View 4 RepliesWeb Forms :: How To Declare A Global Variable That Can Be Used Within A User
May 15, 2010I would like know how to declare a global variable that can be used within a user after the user login and before the user logout across all the possible pages.
I need to develop a web application that will connect to 5 different servers depends on the selection of user on what server they wish to connect and after they select a server and login...I will need to keep track the server name in a variable last until the user logout (user may visit various pages but the server name MUST NOT be changed due to other user login into different server). So how can I do it so that other users may select different servers and will keep the server name for each different users.
Let says:-
User A selects Server A and login and User B selects Server B and login at the same time, so how the global variable can handle the needs for each user (User A & B) with different server select?
Is "Session" the only way to fulfill the above? I think of using Application State but it seems that the value stored will be shared by all users and not for a particular user.

View 5 RepliesState Management :: Looking For A Way to Declare A Global Variable?
May 14, 2010I'm looking for a way to declare a global variable (so all pages could see) but personal (so if one user puts some value in it, it won't matter to another user or change his value).Sessions and hidden fields won't do. I've tried working with declaring keys in Web.config but unfortunely, the keys values aren't personal, and all users share the same key value.Another way I was thinking was maybe classes, but perhaps there might be an easier solution?

Sep 10, 2010I'm using ListView + DataPager + ObjectDataSource mix.
In the implementation of my SelectMethod of an ObjectDataSource I'd like to access a global variable set in the PageLoad() event (the method will return just the proper number of items per page). Although the variable is initialized in PageLoad() it appears to be null in SelectMethod. How can I change that?

Web Forms :: Global Variables, Menus And Post Back?
Jan 8, 2010with a problem im having or at least give me an idea about which direction i should be going in.I have an asax file - with the following void Session_Start(object sender, EventArgs e)in that I am storing a session which holds a boolean.This boolean holds a flag which when set to true tells the application to go to the database and retrieve data, if its set to false, it checks the information in memory.I am using master pages and inside my master page i have and ascx files - which holds my navigation items(I build the navigation menu based on certain criteria)on a content page (a page that uses the master page) I perform a function when a button is clicked and I set the session flag to truethe problem is that the flag is not being checked until i refresh the page twice and therefore the menu is not updating until the user clicks to another page.my suspicion is that it is because of the page life cycle (the event handlers are done AFTER page load) - is there anyway around this?Is there any web page links you have got that I cant google? (yes i have googled but to little luck - maybe im using the wrong search term).on an additional note im trying to avoid like the plague - storing anything in the viewstate

Javascript - Access Global Variables That Are Set Inside An Event Listener?
Dec 18, 2010I am working with Google maps api V3. I need to get the values of the getSouthWest & getNorthEast bounds of my map. To do this the 'bounds_changed' event needs to be fired in order to get the new values. This is all good, however, I need to access these values from outside the event and passed to a server side function (more specifically, I don't want to call my server side function every time the map bounds are changed).
My code is:
//Global
var sw, nw, Searchbounds;
function myFunc(){
google.maps.event.addListener(map, 'bounds_changed', function() {
Searchbounds = map.getBounds();
sw = Searchbounds.getSouthWest();
ne = Searchbounds.getNorthEast();
});
CallServerSideWebService(sw.lat(), ne.lng(), ne.lat(), ne.lng());
}
When executing this code I get the error message sw is undefined.

View 1 RepliesC# - Dictionary Lookup Efficiency & Request Scoped Global Variable Accessible By Global.asax And Pages/etc?
Feb 8, 2011I know there is a couple answered questions on here regarding "request scoped" globals, but I want to nit-pick on something specifically and maybe squeeze some extra enlightenment out of one or two of you.I have an ASP.NET C# Website and a static Dictionary of objects (loaded from DB once on Application start). Each page request will need to do a lookup in the Dictionary (based on a key derived from the request url/etc) and get the appropriate object.The issue is I'm trying to maximize efficiency by reducing the lookups to the Dictionary per Request. Doing just a single lookup within a Page itself is easy enough and I can pass the object to sub controls, etc too.. but global.asax is separate from the Page and it also needs to use the object (in Application_BeginRequest and Session_Start).
So is doing a Dictionary lookup once in Application_BeginRequest, once (when necessary) in Session_Start and once in the Page negligible speed wise, even if there are many requests coming in every second?I would like it if I could just have a Request scoped global variable that I can easily call upon.. the only one I see available though is HttpContext.Current.Items and that is a Dictionary itself.Am I beingridiculously nit-picky with my concern over efficiency? or will these milliseconds (nanoseconds?) get me in the long run when more and more requests are being made?
PS. I currently only have around 100 objects in the Dictionary although this may increase in the future.

Recently i went for the interview where interviewer asked me 2 question which i was not sure for the same..
whats the use of session object, i said sessions are the server side object, they are used when you want to store user specific data at server side, then he asked what if i want to use static variables for the same, i was mum, can anyone tell me how asp.net will behave if i store the user specific information in static variables.If i use cookies which are the best option to store the data at client side (not sensitive one), but what if user has disabled cookies on his machine, will my application would crash.
