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?

View 2 RepliesWhy 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#.
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.

View 2 RepliesI 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 am having a base class which implements some basic authentication for all the pages in the application.

I am developing a custom control that needs it's viewstate to be loaded on init. Can I antecipate the view state loading at any time?
View 1 RepliesThe 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.
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:

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 ???

View 2 Replies1) 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).
View 4 RepliesI 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?
View 7 RepliesI'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.

View 1 RepliesI am trying to build a custom composite control, which allows me to add custom content to each child control. It's a similar concept to what you have with a GridView and TemplateColumn. The markup used to place the control on the page would end up being something like this:
[Code]....
I have the code below, which allows me to put that markup on the page without throwing any errors, and it renders all the correct HTML, except it doesn't render the contents of the ColumnTemplate. I have replaced the Render() code with a comment because it's quite long winded and doesn't add anything important here:

I have tried to follow examples on MSDN and other forums but I can't make this work. I think I'm missing the code to render the contents of the template, but I don't know how to hook that up.

I am creating a composite control. On the selection of item in the dropdownlist, the result should be shown. But its mismatching the result. Here is the code for the control:
[Code]....
If I have a breakpoint on the selection index changed event of the dropdownlist, then on every selection it should go to the event. Problem is when I select an item which makes the "singlelineText" textbox to appear and after it I select any other item, it doesn't stop at the dropdown event instead it goes to the "CreateChildControls" method of the composite control which results in wrong data.
I made a composite control that contains a ListBox. I am using the Composite Control throughout my application but I can not bind the listbox in the Compositecontrol. I have setup a Public get to access my listbox in the composite control.
View 3 RepliesI am trying to make a PhoneNumber Control. I inherit from Composite Control. It contains 5 controls : 1 Label (Text to show before), 3 TextBoxes(area, prefix and line) and a Custom Validator. What I want to happen is the validator to validate the control is belongs to in two ways: 1. that the field is required and 2. That the COMBINED text of the 3 textboxes is 10 digits. I believe i can accomplish this with the expression ^d{10}$. Now I have it about halfway working, it will validate the control using client-side
embeded validation on a submit click, however I need the control to validate as soon as the text of any of the boxes changes. I know this is done on the aspx page by using a Custom Validator -> specifying client and server side validation functions -> and then at end of page doing ValidatorHookupControlID(control, va lidator). My goal is to do all of this within the control to clean aspx code and make it more reusable.
