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.
View 1 RepliesFrom my testing, it appears that the order of parameters for the UpdateParameters must match both the order of the bound fields on the form (asp:Formview), and the order of the parameters in the UpdateCommand. Is that correct? If so, why do the parameters have names if all that matters is the order? I tried both asp:ControlParameter and asp:Parameter. Maybe the more relevant question is why aren't the names used instead of the order, particularly for the form order?
So, given I display the Identity field (CID), and need that for the update, I cannot get the update to work without including it in the UpdateCommand. Of course, since it is an autonumber field in Access, I cannot actually set it. So, I had to add another field to the db (lngUpdateCID) that I could set. That can't be how it has to be done, but I could not figure out another way to do this.
The relevant code is below:

I have to display data (names) in a random order on the website. The data is stored in a MS Access database. The names must be displayed in a GridView and DataList in different places. I have created a query in MS Access "zorder: Rnd([MarinaAccommodation]![ID])" which works fine in MS Access giving me a different order each time.
The problem is that when I try run it on the website the order remains the same, it does not change each time the page is loaded.

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?

MSDN documentation says that the ScriptManager class is part of the System.Web.UI namespace and I see that I can create a ScriptManager object programmatically. However, I don't see the ScriptManager control on the front-end. Do I need to reference the Ajax Control Toolkit dll in order to have access to control?
View 6 RepliesI 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?
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 want to access the session value at client side.
Code:
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
btnGetSessionValue.Attributes.Add("onclick", "javascript:return GetSessionValue();");
}
}

I've my ASP.Net HTML 5 Application, Which have the image byte array in Session, I'm using the Latest 5.X C# facebook SDK from CodePlex.
But when user is authorized and Coming back to my canvas page at that time I can't access my ASP.Net Session, its give me a null value.
Here is my Code.

Now pls give me some suggestion, Where I'm missing, How can I access my Application Session.
I have 2 projects in my solution.
MVC Web application
Class library
The MVC Web application references the class library.
The class library contains a class that extends the default ASP.Net Controller.
I'm putting a variable in session in the application's Global.asax.
protected void Session_Start(object sender, EventArgs args)
{
HttpContext.Current.Session["DomainName"] = Request.Url.Host;
}
In the class library I'm trying to get the value from the HttpContext.Session, but HttpContext.Session keeps coming up null.
[code]...
HttpContext.Current.Session doesn't seem to be an option in controllers.
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.
while(int progress = DoWork() && progress <= 100 ){
Session["Progress"] = progress;
}
and my handler just return Session value.
context.Response.Write(Session["progress"].toString());
context.Response.End();
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?

"Now one option if you want to have your DLL pull the stuff from Session is to abstract out session. So you could define an interface like IStorage, that your library will know how to use. Then you can have a SessionStorage or MemoryStorage class and use IoC to inject the appropiate class into your library classes. This gives you the freedom to code it how you wanted it to be coded without tying your code to Session. Oh and one other benefit if done properly can be used to not tie your code to session in the web either.
