Is this still available? I am unable to find it when I try to add it to my Toolbox.
It is not a default asp.net Control as far as I know, maybe the control you're looking for is a third party control?
The Asp.net Ajax Control Toolkit has Tabs, that might do what you want.

Where can I find a MessageBox Control for my ASP.net web application? It has to be free and simple.
If you use the ASP.NET AJAX Control Toolkit, you can use its ModalPopup extender. Alternatively, jQuery has a plugin you could use.
How's this for a poor man's solution? :)

You could use the jQueryUI Message Box.
Does anyone have, or could point me to, an example of using jQuery to page through an ASP.NET datagrid control?
I would like to page through a large set of data displayed by an ASP.NET DataGrid control however I would like to avoid a page refresh and hence want to use AJAX to get the new sets of data. I would also like to avoid the ASP.NET AJAX toolkit and would like to do it all using jQuery-AJAX. Thank you.
The DataGrid is a server side control that relies on postbacks. jQuery and AJAX are client side technologies. Write a AMSX or WCF service to serve up your data and consume it with jQuery. You can use jQuery templates to make things easier. Or wrap the DataGrid in an UpdatePanel and you will have the poor man's AJAX(sometimes called AJAH).
There may be a jQuery plugin to help with this.
Here's a nice article to get you started:
Easily build powerful client-side AJAX paging, using jQuery
Try using jGrid, it´s free, but there are commercial dotnet implementations available.
It´s quite powerfull,you can do almost everything with it. And loading your data is easy to. But, you have to forget the Idea of aspnet datagrid, unless you will use updatepanel(which is very stable and usefull and has nothing to do wiht asp net ajax toolkit)
I am currently working with ASP.NET and the person who designed the form has used all Server Controls for things like TextBoxes and Dropdowns etc when really they are not providing postbacks.. Some of the dropdowns and textboxes are values that I need only in jQuery so as far as I can see there are no drawbacks to coverting these controls to standard html controls rather than ASP.NET server controls?
I suppose I will need to continue to have my GetDataGrid button as a server control because I will need it to postback (and receive PageLoad events etc - all asp.net events) to update the GridView? Or would it be possible to use the GridView (ASP.NET server control) from a Webmethod and call it via Jquery?
Of course in my webmethod I would need to the instance of the gridview to add the datasource - but I don't see how this would be possible without being in the ASP.NET events - or maybe I wrong?
The other thing I thought of was changing the GetGridView button to a standard HTML and calling the javascript postback from the client click event?? This way it would do a real postback and I would end up in Page_load.
Taking everything into effect i don't want to the change the GridView asp.net control as it funcions well as an asp.net server control but i am unsure how i would do this.
I remember a document being available that said "how to use asp.net webforms without server controls" but i can't seem to find it. I suppose using webforms like asp.net MVC - but i can't change the project to MVC - its out of my control.
I would love to hear some feedback with regards to how to do this or comments etc.
I find ASP.NET webforms to inject a lot of code smell into pages - I am using .NET 3.5 so a lot of the output is with tables etc...
If you use Request.Form["..."] then you can get the information which was filled in in standard html input fields.
Instead of keep on using the GridView control I suggest you take a look at either jqGrid or the new templating system that Microsoft put into place for jQuery (currently a plugin but expected to be part of core jQuery from version 1.5 on). These can bound to json which can be retrieved from a webmethod or pagemethod call to fill up the template with data.
Also i don't think its possible from asp.net (code behind) to receive values of an html >control without it having runat=server.
Use webmethods.
Set a client event (like 'onchange') on the html control and then in javascript function called when the event is fired you can use PageMethods to send your data to the code behind.
Some thoughts...
The GridView can't be created in a WebMethod and even if there was a way to get that to work, you'd be better off going with a genuine client side grid. As that's not an option, I don't think there is too much point in trying to make any major changes to your existing pages.
ViewState
Changing the textboxes, buttons etc to HTML versions, would gain you a little bit in reduced Viewstate size but add a bit of complexity in how you handle interactions with the page. You can add runat="server" to HTML controls which will give you control over what is rendered and still have access to the control on the server side.
.Net 4 gives you far more control over viewstate but unfortunately in 3.5 its not as easy.
The GridViews
You could wrap the GridViews in UpdatePanels. That's a 'cheap' way to add some interactivity to your pages although you won't be gaining anything in terms of performance.
It's also still possible to manipulate the Gridview using jQuery on the client-side. There a lots of tutorials, blog posts etc explaining how to do this on the Internet.
MVC with Webforms
Its also possible to mix ASP.Net MVC with Webforms in the same website. As it sounds like you are familiar weith MVC, you might want to consider this approach for any new pages. Here's a blog post explaining how to do this.
Update:
Here's a more recent article by Scott Hanselman on how to use MVC with an existing Webforms application.
I am working on a page that primarily uses Telerik RadControls, and thus uses the RadScriptManager control. However, I need to add some controls that use AjaxControlToolkit to the page, but since I cannot have two ScriptManagers on one page, so how would I do this?
You are correct in that you cannot have two script managers on the same page.
However Telerik can use the standard Microsoft ScriptManager, and your Microsoft controls can also use the Telerik ScriptManager. You just have to choose which one you prefer. (I suspect you should try Telerik to start with)
How can we refresh a web user control automatically without a page postback in asp.net 2.0? i have tried meta tags in controls head tag but it also refreshes the whole page.
You could try implementing a little bit of the ASP.NET AJAX Framework into your app and wrapping that control in an UpdatePanel. It will work with .NET 2.0
Edit: Here is a quick link to a tutorial on using the ASP.NET AJAX UpdatePanel: http://ajax.net-tutorials.com/controls/updatepanel-control/
And here is the official introduction page from the ASP.NET website: http://www.asp.net/Ajax/Documentation/Live/tutorials/IntroductionUpdatePanel.aspx
User Controls are server based controls. Your only option might be some type of javascript but depending on what you are try to accomplish, unlikely.
There are several ways to do it and it depends on what your control is made of.
One of the easiest ways to do it is to wrap the control in an UpdatePanel and then use a Timer control to just update that UpdatePanel. But that might be expensive in terms of viewstate.
Another option is to use something like Jquery and a Javascript timer to count down and then refresh using static page Methods (http://encosia.com has examples).
