View 2 RepliesI'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 ???
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#.
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 1 Replieswhere is session state, application state in page life cycle?
View 2 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 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 am having a base class which implements some basic authentication for all the pages in the application.
public class BasePage : Page
{
public void Page_PreLoad(object sender, EventArgs e)
{
if (!IsUserValid())
{
Response.Redirect("default.aspx");

View 1 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).

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.

View 1 RepliesI am currently using a asp.net 2.0 with visual studio 2005.
I am trying to build a web application using ajax.
but when I drag the ajax updatepanel on asp.net page it is not resizable,so how should i put other controls on it?
i am using a TabContainer and at each TabPanel i have embed an UpdatePanel in order to update each tab alone.
this is my code:
[Code]....
the problem is that it makes several seconds to update each tab (the same time for every tab) and i asume that this is happening because it updates all the TabContainer and not the selected Tab.
I have two updatepanels on my site (upanProfileSearch and upanMemberList). When I hit the button in the upanProfileSearch it should bind the Data Items in the gridview in upanMemberList and here make a RowFilter on the text in upanProfileSearch. When I make a run to curser, I can see, it happens. It makes a RowFilter. but it doesn't update the gridview. Can anyone tell me why it doesn't update? I have UpdateMode="Always" and RenderMode="inline" on both UpdatePanels.

I have a dropdownlist, that causes a postback. On the SelectedIndexChanged event, is it possible to force a placeholder that is within a different UpdatePanel to change it's visibility?
For example, when the SelectedItem.Value of DropDownList1 is "1" then show Placeholder1, otherwise hide it.
What I am most interested in is how to configure the UpdatePanels to allow this.

I have a web user control with one updatepanel (pnlUpdate_2), some controls and one apply button. I display the web user control as a modalpopup in my default page. In my default page i have an updatepanel (pnlUpdate_1) with a gridview and I modify that gridview with the apply button of the web user control. The web user control is for made a custom search of the gridview data. I have a problem with both updatepanels. If I set the updatemode as always in one of them (pnlUpdate_1) and the other as conditional (pnlUpdate_2), the pnlUpdate_1 make a postback in the pnlUpdate_2; I'm not an expert on this but I think that's why the pnlUpdate_2 disappear and reappear after postback of some controls in that updatepanel (not the apply button, it close the modal after postback). I try all the combinations and the problem persists. So I put both updatepanels as conditional and in some way it works; now the problem is that when I click the apply button in pnlUpdate_2 to modify the gridview in pnlUpdate_1 the pnlUpdate_1 not made the postback I get the pnlUpdate_2 postback when I use some control inside the pnlUpdate_1.
How can I postback the pnlUpdate1 from pnlUpdate_2 with the apply button?
