I can remember reading something on this in a book but I can't remember. How do you ensure that certain graphics have been loaded to the users computer before any of the page is rendered?

Does anyone know a good tutorial to add a loading image to your webpage while the content is being rendered/created...
View 4 RepliesI've been working in asp.net webforms and I've been making a UserControl that depends on a small bit of javascript which is in an external file.
I want to be able to put a reference to the javascript inside the UserControl to ensure that it gets loaded on the page, but the problem is that the UserControl can appear multiple times on a page so I only want the script to be loaded with the first instance of the UserControl.
Is there an easy way to do this in ASP.NET Webforms?
I am developing a web applications. The application was intially done in Visual studio 2003 using csharp. then it was upgraded to visual stduio 2008. Now there is one webpage with 3 files with following extentions (.aspx,.aspx.cs,.aspx.resx) I right clicked on file to convert it web application but it is just the same. The main problems I have with this file as follows;
When I put a text control on form (.aspx) it is compiling with out any error but when I want to use the same control on aspx.cs it is not being recognised. How can I slove this problem?
Second when I do changes on aspx.cs file there not being recognised although there is no error when I compile.
I have a summary page that has an Add New Record button, andEdit Record butto and a Delete Record button.Every user has ReadOnly access.However, only users with administrators Access Level can add, edit, delete, view.Users with Staffers Access Level can only Add records but cannot delete or edit.So, basically, 2 access Levels, Administrators, Staffers.Administrators can view, add, delete, update records.The rest, Staffers, can only view and Add records.I am struggling to figure this out.I have done this a ton of times using Classic ASP, something like:
If AccessLevel <> "Administrator" Then
Response.Redirect"login.asp" 'so if user has admin password, s/he ccan log in with that.
End if
[code]...
4 different groups will be using the system, each will be redirected to their own summary page based on their groupNumber.All I just want now is to ensure that a user from a particular group is redirected to his/her summary page, then that user is checked again against AccessLevel (view, edit, delete, update).
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.

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 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;

I am working with .net c#. Is there a way to see the rendered html code under the updatepanel?
more info:
I dynamically generate UI controls and place them in a asp:Panel control I have under updatePanel. My page is initially almost empty, and I add about 50 new controls upon button click. However, I cannot see the html code generated in the page source. as in, I can see my textfield on the screen but I cannot see the corresponding code in the html source on my browser.
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?
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 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...
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.
Like I want to check
on Every page <h3> tag must come after <h2> otherwise page should be marked.
like if any page has PDF then Some particular text <p>Download Adobe reader from here</p> should be at bottom of every page is this condition is not matched then page should be marked.
I want to make different type of conditions to check then want to check on whole site and if anything mismatch then report should be generated.

How to Disabling the form elements until the page is rendered completely.
View 1 RepliesWhen user cliick on the control before page fully loaded it goes to error page.
Following is the trace.
Execution Error
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.

View 1 RepliesI have an ASPX page which hosts a Custom Control. That custom control needs to call an ASMX web service. I would use a PageMethod, if the fact that I'm calling from within a Custom Control didn't preclude that. I'm looking for some guidance on the most effective way to try and lock down the ASMX call such that it will only succeed for my users calling it from my ASPX page - and not for anyone trying to call it from elsewhere. I've seen various ideas around session variables and so on.
