MVC :: Clear Session Object In The View?
Mar 5, 2010
have been a great resource for me since i am new to MVC and trying to learn and figure out few things.My chain of thoughts still might be asp.net, so here is another question.I have a session object in my controller action which i use to populate my view , i need to clear the session object everytime i navigate out of the page (more like a session kill in page unload event). I really appreciate any ideas and inputs on how and where to clear the session object

Is there a difference between Session.Clear() and Session.RemoveAll()? The descriptions and documentation pages seem to say exactly the same thing, but I am assuming there must be some reason for creating two functions, right?

I need to clear all sessions at the end of my application, to many to list individually.
So I have found the following ways, but which is best?
Session.Clear();
Session.Abandon();
Session.RemoveAll();
And then the specific way
Session.Remove("variable");

I am caching a file in ttpContext.Current.Application object. Now when I change the values in file, it does not get reflected in the application (I am reading the values from the file for app version).
Even after restarting the app pool and the website in IIS, the changes does not reflect. I dont want to restart IIS.

I have just added the following to the very last page of my application.
[Code]....
And then i have this on each of the pages before the last, within my Page_load:
[Code]....
I have different sessions thruout the application process, but this one session is only set at the beginning of the process and once i kill it on the last page, any attempt to hit Back or trying to access any page directly without first starting, i need to force them to the beginning, what am i missing or doing wrong?
sessID is set on page 1 and is available until you get to the last page. Where i added the Session.Abandon(); Now if i get to the last page and hit back before the refresh occurs, im able to go back, but the page comes up with null reference for other sessions that are obvisously cleared / killed with the abandon. So i should have to check for each session should i? I mean if the abandon killed them all, then checking for the main session should be enough right?

I have a report parameter page which contains many pop up windows for the parameter selection. For example, for driver , there is a pop up window called driver.aspx which contains a listbox that contains list of driver's name.
Now, for each of these pop up windows, i am passing the values of these windows as a session value.
Now, when a user logs in the system, there are many parameter pages for different reports which commonly share the same pop up windows if the parameters are same for different reports.
The problem now is,a user selects 10 drivers for report 1 and runs it. When he goes to report 2 and runs the report, the report 2 takes only those 10 drivers as the driver parameter value.
It means, the error can arise on the system because he may forgot that he have selected 10 drivers for previous report 1. User will not have time to recheck each previous selected values of different paramaters.
What i want is, when a person moves from one report page to another, i want to clear all the session values and adjust it as default for the new report .

In the VS2005 environment, when I test my session to make sure the page redirects to the main page (itself) if the session is null, it works. There is no error.
The function I use for this is:
[code]....
However, when it is in the production environment in IIS 6.0, when the session has timed out, and I then do a postback by doing some slider control, I see the page reload but immediately thereafter, it throws a Server Error exception of : Object reference not set to an instance of object.
Looking at the stack trace, the event occured:
AJAXEnabledWebApplication1._Default.Slider1_TextChanged(Object sender, EventArgs e)
however, why is it that the Slider1_TextChanged event fired even even after during page_load, the page was told to do a response.direct ?? shouldn't the entire page have gone through a full-page refresh life cycle ? why did it continue on to attempt to raise the Slider1_TextChanged event?

I am confused about how to reference objects in session, how to update, and copy.
if I create
MyObject obj = new Object ();
then
Session["object"] = obj;
MyObject temp = (MyObject)Session["object"];
If i change something on temp, will the object in session be updated? do i need to follow changes with Session["object"] = temp?

I want to be able to persist data across a session but do this outside of the built-in session state object. Why is a long story that I will not go into here. I just need to know where I can put data other than in the session object that will persist across the specific session.

I have an entity object as model input in my view. Not sure if it's the best approach, but I use the object references to get values from a related object.Let's say I've got a car entity and a manufacturer entity.Here's how it would look in my view
[Code]....
I've get a nullreferenceexception where the car entitity does not have a reference towards manufacturer. I'd like to output a " " if no manufacturer exists.
