In my asp.net web application,I use IFrames to show another page inside one page.But the problem is that the page load event of the embedded page in the IFrame is not firing when the Iframe is shown by clicking on a button in the parent page.I use the IFrame's visibility is true/false to show or hide the Iframe.I am confused what is happening there.

I have created a class in c# inside a class library and i have added this control to the default.aspx, but my code doesnt fire the page_load event. Here is the code:
The page loads but doesn't show the label on the page. I have added the control to the page correctly without any errors. I have event added the register tag in there.
html tag: <RandoIntegerControls:RandomIntegerControl ID="RandomIntegerControl1" runat="server"></RandoIntegerControls:RandomIntegerControl>
using System;
using System.Collections.Generic;

I have a heavy aspx page with lots of controls that are loaded from sql server. I use the cache were I can.On my aspx page I have an asp:Button that allows members to rebuild the page with the new content selected in each control.The page build or page_load takes about 15 sec (say). If users select the asp:button before the 15 sec page_load is completed. Some times I get performance issues with my controls. I don't get errors as I am using cache a lot etc.
QUESTION1: How can I stop a page_load event firing before the previous page_load process is completed, how do I stop impatient users getting carried away with too frequent page loads firing from the asp:button?Can I do some codebehind smarts that can nullify asp:button event while a previous page_load is process is still a work in progress.
Asp.net page_load function is loading twice.. hence it affects my page performance.
Does anyone know the reason it is loading twice.
No, iam not calling the page load function anywhere...
Let's say I have two pages on the same ASP.NET C# WebSite:
Page1.aspx does things in the Page_Load event
I navigate to Page2.aspx using the menu
Page2.aspx does some things then Response.Redirect back to Page1.aspx
Page1.aspx cannot do things in Page_Load event this time because it never fires.
I tried to turn off cache declaratively, tried using true for endResponse in my redirect... nothing seems to make a difference.
I am designing a page wherein I want to display just parts of a page on page_load (i.e. menu bar). Then a few seconds later, I would like to display the rest of the controls (i.e. charts). Is this possible? What I currently have is a page that displays the page skeleton and then on button_click(), the rest of the page is rendered. I want to fire a button_click() event on code-behind without actually requiring the user to click on the button but can't seem to find good tutorials/articles regarding this approach.
View 5 RepliesI have a web form with two RadioButtons, both use the same GroupName, both have AutoPostback enabled and both have an event handler for CheckChanged. I use tem to show/hide a Panel further down the form which is contained in an UpdatePanel with Conditional Update set and with both CheckedChanged events in the Triggers collection:
[Code]....
Now, the problem arises when I set the Checked property of either RadioButton in Page_Load, which results in the even not firing for the button which was marked as Checked (the event for the radio button whose property was not assigned does get fired). In fact, upon inspecting the source there was no 'onclick' attribute declared for the input element that was marked as checked in the Page_Load, whereas the other RadioButton did have the 'onclick' attribute properly set.
The layout of the form doesn't allow me to place the radio buttons within the UpdatePanel, so that is out of the question. Is the behavior explained above normal? am I missing anything? Both events fire once the assignment to the Checked property is removed from Page_Load.
this is my radio button list:

View 1 RepliesI have created a web application that docks other web applications into it.When an application is docked the app creates a link button in its "tool box" on the left hand side of the page, users can easily click on any link button to navigate to the desired docked app.
I have a web app that uses iframes to display other web applications inside it. In effect it is a docking application where users can easily access many web applications from within one main app, while staying within the main app. I am having challenges dynamically resizing the iframe based on the size of the application the user is accessing.I have searched the web and tried many ideas but have yet to discover the code that will do the trick.
First, for a docking web application is the iframe the best approach? I have see some posts on ajax but am uncertain how that will help.
Second, if an iframe is the way to do it does anyone have code that will completely liminate the need for iframe scroll bars?
Note:The applications docked in the main we app may be of any size and can change size as users interact with them.
Our website application needs to open other web sites Iframe.(Our application is web based tool to help high school children to analyze the websites. It has to show news websites to in one iframe and in rest of the page there will be questions related to the news website)
But since many websites use framekiller code, these sites take control of entire page. Is there any ternative way / solution to this problem?It is necessary to be able to open other sites in our website (in iframe or any alternate way), otherwise whole concept of our application will become void.
i open a iframe in a page, from that page opend in iframe, i want the page url.means one page mainpage.aspx have a iframe, that iframe open open a iframepage.aspx page.from the iframepage.aspx page's button click event i want to referesh the mainpage.aspx page.how can i do.
I'm sure I'm missing something extremely obvious here, but at this point I can't see it so I need the help.Anyway, I've got a repeater inside of an UpdatePanel. As of right now, I've stripped it down to this, just to try and isolate the problem:
[Code]....
Whether I add the handler during itemdatabound or I add the handler within the repeater itself, it doesn't seem to matter...the event itself doesn't fire. The AutoPostback itself seems to fire, but the event itself doesn't.
I'm running VS 2008 and .NET 3.5 SP1.
I want to implement hit tracking in an HttpModule in my ASP.NET app. Pretty simple, I thought. However, the BeginRequest event of my HttpModule is firing twice for each page hit. The site is very simple right now...no security, just a bit of database work. Should log one row per page hit. Why is this event firing twice?
Moreover, IHttpModule.BeginRequest actually fires a different number of times for the first page hit when running for the first time (from a closed web browser)...3 times when I'm hitting the DB to provide dynamic data for the page, and only 1 time for pages where the DB isn't hit. It fires 2 times for every page hit after the first one, regardless of whether or not I'm touching the DB.
It's interesting to note that Application_BeginRequest (in Global.asax) is always firing only once.
This is probably a really simple question, but I'm looking for a way of running a particular script on my website which will be ran every time a page is loaded. Basically it to work as if the script is in every .aspx Page_Load of my project.
I tried putting the script in the Application_Start event of the Global.asax file, however I noticed this didnt always run.
I need to do HTML code manipulation for every loaded page in my ASP.NET application. Where is the best place to put my method? Put code into every web page Page_Load event in not very smart, what other alternatives?
View 4 RepliesI have a class named PageBase inheriting from ASP.NET Page. I want to do something in PageBase's Page_Load.All pages in my application have their logic done on their Page_Load. I'm thinking of a way that Page_Load of both of PageBase and other pages run without having to override Page_Load in pages. Is it possbile?

I am having a problem with FireFox, I have an app using VS 2008 and it is using a Wizard control. Under IE the app only runs Page_Load once but FireFox is running it twice which would'nt be a big deal except the second time it is not going through as a post back so all of my setting are getting reset as if it was the first time through. I have see in previous post that the problem was autoEventWireup needed set to False, well mine is. I am using Ajax and UpdatePanel.

I'm developing an asp.net model -view-presenter (MVP), and to my surprise i see that when I click on the linkbutton in the window the Page_Load event is fired again. Is that normal? I'm used to webforms where we could just do a if (!Page.IsPostBack) if statement in the Page_Load. I did that but then no action happend when I clicked the linkbuttons in the window.
i have 1 master page with 5 pages that call it. now on the master page, I have few dropdowns and textboxes, and the calling pages only have a small article in the corner. I want to start a session on page_load event, so that if the user chooses to select a dropdown or put data in textbox, even if he clicks on the other 4 links of other pages, the data should stay.
