I have a page that utilizes an IFrame to display another page within the first one. I am using ASP.NET 3.5 and when I click on a button to do a post back event, it causes Internet Explorer 7 to throw an error.

I have a page with two data bound list box controls on it. When I there is data in the controls the page crashes and i get "Internet Explorer cannot display the webpage". I have tried to set break points to see what is going on. I have tries to fill the boxes in the code behind instead of using a data source in the page. I have tried setting the page time out to 3 minutes. Nothing is working and I'm not sure what the problem is. The page works fine as long as there is no data in the controls. I'm trying to figure out what I am missing.

Listbox causes page to Crash getting "Internet Explorer cannot display the webpage" Instead of posting your entire code for us to review, could you post the specific portion of the code that you think is causing the problem (probably the retrieval or setting of the data).
I am developing an ASP.NET 4.0 web application in which I am trying to use an iframe to load a third party website:
<iframe id="ifr1" src="http://newdomain.com?id=test&password=123"
width="100%" height="600px">
</iframe>
The newdomain.com is trying to place cookies in the browser and IE dosent like that. I have no control over the application hosted on the newdomain.com. I have read a lot of articles which talk about having a P3P information added to the header of the page which hosts the iframe. So in my application's Global.asax I have the following code:
protected void Application_BeginRequest(object sender, EventArgs e)
{
HttpContext.Current.Response.AddHeader("p3p", "CP="IDC DSP COR ADM DEVi TAIi PSA PSD IVAi IVDi CONi HIS OUR IND CNT"");
}
But this doesn't work and I am really confused now.
I have seen multiple posts and websites regarding this issue, yet none of the solutions / workarounds posted have worked for me. I am trying to load an ASP.NET report into an iFrame. The iFrame will load correctly (across all browsers), but when I run the report, Internet Explorer only will show the following error:
ASP.NET session has expired I have tried to use an HTML form to POST and target the iframe, as the workaround suggests here: [URL]I have also tried adding the following to the web.config file of the report application:
<sessionState
mode="InProc"
stateConnectionString="tcpip=127.0.0.1:42424"
sqlConnectionString="data source=127.0.0.1;Trusted_Connection=yes"
cookieless="false"
timeout="20"
/>
I have also tried to set my server to use InProc mode, and that still does nothing.
I have a few years experience developing C#, I have been asked to learn ASP.NET for a web development project. Does anyone know of any crash course tutorials to enable me to achieve this quickly, either internet or literature based?

View 3 Replies i want to close internet explorer on if a button is closed which i can do with this code
Page.ClientScript.RegisterClientScriptBlock(Me.GetType, "jcrCallerID", "window.close();", True)
this code is working fine for me but it is also coming up with warning which i dont want.
The warning is saying the webpage is trying to close do you want to continue closing the webpage yes /no
I want to avoide this warning and just close the browser windows.
isn't there any way except setting the website as an application in IIS??because i want to create it in filesystem.thare are lots of links andi i almost all of them but i'm confused and it doesn't work.
View 2 RepliesI have asp button control on my page. Upon running in IE, it is not doing anything even postback. While the same is running perfect in Firefox. I have surfed the web regarding the problems and almost applied all the things. I have no double forms tag. I found one solution to set UseSubmitBehavior="false". After this, it work but my text box controls lose its content. I am using framework 3.5.
