Architecture :: Object Life Cycle - What Is The Order Of Events?
Jan 13, 2010
I'm trying to better understand the life cycle of an object in the .Net framework. My companies Intranet has some custom classes that were written by a vendor that I'm trying to make some modifications to. Specifically I want to set some variables & hashtables to null when use of the object is done. For now I have this in the dispose event.
Is there any info you can point to that would be good reading on the life cycle of an object in the .Net framework? I.e. what order do the events fire in? OnInit, Initialize, finalize Dispose, etc. I have the ASP.net page lifecycle but I'm not looking for that.

1) I know there are lots of web sites that describe in what order events are called during the Asp.Net page life-cycle. But is there also a tool, perhaps Reflector, that would enable me to figure out by myself in what order are ALL the page's events and their event handlers called during the page's life cycle? 2) Would you say that trying to figure out exactly what is going on under the hood is a good idea or a waste of time? To clarify - I'd like to figure out exactly what is going on when a control tree is build - thus all the method calls, all the events called etc needed for control tree to be build ( I imagine there are hundreds or perhaps thousands lines of code written just for building a control tree).

Why class name and method name dropdown list is not similiar to vb in c# code behind.
Say for example I am getting all the events for page in vb.net, But I am not getting same as vb.net in c# while I am trying write code for page life cycle events in c#.

The situation:
I have user controls with buttons that have hooked events. Controls with events need to be initialized in Page_Load or earlier.
I wish to spawn these user controls dynamically by clicking an Add button.
It is important to remember that events, such as click events, are not fired until just before Page_LoadComplete.
Broken Solution A:
[code]...
Result: Everything works great, except the button within the added user control is inert.
The conundrum is: I need controls to spawned by a button click, which means I need to put my Controls.Add(...) code in Page_LoadComplete. Inversely, I need the controls being added to have working events, which means the Controls.Add(...) code need to be in Page_Load. I have a perfect dichotomy.

We are creating a composite server control. It will have few other controls. I am confused where exactly to write the code ie in which event. Is page life cycle and control life cycle follow the same event order?

I'm a completly noob in Multi-Threading c# web pages... and i'm taking the first steps... I have one web page that create one new thread for each image to load. Each thread only read the external image and save it to local server. I have for example pages that have 25 images... that page loads but it launchs 25 thread (1 for each image).
The code:
[Code]....
I assumed that when a thread finish it's job it will automaticaly be killed, is it that way ?? I'm asking because, when i try this code on the server, after some navegation and multiple images loaded the IIS goes down and the page return "Service Unavailable" error :( To solved it i need to restart the IIS Application Pool... For those that have experience in multi-threading web pages how can i kill this threads ? Aren't they suposed to be killed when their job is finish ? ? Do you know a good tutorial or article for begginers ???

Apparently I am not familiar with the Life Cycle of a page in ASP.NET. This became apparent when I wanted to dispose of a Session variable after I left the page. I did what made the most sense:What I didn't know is that this would be called when I go from AND to the page. What I am wanting to do is dispose of that Session variable whenever the user leaves the page.

I am writing a web application that takes in session variables from the user and when the user comes back to the page the form elements are automatically filled with the users entery. So I tried using the page_load event to check to see if the session object was equal to null. But then when I rerun the application the form elements are filled in with the previous entery. Does this mean that if a user logs into the system and has a session withing the lifetime of a previous session that the form elements will be filled in with the previous data?

I want to share a common page load and page init events sequence between Master page and child page and User Control as described below:
Let us have the following components:-
1. TestMaster.master -> It is the master page
2. TestChild.aspx -> It is the Child page
3. TestUserContrl.ascx -> It is the UserControl present within the TestMaster.master page.

I've posted the same question in the Object Data Source forum. This is a link to it http://forums.asp.net/t/1554083.aspx. Maybe I should've posted here to begin with. There seemed to be some overlap so I wasn't sure which was the best on to post the question in.
I'm trying to get a better understanding of how I could've designed my app so that the Object Data Source could work with the properties of my business objects. Please read the other post to see how it's currently being done. Sorry for the link to the other page. I didn't want to post a bunch of duplicate information. I would love to get some suggestions for alternative ways of doing this.

I want to make sure my theory of an upcoming project will work. Online ordering form for a restuarant. Order will be for pickup or delivery. no payment online. so gather order information and call web service which lives on a computer at the restaurant, this web service will log the order information into a file then send the order information to a ticket printer in the kitchen.

I am building an ecommerce site and I struggle to find a way to check the stock levels for each order.I have created an "in house" procedure that involves the administrator having to push a "check stock" button for each item on the order but it doesn'tlook too elegant.
