Need Updatepanel And Scriptmanager Get AJAX Working?
Dec 13, 2010
I'm finding that the scriptmanager and the updatepanel and basic implementations of AJAX for ASP.NET. I'm just wondering whether these were required to use AJAX and partial page update and referencing handlers such as button1_click on the server code page ?
Also if i can ask another question, I'm also wanting to know whether the updatepanel can support feed-in like facebook ? What I'm wanting to do is have something that updates the screen (like the update panel), and items within this panel contains links. When the user clicks on the link it shows a modal div, giving the user options to do some updates. Once the user clicks submit, then this makes a call to the server to update the details then also update the panel. Within the panel I also want to move some of the div elements using javascript (causing the drag and drops to save to the database).

I have a user control with both an UpdatePanel and a ScriptManager.
Some pages in the system have a ScriptManager of their own, and need to include the UserControl.
This throws the "You can only have 1 ScriptManager" exception.
If I remove UserControl's ScriptManager, I'll get 'UpdatePanel1 requires a Script Manager" exception.
I've tried to modify the UserControl to dynamically include it's own script manager if none exists. But all the methods I've used before involve adding a delegate to Page.OnInit-- which won't work, since the UserControl Init fires first.
Because the system designers here like making my life difficult, I can't create a MasterPage, or a BasePage for the system in inherit off of. I'd be stuck going to each page an adding a ScriptManager before the UserControl on each of them. Is there any way of, in the UserControl, detecting if the page has a ScriptManager, and if not, adding it dynamically in a way that makes the UpdatePanel happy?

We have a ASP.NEt 4.0 project i just started. For some reason the ScriptManager, UpdatePanel and ListView controls have 0 intellisense, give me element not found errors and are really starting to $@#% me off. in 3.5 everything works fine. BUt in 4.0 none of these controls work (although they all exist in the toolbox). I do NOT have any Ajaxcontrol Toolkits installed for any previous version of ASp.NEt. I DO have the proper System.Web.Extensions dll referenced and it does exist.
My web.config is TINY though (is this new to 4.0?) i noted that in my compilation tag all i have is :
<
compilation
debug="true"
targetFramework="4.0"
/>
wheres in 3.5 in this were loads of references to the assemblies. Do i need this? I uninstalled and re=installed VS 2010 2 tiems today and its still the same.

I have a page with a ScriptManager / UpdatePanel. I currently need to PostBack to a https page from an http page (different ports). I also need the same session data. Currently, I copy my form to a new form, and when I postback to my new Target on a new Port, I get a crash in xmlHttp..something. I will have to post more details later.
I'm currently wondering if this is possible. And does anyone know of such a fix. I even tried to Turn off Partial Rendering and I still get crashes. I can't do this until I pull out the scriptManager / UpdatePanel.

I have a small website that uses 1 masterpage and several content pages. I'm able to insert a <ScriptManager> onto my content pages (just a couple of them). However, when I try to insert the <UpdatePanel>, it won't take it. I tried to wrap the <UpdatePanel> around a <Div> and it didn't like that, so then I tried wrapping the <UpdatePanel> around the actual textbox and it didn't like that. Below is some sample code.
Code:
<%@ Page Title="" Language="vb" AutoEventWireup="false" MasterPageFile="~/Site1.Master" CodeBehind="Profile.aspx.vb" Inherits="PF.Profile" %>
<asp:Content ID="Content3" ContentPlaceHolderID="contentProfile" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
<div class="ProfileDIV" style="width: 48%;">
[Code]....
How can I incorporate the <ScriptManager>/<UpdatePanel> onto my content pages?

I have a simple aspx page created using VS2010, having a master and a content page. I have added the ScriptManager from AJAXControlToolkit on the master page and an update panel on the content page. Essentially clicking a link button should display a popup box through the PopupControlExtender. The issue I am facing is that eventhough I have AJAXified the page, clicking the Linkbutton (named lnkFlag) doesn't do partial update, instead it makes full page postback. This could be infered by the fact that both the lblOut and lblIn labels are updated with the server's time. If there is a partial page postback then lblOut should not be updated, since it is outside the UpdatePanel.

In my application, I am using different user control for different tasks. I used an update panel to load user controls with ajax. It is working fine. I am using some other update panels inside the user controls. My problem is, the inner update panel(UpdatePanel placed inside the user control) is not working properly.

We are currently migrating the client part of a legacy webapp from asp.net ajax to jquery/jquery-ui. The app consists (among other things) of some asp.net ajax UpdatePanels.
Now I want to throw out all that __doPostback() stuff and talk with jQuery's $.ajax to the "server-side" of the .ascx controls. Ideally, the server reponds with some parseable Datastructure that I can throw into my jQuery UI controls.
I already realized that this is difficult to do, because the asp.net ajax client/server code is heavily interwoven and there are no public interfaces to hook into ajax requests or responses. However, we don't want to change the server-side code, because it should still run with the old asp.net frontend.
After some tweaking I found out that I can hook into ScriptManager's beforeRequest and endRequest events to get notified of postbacks and partial responses. I dispatch these to jQuery Events:
var paqeRequestInst = window.Sys.WebForms.PageRequestManager.getInstance();
//bind ASP.NET ScriptManager events to jQuery events
paqeRequestInst._events.addHandler('beforeRequest', function(){
$(window).trigger('beforePanelResponse');
});
paqeRequestInst._events.addHandler('endRequest', function(pageRequestInst, ErrInst){
$(window).trigger('afterPanelResponse', [pageRequestInst, ErrInst]);
});
However, a lot of questions remain:
What is the best way to intercept the ScriptManager Response, parse it, and throw it into my jQuery UI controls? How do I update all that __VIEWSTATE stuff, that is normally managed by the ScriptManager?
Are there best-practices/jquery-plugins for such a "asp.net ajax to jquery" scenario?

I have a panel (say, panel1) inside another panel (say, outer-panel)….The panel1 is visible only when a checkbox is checked in the outer-panel. I am using ajax update panel to do this.
Now I have many text boxes in the panel1. I have to put a validation on all the boxes.
I tried to test this by putting validation on 2 boxes and this works fine on my local machine. When I put the same logic on the server, it does not. Of course the page on my local machine has fewer text boxes compared to the page on server. But I do not understand why the same logic works on my local machine and does not work on the server. I did try to put a validation group, but of no use.The page on the sever is a very long one and also it has a captcha control….. when ever I try not to enter text in one the text boxes which has validation and then hit submit…it redirects me to another page with out prompting for the validation error.

I am building a website using ASP.net ajax. there are 3 <asp:panel> controls in the page and each contains a number of dynamic linkbuttons. these panels are contained in a <asp:updatepanel> control the page_load event fills out the first panel with linkbuttons and assigns cooresponding commandName commandArgument for them, that works. then the first panel's linkbuttons triggers the command and fill out the second panel with linkbuttons, that works too. then the seond panel's linkbuttons are supposed to fill out the third panel with linkbuttons, but that doesn't work anymore, and it seems like doing the page_load event again and filling out the first panel and the second panel's linkbuttons disppear, just like the first time the page is loaded.

I have a Submit button and some functionality like updating DB and fetching next page in the button click event. This process takes a long time and I want to display a message saying "Progress...." right after clicking the botton. I want to do the same in 20 other pages. So, best way to do it wd be to put the modalpopup MPE or an Updateprogress in a usercontrol or in master page. I first tried putting both of these on the page itself to test and see and neither worked.
I tried using Update progress control with a dummy updatepanel and giving the Submit button as Asyntrigger to the dummy updatepanel. I have also tried using MPE but it didnt work either. Below is an example of what i did..
<asp:UpdatePanel ID="UpdatePanel1" runat=server><contenttemplate><triggers><asyntrigger ID= "Submit"> /> /> />
<asp:updateprogress ID="Progress1" unat=server AssociatedUpdatePanelID="UpdatePanel1"><Progresstemplate>Progress.... />/>
<asp:button ID= "Submit" runat=server >
I have nothing for updateprogress in code behind. Am i missing or doing somethign wrong here?

We have an updatepanel in our site and there are a number of linkbuttons in it. Please note that the site works fine in all browsers without proxy the proxy changes the url from for instance [URL] to 0-[URL] it also works fine in all browsers but IE the issue is that under proxy and in IE8, it gives an error when clicking one of the linkbuttons, the error message is "Webpage error details User Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; Tablet PC 2.0; InfoPath.1; .NET4.0C; .NET4.0E) Timestamp: Sun, 13 Mar 2011 20:38:58 UTC
