I am using the MultiView server control in one web page using Update Panel. In its second view, I have a GridView; whose first column is checkboc controls including the header.
I want to toggle the data items checkbox based on the header checkbox.
For this, I wrote a Jquery function. But the main issue is, When I try to view the page source, I was not able to find out the HTML for the second view.
How could I toggle the checkbox using Jquery or Javascript?
The reason you can't see the HTML source is that the MultiView is a ASP.NET server control and it only renders the currently selected view to the browser.
Use FireBug. After you toggle the view and the HTML is updated, you'll see the current source so you can debug the jQuery.

i am at starter level in asp.net i was developing a small application just to add students to database, main reason was to use update panel but when I use AsyncPostBack trigger the dropdown box does not render properly but with normal PostBack it does I am assuming i am missing out something the code has nothing special i just used and inside and here is an image that can describe it better
here is a link screenshot of what's happening : http://imageshack.us/photo/my-images/842/dfpw.png/
Are you using any Jquery plugin to make normal dropdownlist as fancy as looking in the screenshot attached.. if that is the case call the same plugin in the pageLoad() function too as after partial postback happens, the dropdown looses it's appearance and looking like normal dropdownlist.
I have asp.net application and a TabContainer from AjaxControlToolkit on a form. There are 4 tabs, each containing UpdatePanel, hidden button and some custom .ascx (each with it's own javascript file). Buttons are triggers for panels to update the contents and they are triggered from the 'OnClientActiveTabChanged' event of the TabContainer.
This technique is described here and similiar here. It's pretty simple when looking at it.
The only problem I have is that the whole scenario works when used as a separate page but it doesn't seem to work when masterpage is around that page. Suddenly buttons act as full postback controls.
Do you have any idea what's the reason?
Assuming the buttons your referring to are on the master page, I think you'll want to register the master page buttons as update panel triggers.

I have three views inside a Multiview
How to activate one by one view means I Just want to change the Active View Index of the Multiview using javascript in ClientSide How can i do this?
I dont think you will be able to without causing a post back as the multiview is a server side control and only the active view is rendered to the browser.
You probably need to have all the views on the page and all but one hidden. Are you implementing some time of tab control?
There is a tab control in the ajax control toolkit which switches between views clientside:

I'm developing an ASP.NET 3.5 web application using C# with AjaxToolkKit. I have a following question.
How can I put a collapsible panel inside GridView to make a master and detail list that expands to display the detail panel when view link in a row is clicked? This is something similar to the download list in MSDN page.
Thanks
Implement jQuery on the page. Have a look at the ajax methods, specifically in your case the load method. Show the master record on the page, along with a hidden div (you could inject it, but hey lets keep this simple ;). Bind the load to the click event of the master record displayed, and then use slideDown to show the hidden div on the page.
ie A very simply example of the load method, loading the html result from ajax/test.html into the element that is selected by 'result'
$('#result').load('ajax/test.html');
I have a ListView on a page that displays a list of widgets. When a user clicks on one of the items in the list, I want to display a ModalPopup that contains controls allowing the user to operate on the item they selected.
I could easily accomplish this by placing a Panel and a ModalPopupExtender in the ListView's ItemTemplate, but this mean one set of hidden controls for each and every widget, which would massively bloat the page size. (There are going to be some rather heavyweight controls in there.) Instead I want to reuse a single ModalPopup for each of the widgets in the list.
I've done some searching but I haven't found anything that applies directly to my situation before. From what I've been able to figure out, however, I have to do something like this:
Place a Panel and a ModalPopupExtender on the page inside an UpdatePanel.
Build a custom WidgetManipulator user control that has a WidgetID property. Put this in the Panel, along with a couple OK/Cancel buttons.
In Javascript on the page, attach a click handler to each widget in the ListView that triggers a postback on the UpdatePanel.
On the UpdatePanel_Load event on the server, display the ModalPopup and then set the WidgetID propety on the WidgetManipulator to the ID of the clicked widget.
On the OKButton_Click event or CancelButton_Click event on the server, hide the ModalPopup. If OKButton was clicked, call WidgetManipulator.SaveChanges() first.
The part I haven't figured out is: How the heck do I know what widget was clicked on, and how do I pass that back to the server when I refresh the UpdatePanel? Is this even the right approach at all?
If you can use jQuery instead you could do something along the lines of these two posts:
Modal Delete Confirmation Version
Two Using jQuery SimpleModal Plugin

When I need to pass data from client to server in ASP.NET AJAX, I generally use an asp:HiddenField with runat="server". Both can see it freely, but beware potential postback asynchronicity.
Sounds like you need to notify the server the widget was clicked - You may use a Timer to postback; or I'd go with option 5.
