AJAX :: ScriptManager Input Tag Not Rendered With XHTML Strict Compliance?
Jul 15, 2010
I seem to have come upon an issue with XHTML 1.0 Strict compliance and ASP.NET AJAX. When a ScriptManager is included on the MasterPage, it renders the following tag:
In order to be XHTML Strict compliant, this tag must be included in a <div>, as is the VIEWSTATE. Even when Strict compliance is enabled in the web.config, the ScriptManager insists on rendering in a non-compliant way. This is currently blocking our transition to Strict mode, as it's the only non-validating tag on our pages.
We are rendering usercontrols dynamically like this:
[Code]....
This lets us the same user controls when rendering pages normally as we do when rendering responses to ajax calls. However, when adding controls which themselves contain a scriptmanagerProxy we run into the problem that the newed up Page object doesn't contain either a ScriptManager or the HtmlForm in which the ScriptManager needs to run.
I recently added a Telerik control to an ascx that is included in an aspx page. This page has a "Send email" button, which when clicked will email the user the rendered output of the page. The Telerik control I added requires a ScriptManager, so I added that to the ascx. However, now the email button won't work. I get the following error:
The control with ID 'myIdHere' requires a ScriptManager on the page. The ScriptManager must appear before any controls that need it.I know the script manager exists because the page works fine when I go that url, it is only failing when it tries to email the rendered output.Here's a code snippet, any ideas as to whether there is a problem with scriptmanager when doing this sort of thing?
Page EmailPage = new EmailBasePage(); System.Web.UI.HtmlControls.HtmlForm EmailForm = new System.Web.UI.HtmlControls.HtmlForm();
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?
I want to make a flower shop using the technologies mentioned in the title. I was thinking about customer/admin login in ajax. I'm using Visual Web Developer 2008 Express and I know a bit of VB.
Anyone know of a turnkey replacement for the asp menu control that is css compliant. That is, in a browser like the new IE8, you don't have to run in compatability view to have work. I am aware of work arounds like setting z-index etc and Context.Request.Browser.Adapters.Clear for other browsers like Safari but just wonder if there is a clean databound menu control that will work with all css complaint browsers with no need for patch
I am assigned to create a credit card application that follow PCI Compliance. I know that there are documenation in PCI Compliance website about what kind of thing need to be followed. Is there anybody has somekind of sample code about ASP.NET Credit Card Processing?
My Tab Container works fine on my development machine. But it doesn't show up my production machine. On closer inspection, the Production machine renders it as hidden. Any thoughts on why this would happen?
Im using a web form that contains a button(having id=btnSubmit) dropdownlist(having id='ddlDynamic') and a panel which has a dynamicpopulateextender that makes use of the fllg webservice method
Here is (more) code that demonstrates the issue. If the control in the host page is removed the tab control renders correctly. Otherwise it is rendered with the visibility attrubute set to hidden as reported in the above link. Is this broken or am I doing something wrong?
I have a user control that needs a javascript function so I put my JS code in a variable and used the ScriptManager.RegisterStartupScript in Page_PreRender of the control as follows
I have a form which I am using the RoundedCornersExtender, If I am using the ScriptManager control I am getting the following error-Error: AjaxControlToolkit requires ASP.NET Ajax 4.0 scripts. Ensure the correct version of the scripts are referenced. If you are using an ASP.NET ScriptManager, switch to the ToolkitScriptManager in AjaxControlToolkit.dll.I googled it and found that one way to overcome this is to use the ToolkitScripyManager, I replaced the ScriptManager with the ToolkitScriptManager and I dont get the above error anymore. On this same form I am using an UpdatePanel control but from some reason I am not getting a partial render but always a full page render.

I'm having a serious problem with my ASP.NET AJAX application.There is an javascript function in my application needs to be executed after the Timer_Tick event. Here's the code behind:
[Code]....
When I call the javascript function 'UpdateValue' for the first time(at onload page event), it works correctly. But after the Timer_Tick event, it does nothing. This is the HTML code:
[Code]....
What's the problem with the ScriptManager or the Timer_Tick event?
I am trying to update a listbox on the server from javascript using Ajax PageMethods. How would I reference the listbox control inside the Shared Sub, I get Error 156 Cannot refer to an instance member of a class from within a shared method or shared member initializer without an explicit instance of the class. The reason I want to do it this way is because when I updated it on the client the code-behind did not have the updated count.
way to detect from the server-side which DOCTYPE the page is specified as. I have some HTML and CSS in a custom WebControl that renders differently depending on which DOCTYPE the page is. Is there a Page property or a Response property I could check?
There seem to be about a zillion posts on similar situations, but I can't seem to find an answer in any of them. I've tried numerous techniques that I've seen, but nothing is making a difference. I have a Master page with an UpdatePanel with a ContentPlaceholder. In the content page I have a calendar. Above the calendar are LinkButtons that trigger a Command event to switch between Day Week and Month views. In the calendar DayRender event I am adding items to each day of the calendar. Items are pulled from a database. All items are contain within a dynamically generated div to help with layout. Each event that is added is a hyperlink that takes the user to a page where they can edit details of the event.
If there are more than 4 events, I'm adding a LinkButton with the text, "(more...)". I'd like that to trigger a Command event so that I can switch to the Day view of the appropriate day:
[Code]....
The problem is that, while the anchor tag gets generated with the proper text and ID, no href attribute is rendered and, as a result, nothing happens when you click "(more...)". I've tried switching to a Click event, but it does the same thing. (And I need the Command event to use the code I already have in place for some other buttons.) I've tried rendering it as an asp:Hyperlink and using ClientScript.GetPostBackClientHyperlink. That gives me a hyperlink, but I don't know how to get it to trigger so it results in the server interpreting it as a Command event and linking it to the proper event handler.
I have downloaded the latest version of AJAX toolkit (AjaxControlToolkit.Binary.NET35) and add to asp web page as I did many times before without any particular problem. However this time I'm experiencing unwanted results that make me want to through the computer into my neighbor's pool. The tab control is rendered with the following inline style:
I had this problem: I created a WebUserControl that used som Ajax stuff - hence it needed a ScriptManager.
The problem was that I couldn't add it to the WebUserControls html code (the .ascx file) since the WebUserControl sometimes was placed into a parent page that already had a ScriptManager, and I couldn't add a ScriptManagerProxy since the parent page sometimes didn't had a ScriptManager.
Alot of people just use a ScriptManager on the MasterPage, but this fails if: one doesn't use a MasterPage or one uses iFrames etc. that uses stand alone aspx pages, like Thickbox might do...
Here's the solution:
in the WebUserControls code behind (.cs file), put this:
I just downloaded the latest (3.5.40412.0) version of Ajax Control Toolkit and in order to update the existing version, I have replaced <asp:ScriptManager with <ajaxtoolkit:ToolkitScriptManager. The page loads with an javascript error:

Can anybody explain why cant you have more than one scriptmanager control in a page. Why gets emitted in the markup which creates a problem with two scriptmanager control on the page.
