very weird problem

I have installed lastest ajax and also toolkit too. I created master page and default aspx page, then I put my scriptmanager inside the master page and update panel inside the default page, I didn't choose ajax enable website because I have a hard time to place my existing web.config files, assemblies, connection strings to right place of the enable ajax's web.config file. Maybe I should though, with this error.

I get errors sometimes with all the controls in update panel, is not recognized my html tag, even though my controls are declared, it says it is not, But it builds application suscessfully. I made sure I put this

<%@dotnet.itags.org.RegisterAssembly="System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"Namespace="System.Web.UI"TagPrefix="asp" %>

to my page and also in web.config file under config section also assemblies too. Thing is I think every time I backup my website to my documents, for some reason a while later this happens. I even reset my iis to clear my temp folder of asp.net too. Still. Why this is happening ?

You'll also need an reference to the following assemblies:

- AjaxToolKit.dll
- System.Web.Extensions.dll

You can do this using right click on your project, "Add Reference" and point to this DLL's

On bin folder, I have got these ar, cs, de, es, fr,he,hi,it,ja,ko,nl,pt, ru,tr-TR,zh-CHS, zh_CHT all
thas AjaxControlToolkit.resources.dll in it.
Then AJaxCotrolKit.dll under neat AjaxControlKit.dll.refresh and AjaxControlKit.pdb

Microsoft.Web.UI.WebControls.dll with Microsoft.Web.UI.WebControls.dll.refresh

I have these dll on my bin now, and still problem

I had these dll on program file but not pointing to my project. I am right clicking my project and add references, choosing these dll and adding but it is not showing under my bin folder for some reason, can someone tell me steps to how to add these dlls to my projects.

Is anybody didn't have this problem? I go crazy here with this..

this was nothing to do with ajax, it was copy paste problem..

Very weird error. Ajax controls call default.aspx

I have a few pages in my site... and for some reason, if there's any ajax controls on the page, it calls default.aspx and runs the code every time any aspx page with an ajax control exists on it. Problem is, default.aspx resets my session variables.

Why does Ajax call the default.aspx page code? It only runs the CS file... it doesn't actually show the default.aspx page.

I doubt it calls it. Do you have a component in your site somewhere that's got a url of "/" attached to it somewhere, and that's invoking the default page?

it only seemed to only happen when I have Certain Ajax controls on the page. Note, it only does it with Internet Explorer 6 and 7. Firefox seems to be fine.

For example, I have a collapsible PAnel in each row of a Gridview. That is in an UpdatePanel. When the Gridview is populated (and I have a breakpoint on the default.aspx.cs file), it goes through that code. Well, I set my session variables on that page, so in essence it resets them.

It seems like it does this AFTER the page is loaded, because the labels that show content based on those session variables aren't updated until I go to a new page.

It only does this when I have a collapsible panel in IE. The panel is set to collapsed.

Actually, it appears that AJAX is clearing the Session Variables. I don't know where it's doing this, though.

ViewState and Atlas

Hi

I encountered a problem involving viewstate and PageMethods (web methods in an aspx page).

I was submitting some control values, only one control on the page is designed as a <asp:listbox />, the rest of the controls are generic HTML. While Atlas.js constructed the proxy to the PageMethod and the arguments (Web.Net.PageMethodRequest) the Atlas.js javascript does some sort of check on the page controls, in which viewstate is a hidden input, adding it to a dictionary (refer line 3495 in Atlas.js)

Some sort of exception is generated but no information is available to determine the source. The code behind to the PageMethod didn't get hit in debug mode and it wasn't until I inspected the request/response in Fiddler that I came across a message indicating a corrupted viewstate.

After disabling viewstate on the <asp:listbox> the request got through to my [WebMethod] in the code-behind.

There is a problem with PageMethods and viewstate, or have I missed something.

Craig

An update for those who might be encountering the same problem with altas (Jan-06 CTP) and ViewState.

As mentioned in my previous post, in the file Atlas.js on line 3495, a procedure adds to the variable bodyDictionary all 'submittable' HTML element e.g <input /> this includes <input type="hidden" /> which means that<inputid="__VIEWSTATE" /> is added to the bodyDictionary variable.

Next in the procedure, is a call Web.Net.WebRequest.createQueryString(bodyDictionary, ...);

This is where IMHO the viewstate corruption is occuring between the client service calls to the server. In my case, I make a call to a [WebMethod] which is contained in an aspx page. So my client function is something like this:

functionfoo() {
PageMethod.GetFoo('hello');
}

My aspx.cs [WebMethod] is like the following:

[WebMethod]
public string GetFoo(string text) {
return text+=" get foo";
}

My page wrapes a user control in an<atlas:UpdatePanel>the user control contains an<asp:Repeater>control.

Has anyone experienced this, or am I the lucky one? To avoid the error 500, I removed the check for HTML elements with a type of hidden. But I'm not sure if this is a good thing...

Craig

PS: I can post the stack trace for those who might be interested.

Further, using PageMethod seems to faciliate the viewstate corruption. for kicks I moved the [WebMethod] from the aspx page into an ASMX file, reversed my Atlas.js script hack and the viewstate problem has gone. I hope the PageManager is a little more robust in the rtm.

Hi,

I'm not able to reproduce the behavior that you described. Could you post the stack trace and also the relevant page code?

<unsd:ExchangeRateControlid="exchangeRateControl"runat="server"/>
</ContentTemplate>
<Triggers>
<atlas:ControlEventTriggerControlID="buttonSave"EventName="Click"/>
</Triggers>
</atlas:UpdatePanel>

The ExchangeRate control is populated in the Page_Load event of the aspx Page by passing an array to a property accessor in the control, the array provides is the data source to a repeater. The ItemTemplate in the repeater contains a link to invoke the GetExchangeRate javascript in the page (above).

Hope this helps.

I don't know if its the same issue or not, but viewstate corruption is rampant in the QuickStart tutorials... There were several times where I ran 3 or 4 different "run this" tutorials in a row only to have the viewstate corruption error message appear on me. Sometimes it was fixed with a refresh of the page, sometimes it never went away.
hi Guys...
even i got the same problem when i put my [webmethod] in code behind.i tried removing type=hidden from atlas.js line 3495 and it is working.please let me know for the solution as we just can not remove any thing from coreatlas files even though doing the same results in expected output.

thanks
Jaideep

I tried a few things, but was not able to repro. Could you give this a try with the March CTP to see if it still happens?

thanks,
David

I have a similar problem with teh session state.

I have narrowed it down to a web user control that raises an event.

The code behind that implements the event sets the session var and then does a redirects.

on the redirect page the session state is blown away. cant figure out why

steps to reproduce

- create a web user control (define an event and raise it)

- create a page and place the wuc on it (trap for the wuc event and set a session var and do a redirect to 2nd page

- in 2nd page Page_load check the session state

Visual Studio not giving me Atlas option

Hello all, I have installed all of the Ajax stuff (located here:http://ajax.asp.net/Default.aspx) but when I open up Visual Studio and go to New Website I do not see option for Atlas. Anyone know why this does not show up? Thanks, Victor Gaudioso

Hi,

Support for AJAX (the new name for ASP.Net ATLAS), is included in SP1(came out last month), for VS 2005 (and I believe the Express edition too). If you have an older version of VS, I'm not sure what you'll need to do. Good luck. BRN..

want to pass datatable (.net) to javascript function

hello,

i have a datatable stored at page level (in aspx). i am binding this datatable to gridview object which has a checkbox column for row selection.this table may contain about 500 to 1000 records. when ever i check/uncheck this checkbox, i want to update this bound datatable without posting back to server.is it possible through ajax/javascript ?

pl. provide solution for this asap...

Jayesh Shah

You will have to post back to the server if you want to update the DataTable as that is a server side object. However, you could use a UpdatePanel around the GridView to hide the fact that a full postback is occurring.

Watermark and Popup Calendar issue

David, I download the lastest toolkit, and try the following code in aspx page. It is OK. But when I put it into a user control. It won't work!

The error is caused by code when clicked on popup calender:
var mydate = $("TextBox1").mydate;
The error message is Object is required

Web page and User control

Good morning ladies and gents. I need a help with the following scenario:
I have a web page and two user controls.
a web page(ASPX) namedWebPage.aspx
a user control(ASCX) namedUserControl1.ascx
a user control(ASCX) namedUserControl2.ascx

TheWebPage.aspx has a user controlUserControl1.ascx bind to it and then user UserControl1.ascx hasUserControl2.ascx in it.(See below)
InsideUserControl2.ascx page a have a TabContainer control namedTabs. It has a methodOnClientActiveTabChanged="ActiveTabChanged".
ActiveTabChangedis JavaScript function (see below) inside aUserControl2.ascx

function ActiveTabChanged (sender, e)
{
__doPostBack('<%= Tabs.ClientID %>',sender.get_activeTab().get_headerText());
}
So basically when you switch from one TabPanel to another it should do a post back.
My problem is that Java Script function not getting triggered; it is only fires when I put it intoUserControl1.aspx but now facing a problem like "Tabs"control not exist onUserControl1.aspx .

My question is: How can I executeActiveTabChanged function to get a post back?

Thank you for your help.

Are you sure the real Tab.ClientId is written into the client code. You might want to compare what it is actually writting (you can do this with the source view on IE).

Yes, i did compare what's in the view source and it looks fine to me.

Thanks for reply
