Loading Web Application Content Through AJAX?
Oct 26, 2010
I'm about to build a web application(not web presentation) which will load its content through AJAX (jQuery) into a specific div. There will be a menu above the div and when a user clicks on an item from the menu, the appropriate page will be loaded into the main div.I'd like to know if there are any cons and pros of choosing this pattern for a web application.So far I'm avare that the browser back button and history/url will be gone.

I have an ASP.NET MVC view. I want the view to load and then do a post using ajax to load some secondary content. I know the Ajax.ActionLink methods etc. but I want the post to happen automatically when the page is loaded. And not based on some user action.

I have a website where I'm trying to use an HTMLEditor to allow users to alter the body of email text. The text is stored in a database and looks like this:
[Code]....
I load the current email body into the Content property of a new HTMLEditor.Editor object. When it loads the HTML, though, it looks like it does above; it doesn't "process" it. Can the Editor process the HTML?
Also, when I do edit HTML in the object and submit, the Editor's Content includes "<" instead of "<", etc. Do I have to manually deal with that?

I have 2 Imagebuttons on a nested Masterpage. When I click one button I want load a content page and change the image of the clicked button to show that it was selected. Loading the content page goes okay but I can't seem to programmically change the image of the button. I have been reading the posts on the life cycles of MasterPages and Content pages and I think I have the code in the correct page but it is not working. I am so confused now.

Is that any multiview alternative? I am doing a project that have to load the data in to a content space. Right now I am using the multiview provide by asp + using ajax.net. but it seem like very heavy when I load that page. So is that have any alternative to doing this? I have a concept that like using the load php funtion calling~is that applyable in asp.net? I am new in coding~ the effect I want to do is just like the user profile page on [URL] by clicking the button list change it content without reload the whole page.

Old hand at ASP.NET, new to the UpdatePanel. I have a reporting page which executes a fairly length SQL query... takes about 10 seconds right now. What I would like to do is have my page fully render, with some placeholder text (Loading...) and then have the UpdatePanel kick off the actual time-consuming reporting process and render the report when it's done.
So... my theory is to use RegisterStartupScript() to kick this off and drop the string from GetPostBackEventReference() to trigger the UpdatePanel update. Some problems crop up:
1) Can I actually use GetPostBackEventReference w/ the UpdatePanel or do I need to trigger it some other way? Use this method on a button inside the Update Panel?
2) What event gets triggered when the postback reference is the UpdatePanel? It's not clear to me. I've got to call my databinding code somewhere! Again, maybe I need to use a button inside?

I am building a website in which all of the site layout is in Master page and the content of the site is in the inherited pages. I have various links for navigation in which i simple use Response.Redirect to transfer to different pages. Now the problem is that I want to put the content place holder inside Ajax Update panel so that the postbacks are Asynchronous and I want to show the postback by an animated image inside Update Panel progress control. The problem is that I am unable to achieve this result and the entire page is posted back and rendered again. I have placed the content place holder inside the Ajax control toolkit's Update panel but it does not work. Is there any way that I can change the content of the content place holder to a new page with asynchronous postback.

the situation is quite complex ( and my english very basic) but let's try to explain:
i'm developing a Asp.net web service calling a method from an external dll. This external dll calls some method from other .net dlls. So we have:
Asp.net WS ----> External.dll ----> other.NEt.Dll(---> other .netdll)
You have to know that the external dll uses a path ( given by an initialize method) to resolve its internal reference. In conclusion i have a web application with an added reference to my External.dll and a fully trusted path ( c:EXTERNAL ) full of all the .net dlls needed by external.dll. Looking around i've found this code to add to the application_START:
Dim path As String = String.Concat(System.Environment.GetEnvironmentVariable("PATH"), ";", "c:EXTERNAL)
System.Environment.SetEnvironmentVariable("PATH", path, EnvironmentVariableTarget.Machine)
this add my c:EXTERNAL to global environment PATH. With this configuration running from the Visual Studio development server i get no error and it all works correctly. When i publish the application on my local IIS server it gives various errors: At first the result is something like:
Failure reading <Myobject> control of <(static)> type
Unable to create <myobject> object (<C:(WRONGPATH)
eeded.net.dll> assembly)
To resolve this i've tried to add the needed .net dlls to the /bin of my application in wwwroot but the result is something like:
Failure reading <MyType> control of <Myobject> type
Error returned by .NET Framework:
System.ArgumentException: Un oggetto di tipo 'ComNet.BaseControl.LoginDisplayLayout' non può essere convertito nel tipo 'ComNet.BaseControl.LoginDisplayLayout'.
in System.RuntimeType.CheckValue(Object value, Binder binder, CultureInfo culture, BindingFlags invokeAttr)

in CDotNetType.bSetProperty(CDotNetType* , Object gcrObj, SByte* pszNom, CSLevel* pclPile, Int32 nDimension, Int32* pnTabDimension, STOperationDotNet* pstOperation)
this time it looks like it's loading the same dll but from different location causing conflicts. Now that's all. Its hard for me to explain this dll-hell but basically i would like to replicate whats happening when the application works well in the visual studio development server. I've also read that IIS does not resolve Added PATH without rebooting so i tried to add c:external manually to the PATH and reboot but same errors appears.

I have a site where I am trying to implement a jQuery UI based MessageBox in my master page. Content pages are arranged accoring to business area folders, i.e. '~/Branding/Contracts.aspx'. I find that when I load such a content page, jQuery, which is referenced in the master page as below, does not load. I assume that this is because the browser is requesting 'Branding/Scripts/jQuery What can I do about this? I don't have the 'root' operator in a plain 'script' tag.
<script src="/Scripts/jquery-1.3.2.js" type="text/javascript"></script>
<script src="Scripts/jquery-1.3.2.js" type="text/javascript"></script>
<script src="Scripts/jquery-ui-1.7.2.custom.min.js" type="text/javascript"></script>

I am trying to create my own website management framework similar to DNN/SiteFinity (only a mucho cut down version).
One of the big (but common) features is to be able to dynamically add user controls to provide additional functionality.
I would prefer to use a pre-compiled .NET "Web Application" over a dynamically compiled "Website".
What are the implications of using LoadControl method to dynamically add a user control for a pre-compiled web applications with specific regard to:
Session (preume I am using the stateserver)What happens to all the other users - will they be logged out?
Application pool recycling due to changes to some compilation??
I am not sure I have ever dynamically added a user control to a pre-compiled web applications as I have mainly been using "Websites" so I am making a large presumption that it will work because if the website is pre-compiled, does this mean the dynamically added user control will be dynamically compiled as required even though the site is pre-compiled?
EDIT
I also forgot to mention that the user controls will be outside of the application directory and so won't be published during web deploy - they will be uploaded via another website.

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.

At present we are using <ajax:TabContainer> to load tabs. I have 5 user controls inside <ajax:TabPanel>.
The problem is that all the data on these 5 pages gets loaded at once and increases the loading time as well as it is very hard to debug. Can we do lazy loading uisng TabContainer control? so that only the data of the current tab is loaded and when we click on the other tab then that's control data gets loaded.
