I have a pagemethod defined with the attribute [WebMethod]. The pagemethod accesses the session with no problem (HttpContext.Current.Session).
However I just read somewhere that in order to access the session in a WebMethod, you need to define it like so: [WebMethod(EnableSession=true)]
So my question is, what gives? How come I can access the session even though I dont have that code? Apparently EnableSession defaults to false if its missing, so I should not be able to access the session. The web application uses ASP.NET 3.5 and uses InProc Cookieless sessions.
I have a custom class library that performs validation. I want to open up this class for use within Javascript. I understand that I can easily achieve this by utilizing WebServices/WCF or by creating a function on my page with the WebMethod attribute, but it'd be nice not to have to set all that up for every project.
Ideally I'd like to just add the WebMethod attribute to my class library methods and then call them using Javascript.
By using AJAX am trying to call a webmethod in Code behind. In that webmethod I want to put some dynamic grid data and text box data to session. But WEBMETHOD is static, so we wont get access to Session and web controls. Is there any other method to achieve that goal.in window.onbeforeunload calling a script, that script calls a webmethod. This is the procedure i am following.
my Requirement is: when user clicks on search button ,i need to call a ajax post method from client side and have to access the request.querystring(to get some info of logged customer) in static web method?
Tried things:
1.unable to access the request.querystring in static web method
2.saving the request.qerystring data into viewstate/hidden filed,but unable to access non static fileds in static method?

i m using Gridview which contents images.Every time user uploads images that images are get inserted into gridview .That is on button click event i m binding grid. But by doing so , every time when user clicks button page is get refreshed. So to avoid this i used WebMethod in which i m trying to bind gridview , but as Webmethod is always static i m not able to access gridview. So my Question is can we access Gridview inside static web method.If No Why?
when I access the webservices URL through browser ,I am able to access the URL ,If i use the webmethod in c# code the error message is diplaying like "The Requested Failed with HTTP Status 404:Not found".
I have a service that works great on my development box. It uses JQuery to hit my web service, and then the JSON results are sent back.
The web service is located on our basePage.cs. We didn't want to put out an external WebService for this. Our on beta box something different is happening.
The web page seems to be trying to call the web method correctly - the JSON data is being sent... but the server doesn't seem to know it's a webmethod. here's my service function (it's in our basepage.cs which inherits from Page).
I have the following two pages. One is a search page that have a few listbox/textbox/and dropdownlist. The other will be the result page that take from session those 3 data and using an if/else statement to sort out some detail. After that it will form an access/sql selectcommand to search the database base on that 3 criteria. But for some weird reason only the first part of my if and else statement work. Can anyone check and help me out why the rest of the if/else doesn't work. Or point me to another direction?
I am trying to get into grips with AJAX/JQuery and MVC. i need to access the session on the controller. This doesnt seem to be initialised at the constructor level but there needs to be a way I can store items in the session in the constructor depending on the parameter values (an extra constructor is written here) I am also doing unit testing here, which has been provided by 3rd party and they are using this extra constructor.
So the idea here is that when the page is loaded, JQuery will request a collection of items (which will be stored in session) and also be able to post to the page so items are added into the collection too. So, what is the best way here to get access to the session in the constructor of a controller?
in one request i am updating session variable. in the other request, i am trying to access that session value, but it was blocked until the first request finish. I am using C# with ASP.NET 2.0 UPDATE: My page code looks like this.
I'm building a Javascript application and eash user has an individual UserSession. The application makes a bunch of Ajax calls. Each Ajax call needs access to a single UserSession object for the user.
Each Ajax call needs a UserSession object.
Data in the UserSession object is unique to each user.
Originally, during each Ajax call I would create a new UserSession object and it's data members were stored in the ASP.NET Session. However, I found that the UserSession object was being instantiated a lot. To minimize the construction of the UserSession object, I wrapped it in a Singleton pattern and sychronized access to it.
I believe that the synchronization is happening application wide, however I only need it to happen per user. I saw a post here that says the ASP.NET cache is synchronized, however the time between creating the object and inserting it into the cache another Thread could start construction it's another object and insert it into the cache.
Here is the way I'm currently synchronizing access to the object. Is there a better way than using "lock"... should be be locking on the HttpContext.Session object?
I'm trying to use the HttpContext.Current.RewritePath method to serve up different versions of an application to different customers. I would love to be able to look at the HttpContext.Current.Session object to know who it is making the request. Oddly when I go to look at this at the BeginRequest handler, the Session always shows null. I've tried various other events and have had no luck.
in my web app users login to website normally and they have tagged in user table in database as online user in Session_End i want to log them outIn Session_End i have no access to HttpContext.Current.Session or Session only they are both null how can i access to session variable at (Session_End) event.
I want to access the user session from a web method. But when I check for the session object, its nothing! How can I access the current user's session from the webmethod?
I am putting together a small database for recording stock movement.I have a table which will hold
StockID StockItem QtyInStrock
