Asp.net - Firefox Response.redirect Not Working For Files?
Aug 12, 2011
I am trying to allow the user to download an excel file, by using
Response.Redirect(
"http://localhost/myapp/download_folder/example excel file_july.xls")
in page load of an ASP.net page but on the client side i a m getting the following screen in firefox 3.5 You can observe that the file name and file type are shown as empty fields. The ok and cancel buttons are not doing anything.This happens only in firefox 3.5, it is working in firefox later versions and other browsers.I tried clearing the Response with Response.Clear(), using Response.BinaryWrite with the file byte array and even tried to open the file with the javascript by calling window.open(url).

If you try to access a password protected page it does a security check and redirects you if you are not logged in, retaining the URL (ie. Members/MemberLogin.aspx?oc=/PodCast/Default.aspx)The vb script places the "/PodCast/Default.aspx" in a variable and holds it until the login process is complete.Once the user types in their username and password it is suppose to do a Response.Redirect(strRedirectURL) and go to the "/PodCast/Default.aspx" but instead it goes to the default.aspx page for logging in successfully

Does someone know If Response.Redirect can be used inside a method of a web service. I'm trying and I get an error. If I use it outside of the web service I have no problems.

My ASP.NET (VB.NET) application uses SiteMaps to display a navigation menu on the top of each page. In the code behind of some of the pages, I am dynamically amending the URLs of the SiteMaps nodes (to add parameters to the end of the URL) e.g. say I have somePage.aspx.vb and anotherPage.aspx.vb and they both contain the following:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
AddHandler SiteMap.SiteMapResolve, AddressOf Me.ExpandForumPaths
If Not Page.IsPostBack Then
Setup()
[code]....
My problem is this, if I am in the code behind of somePage.aspx and I do a Response.Redirect("~/anotherPage.aspx") - then, when anotherPage.aspx.vb is being loaded, it is the ExpandFormumPaths method of somePage.aspx.vb that is hit, not that of anotherPage.aspx.vb.
My understanding is that a Response.Redirect tells the browser to do a new request to the supplied URL - I don't know why it's hitting the method belonging to the previous page.
I've tried amending the method names (i.e. not having the node processing method called ExpandFormumPaths in all classes) but I still encountered the same issue.
When I go straight to the URL of anotherPage.aspx the correct method is hit, it is only when I am using Response.Redirect that this happens.

I'm fairly new to VB.net and this is my first post on this forum.I'm creating a website in Visual Web Developer 2010 Express in ASP.NET/VB and I'm trying to find out how to alternate a Reponse.Redirect, basically I'm looking to redirect every other visitor to go to a different site.
For example:
Visitor 1 gets: Response.Redirect("http://site-a.com")
Visitor 2 gets: Response.Redirect("http://site-b.com")
Visitor 3 gets: Response.Redirect("http://site-a.com")
Visitor 4 gets: Response.Redirect("http://site-b.com")
and so on
Also, if there is a way to set a cookie for that visitor, so if they visited within let's say the last 90 days, they will go to the same site they visited before, and not be redirected by the Response.Redirect.

My VB.net tabcontainer needs to stay on the active tab when I have each submit going through the response.redirect. How can I achieve this? I need that response.redirect there because it will show what has been added in the main tab container.
<asp:TabContainer runat="server" ActiveTabIndex="0" Height="200px"
Width="175px" ScrollBars="Auto" EnableTheming="True" Font-
Underline="False" ID="TabContainer2" EnableViewState="False"
Style="float:right; padding-left: 110px; margin-bottom: 340px;"
OnActiveTabChanged="TabContainer1_ActiveTabChanged">

I've got a strange problem with a Response.Redirect. I'm using VB.NET with the .NET 2 framework (so VS2005 & SP1).I've got a page that I do a form submit on (that's a proper form method="POST" hard-coded onto the page) and that properly posts me back the page data which is then processed. As part of that processing the system determines if we need to get sent to another URL after processing has been complete. So the request.httpmethod = "POST".
So if the "GotoPage" parameter has a URL specified we then do a response.redirect(URL, false). (False as we want page processing to complete in order to write some timing logs etc).The page correctly redirects but instead of the response having a "GET" as the request.httpmethod it has a "POST" instead Now, we're using our own custom framework so that we use the HTTPRequest method to determine if a page has been posted back or is being "Getted" so the "IsPagePostBack" property doesn't work (that only works when you're using the normal .NET controls and form submissions). In all other instances our code works happily but what might be causing the Request.httpMethod to not be being set correctly ? I've tried doing a response.clear before the redirect in case headers are being written out before hand but to no avail.

I've noticed that when I Response.Redirect to an .aspx page, it sometimes displays a cached page instead of actually executing the page and pulling fresh data from the database. I'm not using output caching or anything special in .Net here -- this is a CRM, and the caching is either happening on the client or, perhaps more likely, automatically in IIS. There is never a querystring involved, by the way. I'm passing a key via session. I know that if I used the querystring it would probably partially bypass the cache problem, but it's not an option in this case.
I did a little digging, and some people get around this by using Server.Transfer (which actually behaves differently than Response.Redirect and some of the details are not always desirable), and some other people said to set Response.Cache.SetCacheability(HttpCacheability.NoCache) on the page where I want to avoid caching. I thought .aspx pages were always flagged to avoid caching. Right?

I have a page in which one chooses from a selection of dynamically generated buttons. The ASPX code is as follows:
<div>
<asp:Repeater ID="rptrHalls" runat="server" OnItemCommand="Choose_Hall">
<ItemTemplate>
<asp:Button ID="btnChooseHall" runat="server"
[code]....
When I first tried running the code I received an error message of "Invalid postback/callback argument". I set the ASPX page to have a enableEventValidation="false" property and tried running it again. It generates the page fine but when I click on a dynamically generated button it acts as if it is loading something and then just brings me back to select_hall.aspx (the page all this code is one), when (as you can see above) it should take me to select_room.aspx.

I have a Web application (Help Desk Ticket System) with an inbox to monitor incoming requests and made some filter buttons that help the user arrange the requests based on requester name, creation date, etc.
Every filter will simply call the same page but will add some code to the query string. Example, if the user presses a button labeled [Sort by Date] here is the code behind for that button:
[Code]...
But I know that Response.Redirect does not accept javascript, and I don't want to split the code between Code Behind file, and ASPX file (adding OnClientClick attribute) because I will need to perform both VB instructions and also redirecting the user.

I am working on a VB.NET web application. When someone successfully changes their password I want to show a popup message that lets them know it was changed successfully. After they click OK I want to redirect them to the main page. Code looks like this:
ClientScript.RegisterStartupScript(Me.GetType(), "confirmScript", "ConfirmNewUser();", True)
Response.Redirect("MainPage.aspx")
Why does the redirect happen and the alert popup never displays?

in my asp.net application, two buttons call a javascript function called refreshView, below is the function refreshView.
function RefreshView() {
__doPostBack('ButtonApply', '')
window.parent.location.href = "dashboardtree.aspx"
}
In IE, this is working correctly, but in firefox and safari the page refreshes (due to the window.parent.location) - but never calls the doPostBack (i was able to tell this using tracepoint and the sub that is called stores values to the database, the values are not being stored as well, sub is never hit). Below is the first line of the sub.
Private Sub ButtonApply_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ButtonApply.Click
Can anyone see why this would not work? I figured I could always replace the doPostBack with pageMethods and create a new sub/function - but I'd like to complete this the way it currently is.

Lets say excel1 contains A as work sheet, excel2 contains B as work sheet ,excel3 contains C as work sheet ,excel4 contains D as work sheet ,excel5 contains E as work sheet .Now my output excel file should look like..OutputExcel with A, B, C, D, E along with respective data.But my current code is giving output as A,B,C worksheets along with respective data but its creating blank sheet1,sheet2 in place of D & E.

I have inherited a rather large project consisting of an application written in VB6 and several DLL's and ActiveX controls written in VB6, VB.NET 1.1 and VB.NET 2. I want to change one of the settings for one of the DLL's written in VB.NET 2 that is in its application.dll.config file, but it seems to be having no effect.My main VB6 application (I will call it Alpha) has a configuration file (Alpha.exe.cnfig) which contains settings used by my VB.NET 1.1 DLL (which I will call Bravo). After calling Bravo, Alpha calls Charlie (my VB.NET 2 DLL). However, even though I have changed the application settings in Charlie.dll.config in the subdirectory where the DLL lives, it has no effect. I have tried putting Charlie's settings in Alpha's config file but this causes Bravo to fail with an automation error (which I think is because the format of the config files changed from .NET 1.1 and .NET 2).[code]If I try putting the applicationSettings section under directly beneath the appSettings section (i.e. as another child element of the configuration element) in Alpha.exe.config then Bravo.dll fails.
