Getting A Scriptmanager Into A Dynamically Rendered Page?

Apr 13, 2010

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.

C# - ScriptManager When Trying To Email Rendered Contents Of Page?

Mar 24, 2010

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();

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:

<input type="hidden" name="ctl00$SCManager" id="ctl00_SCManager" />

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.

Web Forms :: Getting IDs Of Dynamically Rendered Text Boxes

Feb 20, 2010

I have a page that allows users to upload photos and when they click the upload button it renders a few textboxes used to change the photo's information and also the displays the photo. After they are done upload photos, they can then insert all the information in each of the textboxes. Then users click the Upload button and it takes all the information and places it in the database. The problem is that when I say "get the text from these textboxes" using the textbox IDs, it tells me that those textbox IDs are not in the current context.

Here is my code...

AJAX :: Dynamically Added LinkButton Not Getting Href Rendered

Feb 19, 2010

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.

AJAX :: How To Dynamically Add ScriptManager To A WebUserControl

Feb 9, 2010

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:

protected override void OnInit(EventArgs e)

AJAX :: UserControl With ScriptManager And UpdatePanel, Some Pages With ScriptManager?

Feb 8, 2011

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?

Loading ScriptManager Only Once Either From Master Page Or Content Page?

Sep 6, 2010

I have an web application of 200 web pages and all has a single master page. Most of the content pages use AJAX controls so most of content pages has its own ScriptManager. Now I have a requirement to add a link with HoverMenuExtender control and for that I need to put ScriptManager in the Master page, but it is working only in the content pages where there is not ScriptManager.

All the other content pages which has ScriptManager throws the error Only one instance of a ScriptManager can be added to the page. I don't want to work on most of the content pages again to remove ScriptManager. Is there any easy way to do this something like coding in Master page which decides if there is already ScriptManager already, then don't load it.

JQuery :: Hide Page Before It Is Rendered?

Feb 7, 2011

I have a few controls (a panel containing some textboxes and dropdownlists) that are hidden until the user clicks a button to toggle their visibility. The toggling is done via JQuery and works great. One thing that bothers me is that although this panel is hidden when the page finishes loading, you can see it while the load/render process is taking place. So you can see it and then all of a sudden it fades out. Is there a way to hide it earlier in the process so we don't see it at all? I did try putting visible = "false" on the panel definition, and then you can't see the panel on loading which is good, but then my JQuery code won't toggle it to visible. Perhaps my JQuery code needs tweaking.

Exporting Rendered Html Page To Word

Mar 17, 2011

I have a rendered html page which i am exporting to MS-word and downloading on a button click.
The code snippet in the button click.

Me.EnableViewState = False
Response.ContentType = "application/vnd.ms-word"
Response.AddHeader("Content-Disposition", "attachments;filename=XXXXXXX.doc")
Response.Buffer = True
Response.BufferOutput = True

The functionality works perfectly well in FireFox & IE when i checked in system testing envirenment(locally).However when in was moved on to hosting server(production environment) the functionality is not working in IE , however it is working perfectly in FireFox.

I am not sure on where to check the exact issue for.Will it be any caching related problem?.

In IE it is just not opening the download window which we will obtain when the rendered html content type is changed and response stream flushed.No exception is thrown.

I received the following response header :

HTTP/1.0 200 OK
Cache-Control: private
Content-Length: 15189
Content-Type: application/vnd.ms-word;

C# - Page Not Rendered When Sending Statuscode 500 To The Client

Jul 20, 2010

I have a page (generic handler) on which I want to return the status code 500 to the client to indicate that something is wrong. I do it like this:

Response.StatusCode = 500;
Response.StatusDescription = "Internal Server Error";

And at the same time I render a friendly message telling the user that something went wrong. But instead of seing my message, I get the default IIS message saying something like this:

Server Error
500 - Internal server error.
There is a problem with the resource you are looking for, and it cannot be displayed.

And if I go in to IIS and remove the error page for 500, I get this message:

The page cannot be displayed because an internal server error has occurred.

It works as intended in IIS6, but not in IIS7. What should I do to get it working in IIS7?

How To Get The Current ScriptManager Without Page

Jan 14, 2011

I'm trying to extend ScriptManager to simplify dealing with resources that have multiple resource files (e.g. more than one script file as well as css). The goal is that I will be able to add a single ScriptReference to Scripts and have it load more than one resource related to that reference name.

What I'm getting stuck on is, how does your basic ScriptManager know what to do with stuff when when using static methods that do not include a Page parameter? For example:

ScriptManager.ScriptResourceMapping.AddDefinition("someName", new
ScriptResourceDefinition { Path="/script/somescript.js"});

This adds a definition to (I guess) whatever the active script manager is for the page that's running when you call it. But unlike the old-school methods, like RegisterClientScriptBlock there is no parameter passed that identifies the page. But this stuff must get stored in the ScriptManager object, no? So how does it know?

I could always get a reference to the active one with this:

ScriptManager.GetCurrent(page);

but ideally, I would create new methods that work exactly like Microsoft's. I can't figure out how I could implement something like

ScriptManager.ScriptResourceMapping.AddDefinition(string name,
ScriptResourceDefinition definition,
ResourceType type)

that could figure out the object instance to add the stuff into without having to add a Page parameter.

AJAX :: ScriptManager Not Found On The Page (although It Is On Page)?

Feb 3, 2011

I've upgraded my web application from ASP.NET 2.0 framework to 3.5. I've also updated AJAX toolkit from 2.0 to 3.5. The updated was made on 20th of January.

However today the application started giving me error that there is no ScriptManager on the page although it's (I'm using AJAX ModalPopupExtender on 2 pages). I didn't change anything on the pages except yesterday I've added one ASCX control to both pages but problem doesn't disappear even if I remove the control.

Basically the thing stopped working for no particular reason. I will try to reinstall the AJAX toolkit and I think that there are maybe somethings to change in web config but it's strange since it worked perfectly until few hours ago.

C# - HTML Form Tag Isn't Being Generated When Page Is Rendered In Firefox

Aug 3, 2010

I developed a basic web page in MVC 2 for learning the framework, and I am stuck in this situation:

I have 3 classes: Client - Product - New. And for all need to display a modal popup to create/edit action. For display the modal i used JQuery and jqModal plug-in.

I created the controllers for all objects, the views for Index action, and Delete action. For the Create/Edit Action I created a partial view named ModalBox. Inside this partial view, I have an Ajax.BeginForm, and it calls another partial, that represent the form of the objects.

This works very fine, ... for the project object! in FireFox 3.6, for others object's the form tag is missing...

Web Forms :: Showing Temporary UI To User Before Page Is Rendered?

Feb 24, 2010

In the ASP.NET application that I'm working on, the home/landing page takes around 20-25 seconds to load.

And, that is expectable by everyone, as the application loads huge data, calls multiple services before the first page can be loaded.

I am looking to show some kind of HTML UI to the user while the page loads up.

I tried multiple things but the earliest that something shows up on the page is through Response.Write() in the Page Init and hide that HTML content in jQuery's $(document).ready(). In this case also, something shows up after 60% or the wait time has passed.

I want something to show up as soon as the authentication is done (form the login page) and before the home page shows up. Something similar to what shows up on Orbitz.com or [URL], some kind of UI between clicking search and the actual search result is shown.

If it was ASP.NET MVC, I can think of good solutions as you have complete control on the rendering but we are using ASP.NET 3.5 with server side Ajax controls.

Here's what currently takes place before the home page:

Login page submit actions -
Authenticate,
Load SSO Data,
Redirect to home Page.

Using ScriptManager / UpdatePanel In Content Page

Aug 21, 2011

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?
