AJAX Beta 2 and Toolkit 61102 released but missing CalendarExtender, TabPanel and TabConta

Any idea if these are likely to be put back in as I finally got them working?

Calendar and Tabs currently only exist in the Development branch as they are not yet stable for release. I believe that the beta2 changes in the Release branch will be merged back into the Development branch soon.

I have 55 pages using Tabs now and about 40 other pages that need the fixes in the Beta2 release.

This now makes it difficult to decide whether to temporarily code out all the Tab panels somehow and replace them with something else or wait until Tabs are back in the Toolkit.

Any idea when the Tabs will be back in? Guess?

Help...please...

I'm looking at migrating Tabs right now, but keep in mind tabs is currently still in development and is not fully stable enough for the release branch. Its implementation may still change slightly before it hits the release.
Thanks. Much appreciated.

AJAX Beta - Undo the changes

It was going so well. Everything worked great, now I have to rewrite my app. Whoever had the idea to require extenders to be in the same panel is fired. This is killing me.

An extender can't be in a different UpdatePanel than the control it extends.

Description:An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details:System.InvalidOperationException: An extender can't be in a different UpdatePanel than the control it extends.

hello.

well, that's just to guarantee that you don't get orphaned extenders...

Ajax based custom control with web service

I want to create a simple reusable search pane control.

The idea is to have a textbox and a button. When you press the button you trigger an AJAX call to the server with the textbox value as parameter. The AJAX call then bridge the request to a web service that perform the database search an return a dataset. The dataset is then binded to a repeater in a updatepanel to display result. I've been using a WCF service for the web service.

This work fine if I host the textbox, the button and the result detail ascx file in a ASP.NET Ajax Enabled WebSite.

I try to move this part to a user web control, including the ascx files in resources. I hit the following problem: When I include the control (compiled assembly) in a ASP.Net Ajax Enabled Web site, the control display correctly but the AJAX call fail.

I think that the ScriptManagerProxy setting the AJAX service in my user control fails to find the path of the asmx ServerScript definition within the assembly.

Do you have any idea to make this work smoothly, ideally with only the assembly included in the website project?

Thanks in advance for your help

Web user control is not only an assembly, which should include .ascx file and.ascx.cs or.ascx.vb file.There is only one asp:ScriptManager in a Ajax web form. I once tested a Ajax enabled web user control and placed it in a common web form.I found it worked fine. Can you post some codes here? We are going to test it.

AJAX Baby Steps - removing an item

i am working on my first little ajax project.

Basically i have no idea how to start. I created a AJAX enabled website and i have a simple page on there that basically has a list of items taken from a Class thats stored in the session.

So I have

1 Gridview that bases its DataSource to a Dataset i create from a object (just a class that contains an array list)

2. I have methods in place to loop through the array list, create a datatable and bind it to the gridview

3. I have a method that also removes a selected item from a dataset and refreshes the gridview its a "remove" button.

I would like to have AJAX handle the removal of items (for now, eventually i want the whole thing ajax enabled) but just to start i want to just activate my Remove method from ajax.

But i dont know where to go from here.

So what do i have to do to call my method via AJAX ?

Any advice or help appreciated!

thanks

mcm

well i seem to have figured it out although i dont know what i did or how it works!

I added the ScriptManager tag to the page.

I added an UpdatePanel surrounding my Gridview,

and now my REMOVE buttons work without postbacks!

Holy Momma! How did it do it?!? I thought i'd have to be writing javascript and hooking into new events , etc.

is it REALLY all this easy?

mcm

Yep, it can really be that easy. caveat, though; the UpdatePanels can get pretty heavy in terms of resource requirements if you use them extensively, and there are also issues with certain combinations of controls (witness the volume on the forum of "Update panel and my..." posts. For simple things like you're describing, they work very well, though.

great! So now that i have seen how easy it "can be". I do have a couple more questions.

I created a sample AJAX enabled site to test this bin and it works GREAT im so impressed with myself.

But how complicated is it going to be to make this a component. My idea for the site is to use Master Pages (another first for me)

and down the left side this "component" will sit. I still dont know wether to make it a component or just a content page.

There will be a repeater or a formView on the right with products to add to the bin. I want those to be ajax enabled too. Is it hard to make different elements in different content pages "speak" to each other? Really all im doing (as stated in the first post) is adding items to a Collection stored in a Session Variable (using a facade pattern with a SessionManager class)

Also. I am using the new Web Application templates to build my stuff (from ScottGu's blogs) Can i switch this AJAX enabled site to be a WEb Application and keep the functionality?

thanks,

mcm
