Updating an Application to the April CTP

Hello,

I am trying to update a web application to use the April CTP. I have refreshed the the Atlas .dll, but the application still seems to be referencing the March version. Any new application works fine when using from the Visual Studio Atlas Template based on the updates provided by the April CTP.

Is there a Manual way to make sure that I am using the newer version on an application that was started using the March version?Normally, you can't use March CTP and April CTP together. You have to uninstall the March CTP before installing the April CTP. From then, you applications written with the March CTP will now work with the April CTP.

Hope this helps
It's possible that your browser is caching the old Javascript includes I suppose - have you tried clearing your cache? Or setting debug=true?

Otherwise, if you've copied the microsoft.atlas dll into the bin directory of your app, I can't see what might be causing the problem.

Thanks,
Carlos

hello.

copying the new dll should solve the problem you're having. why do you say your app is using the march version?

Hi Luis,

It's not our app...it's the files that get installed. We are just now adding Atlas to our application. When the installer runs, it puts the zip files for the Atlas project into the Project Templates folder defined in VS 2005, and installs some stuff into C:\Program Files\<see previous post>. Those files, from what I can gather, is what is used for a new Atlas project.

When I create a new Atlas project after installing the April CTP, the Microsoft.Web.Atlas.dll has a file version of 2.0.50727.60309, dated 3/17/06, and the readme.txt that pops up has the same date in it. Unless I'm missing something, this is the March CTP.

All I'm doing is trying to install the April CTP and create a new app from it. I uninstalled the project templates from the location specified by the VS 2005 setting before running it, and it still put the March CTP files into that location. I'd suspect that it's providing a cached version of the project when it creates the new one, but even the files in Program Files are old.

Thanks,
John

Hey All -

It must have been some wierd caching either within our network or in the browser. I dusted off Mozilla to try downloading it; the first click downloaded the Mart CTP again. But downloading through the direct 'If your download doesn't start...' link got the correct one.

Very strange.

Thanks,
John

hello again.

well, yes, the files placed on the program files\microsoft asp.net\atlas are everything you need to deploy your app.

and yes, it looks like you have the wrong version. mine says:2.0.50727.60406

I guess I should have clarified... it seems to be using the "March CTP" based on the errors that still existed. After the removal of the March CTP and Installation of the April, all hot fixes work fine... except in an application that was created using the March CTP. That one does not want to update.

Thanks for you replies!

hello.

updating that app should be as easy as dropping the new dll on the bind folder. have you checked the version of the dll on the bin folder? according to your previous post, it seems like you're still using the olde version...

Updating and ASP Textbox from Server Side Script using AJAX Extensions

I've searched the web extensively and cannot find an answer to a question that I believe is simple.

I have an application running AJAX extensions so that scripts are run at server side. Everything works great. The problem I have is that based on selections in the script I need to base data to ASP.NET VB code behind to intergrate with an existing application.

Quite simply I want to update a hidden textbox then use that data to pass along to another asp page. I know how to pass the data once I get it to and ASP control. Just need to get it to the ASP side of the server.

Thanks in advance for any help.

Brian

I solved my problem.

Make sure there is an Name tag on the textbox that you will be using to pass info to code behind

This will accept a value and display it.

<inputtype="text"id="textbox1" value="JavaScript JumpStart"runat=server>

If you want to use the value in the code behind file this is what you need.

<inputtype="text"id="textbox1"name="textbox1"value="JavaScript JumpStart"runat=server>

Note the addition of the name tag.

Updating atlas and toolkit

If you already have atlas installed and created a new application via the atlas template in visual studio and are using the atlas "controls" how do you do upgrades when new releases of atlas or the controls come out? Will the new setup files update your system (templates,controls and apps) or is there something else that you will have to do?

You'll just need to copy over the Atlas assemblies in your \bin directory, and potentially update the Atlas settings in the web.config file.

Hope this helps,

Scott

updating only portion of a User control

Hi,

I Have an application Where I am dyanmically Loading User controls in a Main Page Content area(in an Update Panel)

And Each user control has its own update panel. for Example I have a List box and a text box and the Text box is in an update panel

And when the user select an item in the list box i need to update the text box upadate panel.

But the problem is since all these controls are in a user control and the user control loads in a place holder in an update panel in my main page.

To get the events of the user control child controls i need to load it again while asynchrounous post back

ie When user selects a menu item i am loading my user control into a place holder in an update panel in the main page.

and when the user clicks on the list box in my user control to get the selected index changed event i need to load the user control again

in my cs code. to the place holder . but i am only updating the text box in my user control. and so i placed that in an update panel.

but the problem is since my user control is inside an update panel in my main page the whole user control get refreshed.

I put the update mode of my main page update panel as conditional and when the user double clicks on the list box i load the user control in the palce holder so that i will get the events but i didn't update the main update panel. I did call only update for the update panel for the text box(which is in my user control)

but still my whole user controls get refeshed . Is there any solution for this

Thanks and regards

jereesh

Where the control that make posteback is located , is it inside your main update panel ?

if yes so you have to set "ChildrenAsTriggers" of your main update panel to false.

please let us know about your aspx code

HiI have a Main page where there is an update panel( where a place holder exists )which is made as conditionalAnd I have user controls(ascx) which are dynamically loaded into this update panel-into the place holder-(when user clicks on different menu items in main page. And inside each user Control there is an update panel where all child controls are placedand I may have update panels for individual controls in user controlfor example in one of my user control I have a list box and a text box and when i double click on the list box i need to change the text box value so i kept the text box inside an update Panel. but the problem is when i click on the list box in a user control if i need to get the event(selected indexchnaged) for that user control i need to load it again to the place holder in the cs file(Main.aspx.cs), ie if may user control name is search.ascxi am usong LoadControl method and adding it to the placeholder in my main page(this should happen each time when any postback occurs because of an event for a child control in the user control- then only i will get its events).I kept all update panel's update mode as conditional. and I will call only update for the update panelwhre my text box exists ( ie the update panel inside my user control). I only call Update for my main update panelonly when I need to load another user control ie when the user selects another menu item from the main page. mainupdatepanel -- Upadated only when new user control is to be loade usercontrolupdatepanel - Updated conditionally usercontrolchildcontrolUpdatepanel-- updates conditionallyThanks and Regards

Hi,

You have to set "ChildrenAsTriggers" of your main update panel to false.

Updating one updatepanle data from other updatepanel

I have a september ctp atlas dll. We have one updatepanel with timer which fires every 5 seconds & get application variable data from server.In second updatepanel we have a treeview which we want to update only if value in application variable changes.If we put timer in treeview updatepanel then treeview refreshes with images,nodes which we do not want.Can we add nodes in treeview from another updatepanel.Unfortunately, the treeview is not yet supported (as well as some other databound controls that use templates)...There are some hacks you can try in the meantime...for instance the gridview when template is not supposed to be supported but I have managed to get it to work by using a combinations of controls...another good post to read is this...

Uploading file in chunks using AJAX (or asynchronous call)

Hiya guys,

Just done some work with FileUpload in my AJAX-enabled web application, unfortunately using full-postback, so want to change it using AJAX.

Got some ideas, but not if that way will work, so need some bright ideas maybe from someone who already done something similar. Basically I want to achieve partial postback on uploading files in chunks, so not using the server's memory which can lead to server restart... Just saw some very interesting code snippets, but those were using ActiveXObject, which I would like to avoid.Is it possible to use a ScriptManager in some way to achieve similar results?
I guess it would be using XMLHTTP, as I already did some digging, but I mainly seen this using ActiveXObject.

Anyone with such an experience?

Thanks

Ben

hello.

old ajax code that needs to be ported to the asp.net ajax version, but it might still point you in the right direction:

An Ajax Alternative for FileUpload:

We've all embraced Ajax as a revolutionary technology, but many of us forget (or are not aware) of asynchronous posts in the times before XmlHttp requests. Our good old friend the IFrame used to be the preferred option for asynchronous http communications. Because an iframe is in essence it's own browser window, it can be used to fire off asynchronous requests (both POST and GET). However, even more important is an IFrame's ability to be a 'target' of a form POST. By adding an IFrame to the page and setting it as the target of the form post, you can in essence create an asynchronous file transfer.

Urgent - Trying to make Localization work (RC version)

I am going crazy with localization. It doesn't work :(

I have 2 projects: a web application (ajax enabled) and a class library with a server control.

I have this in my server control:

[assembly:

WebResource("SomeControl.myScript.js","text/javascript")]

[assembly:

ScriptResource("SomeControl.myScript.js","SomeControl.Res","SomeControl.Res")]

The myScript.js file is marked as embedded resource.

I have SomeControl.res and SomeControl.pt-BR.res resource files.

I have EnableScriptLocalization="true" in my ScriptManager.

I am registering myScript.js in the OnInit phase of the server control, like this:

// get script manager

ScriptManager scrMgr =ScriptManager.GetCurrent(this.Page);// register javascript fileScriptReference scriptRef =newScriptReference(

Page.ClientScript.GetWebResourceUrl(

this.GetType(),"SomeControl.myScript.js"));

scriptRef.NotifyScriptLoaded =

true;

scriptRef.ScriptMode =

ScriptMode.Auto;

scrMgr.Scripts.Add(scriptRef);

--

The problem is that the client side resource object is not being generated!!!

When I run the page and look with Fiddler, I have only the contents of myScript.js,but not the contents of the resources that I need.

I should have the contents of the resource files ready to be used client side.

I really need this feature and I am speding hours with this without success... I'd like to know if anyone here could make it work, and if possible, give me a help.

Thanks!

I found the problem :)

I must register myScript.js like this:

// get script manager

ScriptManager scrMgr =ScriptManager.GetCurrent(this.Page);// register javascript fileScriptReference scriptRef =newScriptReference("SomeControl.myScript.js","SomeControl");

scriptRef.ResourceUICultures =

newstring[] {"pt-BR" };

scriptRef.NotifyScriptLoaded =

true;

scriptRef.ScriptMode =

ScriptMode.Auto;

scrMgr.Scripts.Add(scriptRef);

Now it works...

Cheers!

Urgent Help Required

Hi All,

I am new to Atlas Technology. Just I started an application with Atlas but it is not working. I created web site using Asp.net Web site Template instead of using Atlas Web Site template. I refer Atlas dll in my application, then also it is not working, it shows an "Unknown Error" message. Can we use Atlas if the application opened in asp.net web site template. Or we must need to open it in Atlas web site template.

Can any one tell me what are all the requirements needed for Atlas based application, that is in Client and developing machine requirements. Whether we need JVM for running Atlas based application.

I just create a sample web application using Asp.net web site template. The page consist of two text box and two button. One button is "Add" and other button is "Back". If I press Add button it call server side btnadd_Click using Atlas. But it is not working. I am pasting my code here please tell me solution for this.

<atlas:ScriptManager id="scptMgr" runat="server" EnablePartialRendering="true" />

<asp:TextBox ID="txtAstClassName" runat="server"></asp:TextBox>
<asp:TextBox ID="txtAstClassPrefix" runat="server"></asp:TextBox>

<atlas:UpdatePanel Mode="Conditional" ID="atlasUpdate" runat="server">

<Triggers>
<atlas:ControlEventTrigger ControlID="btnAdd" EventName="Click" />
</Triggers>
</atlas:UpdatePanel>
<asp:Button ID="btnAdd" runat="server" Text="Add"

OnClientClick="AddUpdateAssetClass()" OnClick="btnAdd_Click" />
<asp:Button ID="btnBack" runat="server" Text="Back" />

I set web config like this

<

<

add namespace="Microsoft.Web.UI" assembly="Microsoft.Web.Atlas" tagPrefix="atlas" />
<

add namespace="Microsoft.Web.UI.Controls" assembly="Microsoft.Web.Atlas" tagPrefix="atlas" />
</

controls>

In this I call server side Add Click event in Atlas Trigger. But It shows error.

It is very urgent Please help me, Any sample program which is created using Asp.Net web template and Atlas pls send to me.

Hi,

if you are working with the ASP.NET WebSite template, be sure to reference the Atlas dll but also to update the web.config (the changes you made to your web.config are not enough).

The easiest way to update the web.config is copying it (or the relevant sections) from the Atlas WebSite template.

Hi

I refer dll in my application and I get this config information from other project which is created in Atlas Web Site template.

I just include add button event in atlas trigger, that shows error.

Use Asp.net ajax with running the installation program.

Can asp.net ajax be deployed to a production server via a xcopy operation (as part of the application)? Is it possible to deploy without having to have the server admins run the ajax installation program on the production server?

Thanks

Copy the System.Web.Extensions and System.Web.Extensions.Design from the GAC of your local pc into the bin directory of you production server. Ensure that your web.config has the required setting for Ajax Framework.

How to copy System.Web.Extensions and System.Web.Extensions.Design from GAC? Can I copy this assemblies from C:\Program Files\Microsoft ASP.NET\ASP.NET 2.0 AJAX Extensions\v1.0.61025?

Whats the "required settings"?

Is that enough:

use httpHandler of AJAX in web application

Hey all,

I want to implement AJAX in my current running web application.

I am going to use .

<httpHandlers>
<remove verb="*" path="*.asmx"/>
<add verb="*" path="*.asmx" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
<add verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" validate="false"/>
</httpHandlers>

in my web application.

I want to know ...

(1). will there be any side effect of the above code,

(2) will my current functionality got affected.

(3)what this code is all about and what it does.

1. No your should not see any side effects

2. The functionality should remain intact.

3. All this does is tell the webserver that when it gets a request for an .asmx page, to use the System.Web.Script.Services.ScriptHandlerFactory, and System.Web.Extensions classes to handle the request. for all verbs. So you .aspx, .ascx, etc will go unchanged and will continue to use the default HttpHandler. It then tells the web server to that when you recieve a GET or HEAD request for the ScriptResource.axd to use the System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions classes to handle te request. But since these classes extend the default classes that would normally handle the .asmx requests, then all your existing .asmx requests will work as originally intended. The above classes add the ability to JSON serialize requests for use with AJAX webservice calls.

Hope this helped clear things up.

thnx aquillin.

When I was not using the above code , I was getting error like "sys is undefined".
Yesterday I was reading an article and it said that the code generates the required javascript as AJAX uses it.

you said "All this does is tell the webserver that when it gets a request for an.asmx page, to use the System.Web.Script.Services.ScriptHandlerFactory...........,"

I have one dought that what is the link of .asmx (asp.net web services here). I am not using any web service .

Am i using them as hidden ?

The code actually doestwo things. One is the handling of .asmx web services. The other is handling of calls to ScriptResource.axd. That's required to deliver the Microsoft AJAX Library to the client.

It shouldn't affect your application unless for some reason you were already using something called ScriptResource.axd (extremely unlikely, but just being complete).
