copy the source file to another computer,and set up ajax beta 2 at that computer.

it run ok, too,but when I choose the designer,the ajax controls were all error.

Don't do that, make sure you uninstall beta1 from you developer computer and then install beta 2, even coping the file does not work as the installer adds the files into the GAC

oh,sorry,I describe it not clearly.

I don't use copy.

I unnitall the beta 1 and set up the beta 2 .

what should I do?

thank u for your reply.

What exactly do you mean by what do you now?

Are you experiencing errors with the previous Ajax App? Recompile and programming should come as normal.. we are a little confused by the what to do now...

If you are missing the Intelissense, some have reported that changing the web.config entries to reference something like ajax instead of asp.. provides it... Others working with MasterPages find as long as the master page is open in the designer it works.. see my blog entry ontech-review.org for web.config entries and other install tips...

Check you web config to make sure all is resgistered for the Beta 2 :

http://alpascual.com/blog/al/archive/2006/10/24/Manually-upgrading-from-Atlas-to-ASP.NET-2.0-Ajax.aspx

OK.

the ajax beta 1:I downloat and install it.the default file include files:AJAXExtensionsToolbox.dll,Microsoft.Web.Extensions.Design.dll,Microsoft.Web.Extensions.dll

and the ajax beta 2: in another computer( it have never installed the beta 1,it is pure).I install the beta 2 directly.

but the default file noly inluce Microsoft.Web.Extensions.dll.the vs.net toolbox have no ajax control.

I add ajax control into toolbox.and add it to a website.

the website run ok.but the control response error in the design view.

I have modified the pre from asp to ajax.

thank you for your reply.

albertpascual,thank you for your reply.but the link I can't open.
What error do you get opening the link?
