Web Forms :: Know When A Web Page Is Loaded In An Iframe
Mar 1, 2010
I'm loading a web page into an iframe. As the web I'm trying to load have some heavy stuff it takes a while to load. As it's not my page I cannot change the HTML code neither the codebehind, so I want to put a progress bar while loading the web into the iframe and stop when it finishes loading. I'm doing it through javascript and I tried to trigger it in every load/unload event of the webs codebehind with bad results. Finally, I tried to trigger it in the body's onload event. It seemed to work, but the progress bar dissapears a couple seconds before the web is fully loaded into the iframe.
Its possible to know when the web has finished loading the iframe or when the web page which is loading in the iframe has finnished loading?

When user cliick on the control before page fully loaded it goes to error page.
Following is the trace.
Execution Error
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.

I have a webform named Default.aspx and in it an iFrame...
The iFrame will load one of a few different pages/forms/aspx... (for this example lets just say its test.aspx)
On test.aspx I have 2 buttons Button1 and Button2 If I have code in my test.aspx.vb for Button1 click of:
button2.text = "hello world"
it looks as if it reloads test.aspx inside the iFrame and sure enough Button2 states "hello world"
So now lets say on the Default.aspx I also have a button and its named Button5.
How would I go about updating the Button5.Text from with in the vb code of Button1 click/vb code located on Test.aspx
I have looked over some other post [URL] and the tell of using "PreviousPage" but that not seam to be what I need, I want to be able to state the page/form I want to effect a control on it...
I know how to do this in jut standard VB.net (not web) its like:
FromName.ControleName.Text = "Hello World" but then again in VB.net windows apps you dont have Iframse to deal with...

I put an iframe in one page. above the ifame I put a menu. When user clicks on menu, appropriate pages are loaded in frame, it works.
But also I need by default one page to be loaded in iframe.
[Code]....
but when the page is loaded initially it can't find - src="~/HTMLpages/Information.htm".
[Code]....
I tried to remove src="" in definition and put it in Page_load
[Code]....
no effect.

In order to use a third party API, I had to create a page that does not have form runat="server" in it. Because my app is using MasterPages and have a consistent look and feel throughout the application, though not too thrilled w/ the solution, I had to use iframe to embed this page into my app.It works fine but here's what I want to do. When the API call succeeds, I display a message and want to also place a hyperlink to send the user back to their home page. I think you see what I'm getting at by now. If I do this and the user clicks the link, it's all happening within the iframe.How do I send the user back to his home page and affect the whole page and not just the iframe page?

I 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 have a page which includes serveral gridviews, pulling out data from my datasources. At this stage, the parameters are set withing the page, however it will use a querystring at the end of the url. Once the page is loaded, i then have an Email function calling a HTML reader, which basically captures the content of the page and pushes to the body of the email and then emails it out.
The issue i am having is where to place this stagement. I have tried to insert the email function in the Page (load complete) event, but it still seems to send out over 20 emails, which to me, means that the page hasnt finished? loading and is constantly calling the email function.
At this stage, i need this page to load .. i cant think of any other way, i can get the data sent to an email without the interim medium; the page.

I am writting an application that displays 3 visable text boxes and 1 hidden text box and one hidden button.
My application sets focus to the hidden text box.
The input comes from a barcode scanning gun which gives the "enter" command after the scan is complete...this essentially clicks the hidden submit button which moves the text from the hidden text box to the currently active visable text box.
To start the application does some verification on what was scanned then gives the user feedback on what was scanned then enters it into SQL.
My problem comes with the last scan...the page does not actually post back to give the user the neccessary confirmation before commiting the info to SQL and resetting the form.
Is there a way to either do somethig after the page has been rendered or do an additional post back somehow before calling the commit and reset functions?

I have a data driven asp.net website with frames on the top, left, right and center screen. If a page generates an error on any of the frames, I want to redirect the whole site back to the Default.aspx. Currently, when a frame page errors in one of the frames, that frame gets the error pages. Site is URL.... Is this something that can be handled?

I want to initialize text box with specific dates and after page is loaded, user can change dates and refresh the data on page.
When I set default date on pageload event, user's changes get lost as soon as page is refreshed.
txtStartDate.Text = DateTime.Now.AddMonths(-2).ToString();
txtEndDate.Text = DateTime.Now.ToString();
In past, I have used onInit event for such initialization but I am unable to find it on web form.

I have some serious performance Issues with Windows controls loading first time on IE Browser then subsequent request's. When ever i open Browser first time , mywebsite takes 7 seconds to load, but on subsequent request without closing browser it loads with-in 2 seconds.I Knew IIS on first time it re-compiles the process and for subsequent request's it wont perform and it cahches .I'm looking for better options to improve performance, when ever first time reqest's comes to web server.
On IIS 7 Server,I was using both Dynamic and Static compression enabled.Also,On application pool ,I set "ShutDown Time(Limit)" and "Startup Time(Limit") to 90 (seconds).Here is web.config i disable below to improve performance issues.
<trace enabled="false" pageOutput="false" />
<compilation debug="false"/>
Here is the Server Configuration
Windows 2008 Server
IIS 7 64 bit
Upto Date patches.

Got a windows forms user control dll embedded in an asp page using the html form control object tag as it needs to run client side. The windows form control does something and then needs to redirect to a another aspx page passing a parameter obtained from a calculation in the windows form contro dll. Is the redirect possible from the windows form control (same session id needs to be used) since obviously you can't call response.redirect since its not part of the server side wep page.
