Extenders not visible?

Hello. I'm new to the Microsoft developer environment...very new.

I installed Visual Web Developer 2008 as well as the AJAX Control Toolkit (3.5 with source). I installed the Toolkit and have all of the available mods in a separate tab. I added the script manager above the default form tag. If I drag and drop a standard button onto the platform I am not getting the arrow icon to view available extensions.

Is there something obvious I am missing?

Hi there,

The script manager should be placed just after the form tag, not above form tag. Please correct it.

It marks your thread as Resolved so we will all know you have been helped.

Moved the script manager below the form tag. Still no luck. Any other suggestions?

Hi, got the same issue. The Toolkit is installed but when I mark a button, I get no "Button task" where I can select Extenders. I run VS 2008 Prof.

Export to Microsoft Excel

Hello,
IE Functionality of Exporting tables to Microsoft Excel doesn't work properly when used with Asp.NET AJAX,

it always exports the first loaded data ignoring any updates done through AJAX Asynchronous post back

i.e. if a page is loaded with data X and then updated using AJAX update panel and
returned data Y then using Export to Microsoft Excel on this page will export
the first data X and not data Y

how can this be fixed?

Appreciate your help in advance.

maybe you can put some code here so that we can know what actually happen.

currently it work fine to me

Hello,

This is a sample of the code unfortunately i wanted to upload the solution but was not able to add files.

I have a master page, default.aspx and dataclass.cs

Appreciate your help in advance.

Evaluate a returned object from Client-side callback

Ok...I'm a n00b to the Microsoft was of doing AJAX - I've been using Prototype.

I ran the tutorial video for the client callback, and had that working correctly.

Unfortunately, my real-world scenario is returning an object which from what I've been reading is neatly serialized by the Microsoft AJAX stuff into a JSON string/object/"thing".

This is where my brain explodes.

I don't know how to get the information out of this ethereal "thing" that's being returned by my web service. I can see the "stuff" when I look at it with Tamper Data, but don't know how to get at it.

Here's my client-side call:

function GetLicenseeDetails()
{
var retVal = eval(GetLicenseeInfo.LicenseeInfo(document.getElementById('<%= ddlLicensees.ClientID %>').value, OnComplete, OnTimeout, OnError));
alert(retVal);
return(true);
}

The alert I've thrown in there just reports 'undefined'.

If anybody's got a good place they can point me to learn what I'm doing wrong, I'd appreciate it very much. I'm hoping it's something simple...

Thanks in advance,

Ric

Hi

The calls are asynchronous which means that the reqyurn value is not immediately available to you. You will get the return object only in the OnComplete method.

function OnComplete(retVal) {

alert(retVal);

}

Errors after Installing RC1 and the Dec CTP

Getting this one again: The type or namespace name 'UI' does not exist in the namespace 'Microsoft.Web' (are you missing an assembly reference?)

The following that I have checked:

1.) Made sure the System.Web.Extensions.dll was in the bin folder

2.) Copied and renamed the Web_CTP.config file to web.config and added it to my project

Anyone else hit this?

Make sure the dlls are in the GAC
Dropped them in the GAC, still no love.

Last step I know, check your web.confighttp://alpascual.com/blog/al/archive/2006/10/24/Manually-upgrading-from-Atlas-to-ASP.NET-2.0-Ajax.aspx

Little more information:

Created a new website for kicks on the same machine using the Ajax CTP Template. Works fine. Did a diff on the two web.config files and the only difference was:

<buildProviders>
<add extension="*.asbx" type="Microsoft.Web.Preview.Services.BridgeBuildProvider"/>
</buildProviders>

Took this out because it can only be placed in the top level of the site. Is there a problem with using this web.config file or adding AJAX specific settings in a folder below the root? I originally had all of this stuff in the top level web.config file, but was causing the problems described above so moved it ot the folder in which my ajax code was located.

It sounds like your referencing "Microsoft.Web" in your code somewhere (markup or code behind). The namespacing has all changed, so you'll need to modify all your existing references accordingly.
No references to that NS anywhere...

hello.

you're?talking?about?a?top?web.confg?file...are?you?saying?that?your?app?is?a?subdir?of?another?web?app??if?so,?then?you?should?make?sure?that?your?top?web?app?is?configured?to?use?asp.net?2.0?and?the?ajax?entries?should?be?put?in?that?top?condig?file.

another thing you should do: check for the scriptresourcehandler. make sure it's on your web?.config file. if this still doesn't solve your problem, use fiddler to see what you're getting from the server and then let us know.
MS changed the namespace in RC1 to System.Web.Extensions, this might be your problem. I had old statements in web.config from Beta 2 for Microsoft.Web.Extensions. I changed it to System and wham, it works. Give it a whirl.
