View 4 RepliesI have an update panel in a user control and I am adding multiple instances of it for example 5.
When that update panel refreshes the page load occurs 5 times.
How can I prevent it only for once?
It works when i pass the querystring on the browser as this: http://localhost:51765/foo/foo.aspx?ID=c516f4f4-36a9-40a7-baad-d2419ea631b9 want it to work when the page load not when i pass the querystring on the browser.

I want a browser to go full screen as soon as my page loads. Is it possible in javascript. I know the shortcut key for this F11 but requirement is on page load only.
After reading the solution provided below. I achieved full screen but here i got a trap. I was using timer to make my page postback to get fresh data after every 5 second. And here I found after every 5 sec new window opens up but I want full screen to go only once and next time content gets refreshed there itself.
I have an existing asp.net web application I am redesigning to use a service architecture. I have the beginnings of an WCF service which I am able to call and perform functions with no problems. As far as updating data, it all makes sense. For example, I have a button that says Submit Order, it sends the data to the service, which does the processing.
Here's my concern: If I have an ASP.NET page that shows me a list of orders (View Orders page), and at the top I have a bunch of drop down lists for order types, and other search criteria which is populated by querying different tables from the database (lookup tables, etc). I am hoping to eventually completely decouple the web application from the DB, and use data contracts to pass information between the BLL, the SOA, and the web app. With that said, how can I reduce the # of WCF calls needed to load my "View Orders" page? I would need to make 1 call get the list of orders, and 1 call for each drop down list, etc because those are populated by individual functions in my BLL.
Is it good architecture to create a web service method that returns back a specialized data contract that consists of everything you would need to display a View Orders page, in 1 shot? Something like this pseudocode:
public class ViewOrderPageDTO
{
public OrderDTO[] Orders { get; set; }[code].....
Or is it better practice in the page_load event to make 5 or 6 or even 15 individual calls to the SOA to get the data needed to load the page? Therefore, bypassing the need for specialized wcf methods or DTO's that conglomerate other DTO?
I have four repeaters, that are all independent to each other. They all bind via web services on page load and then display the results.
There is a noticeable delay however and I would like to know how to achieve the following if possible.
On page load I want to begin asynchronously binding the repeaters so that as soon as the first one is bound, its result display and then the next starts binding.
I looked at update panels but from what I have read they do not have a page load trigger.
am using a master page, with children pages.
I am using forms authentication, and a session object to hold user information once the user is authenticated.
I am able to login and log out. I am able to log in and use the "remember me" functionality of the forms authentication.
When attempting to test the "remember me" functionality, the master page load event contains code to check the forms authentication & remember me, and retrieve user info from the database to automatically log the user in. This fires correctly, and the screens all load with the user successfuly logged in, and the users info is successfully stored in a session object.
Without touching anything on the screen, a moment passes and then the master page load event spontaneously fires again, Page.User.Identity.Name still contains the user name, however the session variable is now null, and throws an error.If I tell it to run past this error, it does, and the application continues to function normally, withthe session variables set correctly.
Its almost as if that second firing is ina different session, or something.
I have no problem posting code, but I have a profile class holding / handling the session communication, etc so it is a bit cumbersome.
My requirement/concern is to test web application locally in multiple browsers with various versions.
If any tool is available, please let me know..

View 3 RepliesI really like coding in VB and i have built a few windows forms and messed around a bit so recently i dove into the web forms and website coding aspect of my VB 2010 studio. i watched a the tutorials and i've been all over this forum but i can't get my webpage to load in my browser. the top line of code, that comes with the default ASP.NET website:
<%@
Page
Title="Home Page"
Language="VB"
MasterPageFile="~/Site.Master"
AutoEventWireup="false"
CodeFile="Default.aspx.vb"
Inherits="_Default"

I've found that some of my ASP.Net web apps prompt the browser to load plugins that I'm not explicitely using and certainly haven't deliberately referenced in the project settings.Two that come to mind are for MS MediaPlayer and the "SVG Viewer for Netscape".The only commonality I've determined so far is that the two sites/apps affected both use Master pages (nested in some cases).We don't use SVG file types (just the normal mix of jpg/gif/png) and no video/audio (not yet anyway).Can anyone provide a hint as to where the references for these might be creeping in? e.g. Is it a server-level include? Or a .Net runtime default when using master pages?Does anyone else even experience this, or is it just me?

I have a update panel on the ASPX page,When thepage loads the content in the update panel shouldnot load ( Update panel should show the Updatepanel progress control) but after page load update panel contents should load . How do i get this efect.
View 3 Replieswe are creating a custom content management and out portal page is bit bulky it is about 60Kb without images.
and during loading the page in some browser we can see some parts of site load faster than the other parts of the site where as we want to indicate (or instruct the web server) to load some of the areas first then load rest of the page.
is there any particular setting in IIS for is there any particular method in classic asp for doing that?
also I have the same question in asp.net.
I'm developing my first Facebook application in ASP.NET 2.0 and doing a simplest thing, that is, to show a navigation on top with four hyperlinks where each link targets to another .aspx page. How can I do this using FBML in ASP.NET 2.0?
Otherwise coming to my question, where I'm struck after trying above thing at myself and failed then had to go around the Ajax way of doing this. Now I'm using Ajax call over the onclick event of each hyperlink from top navigation and it's succesfully loading external .aspx pages (for example,[URL]. The problem is when user comes on the application on first time, it only shows the .aspx page which has a navigation and a Ajax content place holder which is programmed to be filled with contents on click event.
How to load Ajax contents into the Ajax content place holder on page load without a click event?
how i can load an panel(that contain for example Weather information) after page load
View 2 RepliesI am using a third party gateway. The third party gateway does not support query-string , so i will need to post the form to pass the values to the given URL and another thing is that they don't expose the web-services so we need to use their page and that means we need to host it in an iframe in asp.net
so what i did is that i have hidden fields that will be used as parameters as depicted below
Code:
<input type="hidden" name="p1" value='4635' />
<input type="hidden" name="p2" value='Reference_test' />
<input type="hidden" name="p3" value='Purchase credits' />
[Code]..
Now the purpose of this , is to load the iframe after the page load event of the asp.net gets fired.
Now my problem here is that when the iframe loads , it does not pass the parameters to the url that is being set in the iframe.
I have attached the example, project. (2kb)
When you run the project you will notice when the iframe loads there is an Error
"NO VCS ID"
now this means that the parameters were not passed when the Iframe loads , i can understand because it seems like iframe does not do a full form post. so to demonstrate what i want, click the proceed button and you will notice it will give you a page with no errors and it will be a page where credit card details are required , i want to iframe to load that the first time.
I would like to seek your suggestion for the tool faciliate the multiple-browser testing of web site. ASP.NET is my current working environment.
View 6 RepliesI am facing performance problem on my asp.net page.
So I want to load some of the contols after page loaded properly.
Is this possible using ajax.
So its a ASP.NET problem where two users using the same machine, same browser:
User 1 logs in the domain.
User 1 changes some data without saving it.
User 2 logs in the domain in a separate tab.
User 1 switches back to his tab and saves the data.
User 1 actually saved the data into User 2!!
This is caused by the following mechanism:
Different tabs in the same browser seems to share the same session id.
We are storing user auth in cookie and the cookie is shared between tabs (same domain)
Therefore, when User 1 request to save, it is recognized as User 2 since the cookie has been updated to User 2.
So I'm wondering if there's any other methods to prevent this from happening, other than:
1. Use cookieless session so the session is embedded in uri.
2. Always include a hidden field in page to indicate which user owns the page.
I am sorry if this is been discussed earlier. I am having a problem maintaining the session when someone uses the same browser with multiple tab, the results gets messed up. A perfect example would be, [URL] if you open IE (or any other browser) and open two tabs and search for two different air travel itinerary and the results will completely overlapped (real mess). I know the cause for this problem (both tabs uses the same session). I would appreciate if somebody have any solution for this. I am using ASP.NET 3.5/VS 2008/VB.NETI will not be able to use Viewstate since I use a master page and pre-init event where view state is not available.
View 2 RepliesI have ASP.net application that is basically a data entry screen for a physical inspection process. The users want to be able to have multiple browser windows open and enter data from multiple inspections concurrently. At first I was using cookie based sessions, and obviously this blew up.I switched to using cookie-less sessions, which stores the session in the URL and in testing this seemed to resolve the problem. Each browser window/tab had a different session ID, and data entered in one did not clobber data entered in the other.
However my users are more efficient at breaking things than I expected and it seems that they're still managing to get the same session between browsers sometimes. I think that they're copying/pasting the address from one tab to the other in order to open the application, but I haven't been able to verify this yet (they're at another location so I can't easily ask them).Other than telling them don't copy and paste, or convince them to only enter one at a time, how can I prevent this situation from occurring?
