### Response.Redirect in C# for page to page parameter passing

Looking for examples of this, but can't find anything specific. I'm new to ASP.NET, and C# at the same time... so I'm struggling to get it right...  Thanks, Nick

### Response.Redirect cannot be called in a page callback error message.

Hi.  I'm using the Dundas Chart Controls in VS 2005.  These controls are built utilizing AJAX.  I have a basic page with a dundas chart control containing a funnel chart.  The funnel contains Quotes, Sales Orders and Invoices.  When the user clicks on the control, I want to determine whether they clicked on Quotes, Sales Orders or Invoices and transfer to the appropriate Details Page.  I've got the code working to determine which transaction type they clicked on; but, I get the "Response.Redirect cannot be called in a page callback." error when the page tries to redirect.  Note: I get a similar issue if I try server.transfer.

Suggestions?

Here's my code:

Dim hitTestResult As Dundas.Charting.WebControl.HitTestResult = Chart1.HitTest(e.X, e.Y)

If Not (hitTestResult Is Nothing) Then

Dim clicked As Dundas.Charting.WebControl.DataPoint = hitTestResult.Series.Points(hitTestResult.PointIndex)

Select Case hitTestResult.PointIndex
Case 0

### Download a file then either redirect or refresh the page (after response.end)??

Hi all,

I am using some code similar to the code below to open a word document on my ASP.net app.  Once the file has been downloaded and opened I then want to either redirect to another page or refresh the screen but nothing works after response.end and if i add it before response.end the browser never downloads the file?

Response.Clear();
Response.AddHeader("Content-Disposition", "attachment; filename=" + file.Name                  
Response.AddHeader("Content-Length", file.Length.ToString());
Response.ContentType = "application/octet-stream";
Response.WriteFile(file.FullName);
Response.End();

Any ideas?  Thanks

### 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:

Response.Redirect(url);

takes around 20 seconds on the new server

New way:

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

is fast on the new server.

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

### Redirect to a mobile page

Hi please can anyone help? I have a simple website with a home page called defaut.aspx, also I have a page with in this site called mobile.aspx. My question is, bearing in mind that I posses very little knowledge of VB, what code do I need to place in the default.aspx to detect what kind of device someone is using and redirect them to the mobile page (mobile.aspx)? This needs to be quite up-to-date preferably for blackberry and nokia devices?

Thanks

### Detecting PPC device on startup page to redirect?

I was wondering (since a search didn't find any posts) if there is a way for my startup page to detect what kind of device (PocketPC or web browser specifically) is loading the page and if it is a PocketPC, then redirect to the mobile pages? I will only be using PocketPC's exclusively as a mobile device.

Thanks for any suggestions!

### Response.Redirect

### 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")

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

rRequest.Method = "GET"

''''

'Make the request and get the response.

rResponse = rRequest.GetResponse()

''''

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

For Each cook

### 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?

### How to set the variation root redirect page to ALWAYS go to a preset label?

Hi. I have setup variations and I have 4 labels, SE EN FI DK. This is a public website and I want every visitor to first be directed to the predetermined label, for example SE. This no matter what setting they have in their browser... In Sweden, most people have English as the language in the browser since this gets you better content in most places, but in this case, it gets them the EN label instead of the SE label as default. How can I change this in the best way possible? Are there any easily adaptable solutions available? Like on codeplex? The MSDN way is not to my liking, manually customize every front end or compile my own DLL....Noo, there has to be a better way right? (How to: Customize the Variations Label Control Logic http://msdn.microsoft.com/en-us/library/ms551625.aspx) Appreciate any help you can give me on this.
