Javascript - Response.Redirect AFTER Call To JS Alert Or Confirm?

Apr 13, 2011

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?

.net - Different Behaviour When Using Response.Redirect And SiteMaps?

Oct 7, 2011

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.

Alternate Or Toggle Response.Redirect?

Oct 7, 2011

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.

Asp.net - Response.Redirect, Keep Tabcontainer On Active Tab?

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.

.net - Response.redirect Sending Incorrect HTTPMethod?

Sep 22, 2009

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.

.NET Response.Redirect Not Working Properly On New Server?

Jun 3, 2010

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

C# - Why Does Response.Redirect Sometimes Pull Page From Cache

Jan 18, 2010

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?

.net - Response.Redirect Does Nothing (ASP.NET) And EventValidation Returns Error If Enabled?

Mar 7, 2011

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.

Direct Instruction For RESPONSE.REDIRECT To Go To Previous Page?

Jun 20, 2011

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.

Javascript - Redirect To Another Page Is Causing Dup Entries?

Oct 26, 2011

How to I redirect to another page *after* printing document? Things seemed to be working fine until this morning we discussed that users were submitting duplicate entries.The reason for this is that once the user clicks to Submit their request,they are presented with a button that says, ">>>Click Here To Print Form<<<<".

Users are required to print this form but for some reason, they forget to do so.In the event that they forget to print this form, they are taking back to the input screen with boxes still retaining the data they initially entered.Is there a way to redirec them to results.aspx page, whether they print the form or not?

function doPrint() {

Javascript - Writing Back A Function Through Response.Write()?

Apr 12, 2012

I am trying to return a javascript function using response.write in an aspx page. The problem is that the function i am returning has lots of quotes and they are conflicting with the repsonse.write syntax. Here is a sample code:

Response.Write(" If hello.StartsWith("H", StringComparison.InvariantCultureIgnoreCase) OrElse hello.StartsWith("W", System.StringComparison.InvariantCultureIgnoreCase) Then")

This is giving me a problem as the quotes inside are cutting off the response early. Is there a better way to do this?
