I'm using VS2008, and have installed Ajax controls. I can use UpdatePanel etc.. but on ther toolbar, there's no 'Calander' and other options. Also, I have no 'Extenders' anywhere in the toolbox.

AJAX Enabled Custom Control

ASP.NET AJAX Discussion and Suggestions — Sat, 04 Jul 2009 00:12:18 GMT

Hello, I'm trying to figure out what the best approach to a new project is. I'd like to write a custom control that, when I drop it on a page will (among other things) emit JavaScript code that will enable the control to make an AJAX call to one of it's own functions that retrieves data from the Cache object and updates a Label control with the data. I'm not sure what mechanism I should use to accomplish this, though. WCF and Web Services both require an external .asmx or .svc file and the manual registration of the service with the ScriptManager. I'd like to find a way to keep this completely encapsulated within the DLL so that I can use in it various projects. I can do this all without a custom control just fine by following...(read more)

AutocompleteExtender not displaying results on prod server

ASP.NET AJAX Networking and Web Services — Fri, 03 Jul 2009 15:15:59 GMT

I have an autocompleteExtender that I wrote on my dev server and wanted to promote it to my prod server but it won't display the results of my query. I am using framework 3.5 and vs2008 as my ide on both boxes. I can see in debug that the webservice retrieves the data, 100 zipcodes, from the sql2008 database. The webservice gets the results and places them in the arraylist to send back to the calling page but the results never appear. I simply copied the project library from one server to the other and then changed the database references. I am assuming that I have some version issue of os, ajaxcontroltoolkit, framework or something else. On my dev box this works fine. My autocompleteextender looks like this: <ajct:AutoCompleteExtender...(read more)

ScriptManager.RegisterPostBackControl problem

ASP.NET AJAX Discussion and Suggestions — Fri, 03 Jul 2009 11:21:44 GMT

Hi, I've created a web user control that have a FileUpload and a Button, and did put this control inside an UpdatePanel then register it like : ScriptManager.RegisterPostBackControl(Document1) and it worked OK. But the problem is that if I put another instance of my control and register them like: ScriptManager.RegisterPostBackControl(Document1) ScriptManager.RegisterPostBackControl(Document2) The second instance (Document2) works fine but Not the first one (Document1) and for that I'm assuming that only the second Document did get registered. So, how can register more then one control? Thanks Read More......(read more)

Background DB Checking? Eg Username Exists?

ASP.NET AJAX Discussion and Suggestions — Fri, 03 Jul 2009 05:18:50 GMT

Hi Guys, I have a user registration form, and would like to have a background Username checker.. That is, once the user exits the txtUsername TextBox, a background action happens, which checks if the Username already exists. I'm no Ajax or Asp.Net guru (yet), but could someone help me out with either ideas, or a link to where this might be explained? I think Ajax will do it for me, somehow, but not sure. The user should be able to carry on using the site while the check happens, so a postback (and subsiquent refresh of the screen) isn't really an option. Thanks. Read More......(read more)

Scriptmanagerproxy path to another server

ASP.NET AJAX Discussion and Suggestions — Fri, 03 Jul 2009 03:26:42 GMT

Does anyone know of a way to point the scriptmanagerproxy path to retrieve scriptresource.axd files or js from another server? For example: I want to use a content delivery network to serve the scriptresource.axd from in order for them to be loaded faster. If somehow the /scriptresource.axd can be modified to something like http://cdn.example.com/scriptresource.axd? that would be great Is it even possible? Any suggestions would be great... let me know if i'm going in the wrong direction or if there is another way. Also, there are something like 25 files, and three seperate scriptmanagerproxy's had to be created because it kept exceeding the 1024 limit. Read More......(read more)
