I am new to asp.net. I need to know the difference between the following 2 methods :
1. double clicking the button placing the code
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)

I work in VS 2008. Whenver I add a server control(Label) and set it properties in aspx.vb and build the solution, I get the error "Label1 not declared". While analyzing this issue I noticed that the event handler statements for the Label1 where not added in the designer.asp.vb file. These statement would actually be added automatically when I drag and drop a control to my webpage.
I would also like to inform the scenario after which this problem came to me. I was working in VS 2008 , VS 2005 and VS 2003 in the same machine.Could this have caused the issue ?
Now each and everytime when I add a control, I am adding the "With Events" code in the designer page to make my build succesfull which makes me to spend more efforts.
I have a login.ascx control with three controls (LoginName, Password and A Button) , I want to rase a click event on this button from .aspx page because some restriction is there so that I am unable to write any code on .ascx page.
I have assigned value on login name and password from .aspx onload events. but I an facing problem while rasing event on button.
I am showing code that I have written on .aspx page that I have putten onload section.

We have recently put up a new server with IIS7, where we now have published a .NET4 site.
Locally everything works fine, but on this server the Default.aspx is not working. No events are firing at all for this page. Every other page works as should.
We've tried deleting the Default.aspx and adding a new blank one with just a button event but same thing still applies.
We've spent quite some time troubleshooting this without any results. Same problem exists both with and without using a masterpage.
I'm new to ASP.NET, and I came across these two different extensions while browsing around. What's the difference between them?
View 2 RepliesI have an aspx webpage in which an user control is added dynamically as follows:
UserControl testUsrControl = LoadControl("TestUsrControl") as UserControl;
testUsrControl.ID ="test";
Then I tried adding an event handler of user control inside aspx like below:
testUsrControl.Drpdatafield_SelectIndexChanged += new EventHandler(this.Drpdatafield_SelectIndexChanged);
But this line is giving error at **testUsrControl.Drpdatafield_SelectIndexChanged **. The error is "Drpdatafield_SelectIndexChanged" doesn't exist in UserControl.How can get the testUsrControl's events inside aspx page dynamically.
I'm trying to use a third-party ActiveX control on our intranet ASP.NET site, and I've run into a problem I can't figure out.
Expected behavior: The control expects to see a specific variable in the URL ("msg"). If you provide it, it works. If you don't provide it, it complains that the value is missing.
If I put the control in an HTML page, it works fine. But if I then change the page's type to aspx, the control acts as if the variable isn't there. The control still loads and runs; I'm not getting any permission or safety messages. But it complains that "msg" wasn't provided on the URL.
In other words, if I try these URLs, the first one works fine; the second one gives me the "you didn't provide the msg parameter" complaint:
(works fine)
http://mysite.mydomain.com/controltest/test.html?msg=123
(complains)
http://mysite.mydomain.com/controltest/test.aspx?msg=123
I know the aspx version is being processed by the server before being sent to the client, but there aren't any server-side commands or tags (it's the same file, just copied and renamed). As far as I can tell, the resulting page that is sent to the client is exactly the same.
Is there something about aspx vs html that would cause the control to not be able to get that variable? I can see it fine from javascript that I add myself. Here's the content of the page. Not much to it. If I get this working I intend to add some aspx tags and code, but there's no point yet.
<html>
<head>
<title>
ActiveX Control Test

</head>
<body>
<OBJECT ID="control1" CLASSID="..." CODEBASE="..." >

I put common code in the app_code directory. I access classes in the code all the time from aspx.cs files by "using" the name space from the C# file in app_code and then referencing the class. Now I want to access a class from an app_code file a aspx file. How do I do this?
View 8 RepliesI was thinking about the performance when I use code to hide some control in aspx page using delimiters or in cs file. For e.g. If I have a panel and I want it to get shown following some condition, so I can achieve this by two ways
1: Using code in aspx file, something like this
<% if(isAllowed) { %>
<asp:Panel ...></asp:Panel>
<% } %>
2: In the code file, something like this
<asp:Panel ID="pnlMyPanel" Visible="false"></asp:Panel>
And in cs file
if(isAllowed)
pnlMyPanel.Visible=true;
In my view, first way should be good as it will not at all create any Panel in the page. Am I correct here?

I am writing an appointment form that has search date textboxes: startdate and enddate with a search button.
(in file date.aspx)
<asp: textbox id="sdate" runat="server"></asp:textbox><asp:textbox id="edate" runat="server"></asp:textbox>
<asp:button id="btn_search" onclick="btn_search_Click" />
(in file date.aspx.cs)
void btn_search_Click() {
---in here i can list all the dates based on the input in date.aspx
---output like saturday, 1/1/2010 open
sunday, 1/2/2010 office close
monday, 1/3/2010 open
}
However, i want the output like this to be displayed in date.aspx. So for each date i can have different time schedule.
Like
search dates: [textbox sdate] to [textbox edate]
[button search]
saturday, 1/1/2010
[time table1]
sunday, 1/2/2010 office close
monday, 1/3/3010
[time table 2]

i would like to know if there's a combo like jCryption (jCryption) - PHP but for jQuery - ASPX.I mean, I have been searching for a combo to send data both ways (Client-server, server-client) with jQuery to ASPX. The best I found was jCryption that sends data from JavaScrpit to PHP. I need a combo to send data from JavaScrpit to ASPX.
PD: Please don't tell me to use HTTPS, it's not enough to ensure the data communication on a client - server application.
I have an aspx application with 2 aspx pages. Second aspx page will get opened on click of a button in first aspx page using JavaScript. The problem is, when the second aspx page is getting opened, its Page_load event is not firing. Only when I refresh the second page, page_load event of second aspx page is fired. what might be the problem and what is to be done to fire the page_load event.
View 1 RepliesI wrote a test page that does a bunch of busy work in a method called at page load. This process as I have it now takes around 12 seconds.
If I try to load another page while the first long running page is loading, this second page doing nothing except writing out a world, it doesn't load until the first long running page is finished.
Why is this the case? I would think IIS would be able to handle multiple concurrent connections, it seems crazy that one long running page would stop every other page in the application from loading. I must be missing something or not understand how IIS works.
I would think multiple independent requests would be spawned on different threads. Is this only the case if the requests are from different sessions entirely? Are all requests from a single session bound to a single thread?

I have done a web appllication and when run simultaneously from different locations, the one that is started first would use the one that is started late's session variable and datatable contents. This is an exams web app and pageone.aspx results should never be used for pagetwo.aspx's results, because they are not the same questions.
What can I do to prevent this from happening. I am desperate, people are standing by to do exams and time is not on my side.

First of all, thank you for the attention.
I am having some trouble, I am very new to asp.net, and the last problem I had, I spent about 59 hours trying to solve, Now I have a new one !
:D well, I guess this is part of the learning process...
Well, in Visual Studio 2010, I clicked New Website. @ C# language, ... The template it gives is pretty nice, it creates a database MDF file, and a login/register setup ready to go !...
You guys can see it live AT CLICK HERE ...
Everything is working, well at least here at the local machine...
There are 2 pages in there, Default.aspX, and About.aspx ... I want to allow ONLY logged in users to view those 2 pages... I tryed a few things, added my account to a role called ADMIN,
In the web.cong I changed Allow"*" to allow"ADMIN" ... still didn't work.. Also, I was trying to avoid using roles for now, and I was trying to find a way to do this for individual pages in the same directory as well... If possible with out touching the web.config file...
