Response.Redirect not working on an UpdatePanel if redirecting to a ClickOnce application (in some c

Posted By:      Posted Date: October 19, 2010    Points: 0   Category :ASP.Net


I have a strange issue. I am using the AjaxControlToolkit 3.0.30930 (the most recent). I have a very simple page with an UpdatePanel. A button on the UpdatePanel invokes Response.Redirect and passes the URL of a Click Once application on the same server. This works well if I run the website on my local system (Windows 7, IIS 7.5).

If I run the website on a remote system (Windows Server 2008, IIS 7.5, same settings) the redirect simply does not work when invoking the page from remote (using the IP address). Instead a postback is executed. Even if I use the IP address of the webserver to invoke the website locally on the webserver, the redirect does not work. Using http://localhost on the webserver the redirect works well.

I tried another test page with no UpdatePanel: The redirect works well in all scenarios.

I tried out to invoke the ClickOnce application using a link instead of Response.Redirect: The redirect works well in all scenarios, even with an UpdatePanel.

Does anyone have a clue what the problem might be?


Here is the ASPX:


<%@ Page Language="C#" AutoEventWireup="true" CodeFile="TestWithUpdatePanel.aspx.cs" Inherits="TestWithUpdatePanel" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//E

HttpContext.Current.Response.Redirect Not Working for Local Intranet Zone Sites


Hi All,

I have made this a seperate question as the original topic of another user who had a similiar issue was marked answered, however his answer is not mine.

In my infopath form, after the submit event, I am using HttpContext.Current.Response.Redirect(URL, false) to change the page.

I use an XPathNavigator to get the value for URL from a simple text box.

If i type in that text box http://www.google.com or http://www.hotmail.com, for instance, the page redirects perfectly.

However, if I type in a site address like http://intranet.mundaring.wa.gov.au or http://localhost for instance (which I need to), the form simply throws a critical error with no more detail than that.

The only pattern I can see is that the sites that DO work are in the Internet Zone, and all the sites that DO NOT work are all listed as Local Intranet sites.

I cannot change my local intranet sites as they are enforced by policy.

Please could somebody assist me with why this may be doing this. The form is opened from the intranet (a local site) so no zone change is taking place.

Response.Redirect slow


I'm in the middle of migrating servers and on the new server Response.Redirect is extremely slow. It takes around 20 seconds for the browser to get the redirect. This is something that was quick on the existing server. It's an ASP.NET 2.0 application, both servers are running IIS6.

Additionally, if I "manually" do the redirect, it's fast. For example:

Existing way:


takes around 20 seconds on the new server

New way:

Response.Status = "302 Moved Temporarily";
Response.AddHeader("Location", url);

is fast on the new server.

Any ideas why Response.Redirect would be so slow on the new server?

New off line application working with sdf file. Need advice


Hey Folks

I am working on a project currently where I need to get data out of a 3rd party vendor's software that uses a .sdf file I looked this up and its a SQL CE file. I was hoping to just link to with with access but thats apparently not going to happen. I need to link to the database extract data from it to a csv file for later use. I also and most important I need to get the data from it and create a report that can be printed while on a customers site that my or may not have web access so I need for this program to be on and off line. I had my webapplication that I have been working on open and was able to bring up the sdf file under the server exploere however I can't seem to get anything out of it when I try to do grid views or detail views errors out.

Can I use one of Visual Studio projects to create this sort of applicaiton if so what would be the best approach. I would love to get an access odbc driver since office is allready installed on the employee's laptop's

UpdateProgress with a dummy updatepanel not working


I have a Submit button and some functionality like updating DB and fetching next page in the button click event. This process takes a long time and I want to display a message saying "Progress...." right after clicking the botton. I want to do the same in 20 other pages. So, best way to do it wd be to put the modalpopup MPE or an Updateprogress in a usercontrol or in master page. I first tried putting both of these on the page itself to test and see and neither worked.

I tried using Update progress control with a dummy updatepanel and giving the Submit button as Asyntrigger to the dummy updatepanel. I have also tried using MPE but it didnt work either. Below is an example of what i did..

<asp:UpdatePanel ID="UpdatePanel1" runat=server><contenttemplate><triggers><asyntrigger ID= "Submit"> /> /> />

<asp:updateprogress ID="Progress1" unat=server AssociatedUpdatePanelID="UpdatePanel1"><Progresstemplate>Progress.... />/>

<asp:button ID= "Submit" runat=server >

I have nothing for updateprogress in code behind. Am i missing or doing somethign wrong here? Any help would be appreciated.



I need to open a new window with Response.Redirect, Is it possible?

Adding a cookie to a response.redirect vs. httpWebRequest


Hello, I will try to be as clear as I can be.  I'm sure this question has been asked but I can't find a suitable answer for this particular situation.

I need to be able to redirect the browser to a new 3rd party page while at the same time supplying a cookie required for some form of authentication on the 3rd party site.

I have managed to get this to work in the following manner:


'SessionID is predetermined by another HttpWebRequest/Response  

Dim sessionCookie As New Cookie("ezproxy", sessionID.Substring(1), "/", ".someother.site")

Dim CookieJar As New CookieContainer


rRequest = HttpWebRequest.Create("where I want to go")

rRequest.CookieContainer = CookieJar

rRequest.Method = "GET"


'Make the request and get the response.

rResponse = rRequest.GetResponse()


'Save cookie(s)

If (rResponse.Cookies.Count <> 0) Then

Exit Popup and response.redirect

Hi, I have a requirement to show an Exit Popup on one of our processing pages. I am showing the exit popup by registering a client side javascript like window.onbeforeunload = ShowExitPopUp(); The popup executes fine if you close the window, or try to type in a different URL. However the issue is that my processing page is also performing a "Response.Redirect" on the server side once the process completes. When response.redirect happens the exitpopup also shows up. Is there a way to have the exit popup not show up in that case? Since my server side code is running through an UpdatePanel, so I have tried registering the following, in an attempt to remove ExitPopup from client side. However this doesn't work since server side redirection happens before end request. Sys.WebForms.PageRequestManager.getInstance().add_endRequest(RemoveExitPopup); Has anyone faced a similar situation and handled it?
