JQuery In UpdatePanel Wrapper For PageRequestManager.getInstance().add_endRequest
Mar 18, 2011
When jQuery is applied to elements in an UpdatePanel, when the UpdatePanel refreshes, the jQuery is not applied to the newly injected HTML. This issue is resolved by using
Sys.WebForms.PageRequestManager.getInstance().add_endRequest() to register a function to be called when the AJAX request is complete: I've written a function that registers the function with add_endRequest, and also calls it at the same time:
Async.RegisterAndRun = function(callback) {
//register function to be run when an update panel request is complete
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(callback);
//also run the function right now.
callback();
};
Now all we need to call is Async.RegisterAndRun(AddFancyjQueryToMyHTML); or
Async.RegisterAndRun(function(){
AddFancyjQueryToMyHTML();
AddMoreFancyjQueryToMyHTML('with', 'args');
});
Currently it does what I need it to, and I never need to explicitly call add_endRequest which is nice.
I'm trying to use a DynamicPopulateExtender to add a product to the cart and then report back a success/failure-message to a div. After the request has finished, i'd also like to trigger an update of an UpdatePanel on the page. But there is a problem: To ensure that the div is visible only a short time after the request has finished, and to reload of the UpdatePanel, I need to know when the request has finished - and it seems that the DynamicPopulateControl for some reason doesn't trigger the PageRequestManager EndRequest-event. I've registered for the events with this code, and I've made sure that the code that registers the events run like it should. But neither CartBeginRequest nor CartEndRequest are ever called:
I load an aspx page in iframe inside a jQuery UI dialog to update some data, and after dialog is closed I need to update an updatepanel in parent page. how can I do that? to be more specific, there is a datagrid in parent page and after I edit data in a dialog modal iframe, I want to update the row in datagrid.
I am using multiple user control in my web page. Each of these usercontrol has $(document).ready() method. Because i am using an update panel, i am binding all the events again in end_request event. But I dont want to do that in all my usercontrols. Is is possible to do this at a common place(only once)?
I'm loading a .aspx page via fancybox (ajax loading mode).I was using fancybox 1.2.6, working fine, then upgraded to fancybox 1.3.4 and IE now triggers the JS error above (in the subject of the post). Then why am I posting on ASP.net forum you might ask?!?... read on...Debugging the JS code, the error happens inside jQuery in the .html(data) function where it does a evalScript .each scripts inside data. jQuery version is 1.4.2.I'm able to resolve the problem by editing fancybox-1.3.4.js at line 265. I just use innerHTML to circuvent the evalScript that occurs inside html()... and it works:
//tmp.html( data ); <-- original code commented out where JS error occured var tmpDiv = tmp.get(0); <-- new "plaster" kind-of fix tmpDiv.innerHTML = data; <-- new "plaster" kind-of fix
Why I'm posting on ASP.net and not on jQuery nor fancybox groups is that I consider that the proper fix would be in the .aspx that is loaded via ajax.To summarize the problem. There is a base .aspx page that has a couples of text and buttons. When you click a button, it loads via AJAX a new .aspx page (using fancybox). You end up with two ScriptManager js code and it triggers an error when executing :
in javascript code to get ajax call by updatepanel. I got this code and it worked. Please guide and help me who this server side code (Sys namespace) was used on client side. Why not other namespaced are accessable in javascript ? That is that techniqueetc
Please forgive this ignorant question - I've used ASP.NET AJAX a good deal but I'm new to jQuery. Specifically, is it possible to call or create jQuery events on the fly via an UpdatePanel? For example, calling a jQuery modal or animating a Label (or <div> contained Literal)etcIf anyone has any advice or could point me to some easy tutorials on mixing ASP.NET AJAX and jQuery,
I am getting following error "sys.webforms.pagerequestmanager is null or not an object" in my login page.login page contains script manager tag at start and Ajax CollapsiblePanelExtender n page.
I recently converted my VS 2005 project code to VS 2008.My old code is running fine.
Today we have a windows application that, using an OCX, creates a web page (visible by a WebBrowser control in a small .NET WinForm application) and communicates through COM to the main application/client. (not relevant but this is Pascal)
I'm currently responsible to re create this application in a web environment so we can have the same functionality shared through Web as the user can see the same in a Web Browser.
The Windows application has almost 4 years on it and I need to re create everything from scratch, and all the bugs/features find in the future in the Windows Application I have to re create them again in the Web...
is there any way I can create a Wrapper, even using 3rd party commercial objects, to:
Communicate with the COM Object Can expose the content of the OCX (this in my most confortable language, ASP.NET C#, but other are welcome) I was thinking out loud, can this be accomplish with a Java Applet? Silverlight 4?
have a problem on my application, i am using LightBox javascript that is using prototype.js library, and when i open any pop up that is having script manager it generate this error:Microsoft JScript runtime error: Sys.InvalidOperationException: The PageRequestManager cannot be initialized more than once.I know that is because i have scriptmanager on the parent page that opened the pop up and its something relates to prototype.js but i dont know the connection!
I'm trying to create a SessionManager class which I can use to manage sessions in my MVC applications. For that I'm thinking the best way of doing so is by creating a wrapper class for HttpContext which would then allow me to access HttpContext.Current.Session.
To be honest, I'm not really sure about the whole thing, I just feel it's the logical way of doing so. I also want to create an ISessionManager and ISession interfaces, and then implement them according to my application's needs. For my current project, and for now, I need a InProc session management, but I might need to store session data in MSSQL Server when we decide to expand and use a web farm or a garden. That's why I'm trying to build a sort of an extensible framework right from the start.
Final note, I will be using Microsoft Unity to inject the concrete SessionManager of choice. I believe that's a good way to maintain a certain level of abstraction.
I am getting "Sys.webforms.pagerequestmanager is null or not an object" error when calling the webpage from outlook for some client machines. In some machines it is working fine.
I am executing a SSRS 2008 report from report manager so it opens in a web browser. Since it is a big report it takes some time for execution. During this time i get an error icon on the left bottom of the web browser and the execution stops. When I click open the error icon to see the details it says,
"Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 12029."
The other relatively smaller reports are coming up successfully without any issue.
I am using SQL Server 2008 R2 64 bit ent. edition and the OS is Win Server 2003 64 bit SP 2.
I wrote a webmethod (Called SearchData()) in which the method makes a httpwebrequest to another url and gets the data in xmldocument. After getting the xmlDocument ,it is returned to SearchData method invoker. When i invoke the from browser it works fine. But When another application in java tries to consume this webmethod SearchData(), it is getting the error
<wsdl:part name="Body"/>
and each part should be type defined. The WSDL file is not well formatted. it doesn't have Type defined at each element. How to fix this.or Is there any other Better way to provide the end user the xml(ie from httpwebrequest result in webmethod ) with a soap wrapper ie with a well defined wsdl. My code :
I have a third party dll and i need to add some more functionalities (methods, constants etc..) so create a wrapper class. I have no idea about wrapper classes. what is the purpose of this and how to create in .NET for this 3rd party dll.
I am a REST web service newbie, does visual studio, .NET, or some other nifty microsoft tool provide any easy way to auto generate classes to consume a REST web service? With REST services is there even a service definition like there is with SOAP (WSDL) beyond the printed documentation? There is a new service that I'd like to consume but they only wrote wrappers for PHP, Pearl, Ruby, and Java and have more or less said you are on your own with .NET. I could write it myself but I'd like to cut corners and save time wherever possible.
I've seen how to Fake the SessionState object in MVC using Scott Hanselmans MvcMockHelpers, but I'm dealing with a separate problem.What I like to do is create a wrapper around the Session object to make objects a little more accessible and strongly typed rather than using keys all over. Here is basically what it does:
public class SessionVars{ public SessionVars() {} public string CheckoutEmail { get { return Session[checkoutEmailKey] as string; } set { Session[checkoutEmailKey] = value; } }}
So that I can just do this in my controllers and views:
SessionVars s = new SessionVars();s.CheckoutEmail = "test@tester.com";
Now the problem comes in when I want to write unit tests, this class is tightly coupled with the HttpSessionState. What I can't figure out is what is the right class to accept/pass so that I can pass in a FakeHttpSession into the SessionVars class. I've tried so many things with this, and this (below) will compile, but it can't cast the HttpSessionState into the IDictionary. I've tried ICollection, HttpSessionStateBase.
public class SessionVars{ public SessionVars() : this(HttpContext.Current.Session) { } public SessionVars(ICollection session) { Session = (IDictionary<string, object>)session; } public IDictionary<string, object> Session { get; [code]...
I'm missing something big here. I feel like this is possible and that I should even be that far off.Furthermore, I'm confused as to whether I should use the IHttpSessionState, HttpSessionStateBase or the HttpSessionStateWrapper. What is the abstract type that I'd use for the session object inside my SessionVars class? What is the type that I pass into the constructor?
I have a asp.net page with two jquery button.All is in an updatepanel. When I click on Jquery button all work but after all stops to work.This is code of one button:
does anyone know if its possible to replace the updatepanel in asp.net ajax toolkit with some kind of jquery?
Basically we use the update panel so that when we do postbacks that the screen doesn't actually do a full refresh .. just the values ..
I am using jquery for a lot of other stuff and would love to know if there is some way to do this or even if a jquery plugin exists that lets you do it.
I am a bit unsure but would this mean i have to rename all my methods to static and decorate with the webmethod attribute?
If this is the case, it maybe a lot of work :-)
And of course how would Page_Load execute if it was a static webmethod?
I am just trying to figure something out. At work we have alot of data access code Ex:
[Code]....
Pretty standard stuff really, but I was at a training course recently where the Developers insisted on wrapping code, that seemed nothing more than expose exactly the same functionality.
I was interested in your thoughts as to whether this was a good idea. So the above would inherit from a DbHelper class with some thing like:
[Code]....
These would just expose the same but maybe a bit more generic i.e. using DbCommand as opposed to SqlCommand.
