.NET 3.5 and VS SP beta1 goodies
Mon, May 12 2008 20:58
You can get them from here (VS) and here (.NET). I'm reading what's new on Brad Abrams post and I'm really digging the new features:) For instance, having the format option working with JS code is simply cool! Another cool thing: the ScriptManager is able to combine scripts so there's really no need for using the ToolkitScriptManager for that... Read More...

The dataItems dictionary
Mon, Mar 24 2008 20:50
Today I noticed that there are still many guys that don't know about the dataItems property which is exposed by the Sys.WebForms.PageRequestManager. So, I decided to write a small sample that will show you how to use it when you're using partial updates and need to send some info back to the client during a partial postback. So, here's a really simple... Read More...

ASP.NET AJAX: generating the proxy's JS code on the fly
Mon, Jan 7 2008 23:45
Before talking about the ProxyGenerator class, I'll have to add one more observations on the previous posts on the new role service: for the code I've shown to work you do need to have an authenticated user. The easiest way to see the previous code working is just to create a new login page which uses the FormsAuthentication class to authenticate the... Read More...

ASP.NET AJAX: the new role service
Sat, Jan 5 2008 23:54
The latest version of the ASP.NET AJAX framework added a new client service which will let you get info about the roles of the current user: I'm talking about the Sys.Services._RoleService. The class exposes two important methods which you might end up using if you need to get info about the roles of the current user: get_roles: returns an array with the... Read More...

Changes on the authentication service
Sun, Nov 25 2007 22:59
Now that the 3.5 version of the platform is out, it's time to start digging in with Reflector. Since I was experimenting with the authentication service to try to answer a question that was posted on the forums, I couldn't stop noticing that on ASP.NET 3.5 the AuthenticationService is now... a WCF service. Besides that, there are also some other cool... Read More...

Stop the nonsense: don't put the System.Web.Extensions.dll inside your bin folder
Thu, Nov 22 2007 22:07
First, if you've already installed the last version of the framework, you can relax since it will automatically put the ASP.NET AJAX assembly on the GAC. Ok, if you're still using ASP.NET 2.0, then keep reading. As we all know, ASP.NET AJAX was introduced as an add-in to the ASP.NET 2.0 platform. During the early CTPs, you used to put the dll inside the... Read More...

ASP.NET AJAX:Registering your script during a partial postback call
Thu, Nov 15 2007 10:53
By now, everyone knows that you should use the RegisterXXX methods of the ScriptManager class to insert a script block during a partial postback (that is, when you're using ASP.NET AJAX and UpdatePanels). Even though this is "common knowledge", what most don't know is that using one of those methods and associating a script block with a page... Read More...

Changing the contents of the UpdateProgress control
Mon, Nov 12 2007 23:15
Today I've answered a question on the ASP.NET AJAX forums that asked something like this: how do I get a reference to the controls defined inside an UpdatePanel or UpdateProgress controls? The first part is easy: just use the ID of the control. The second is not as easy as it might seem at first. The problem is associated with the way the control isntantiates... Read More...

Deployment problems with ASP.NET AJAX applications
Fri, Oct 26 2007 14:55

Generally, the error that has been reported is: Could not load file or assembly 'System.Web.Extensions, Version=3.5.0.0... One of the suggestions that I have seen is to add a redirect on...

ASP.NET AJAX: some ideas on how to export the contents of a GridView to an excel file without a full postback
Wed, Oct 17 2007 23:08
In the last few days I've returned to the ASP.NET AJAX forums. One of the most requested features I've seen is generating "excel responses" (do you think i should copyright the term? :) ) from data presented on a gridview. There's already a known strategy for doing this kind of stuff from a traditional ASP.NET page: we start by clearing... Read More...

No, you cannot call Server.Transfer on an ASP.NET AJAX enabled page
Wed, Oct 10 2007 20:24
Even though ASP.NET AJAX has been here for some time, this question still pops up on the forums. So I thought I should put a post here and redirect future questions on the subject to it. Well, to be precise, what you cannot do is call Server.Transfer (or other transfer method - btw, if you're using IIS 7, there is a new TransferRequest method that might interest... Read More...

While I was hanging around the AJAX forums, I found this interesting thread . The problem was a stack overflow, but the interesting thing was what was causing that error in the first place. here's the scenario: a top page has a method that receives an object. It also has an iframe which loads another page. Both pages load the same custom js file that defines... Read More...
