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

Posted By:      Posted Date: October 07, 2010    Points: 0   Category :ASP.Net

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.


 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

response.redirect cannot be called in a callback call


And I really need to.. anyone can tell me the reason why? The problem is that in the callback I call some session variables and if the session has expired, instead of throwing an exception, I want to redirect the user to the login page. 


Any idea will be awesome!!



Very Basic Question - Error message running first page


Hi Everyone,

I am running Windows 7 and I have gone into Control Panel and activated all of the IIS Functions.

The web application I am running was downloaded from the net (and has worked on other machines previously).  Once I downloaded it, I moved it into C:/inetpub/wwwroot/code/main.asp

I am a bit of a novice at this!  But I am hoping someone can point me in the right direction!


I get the following error when I try and run the web application through IE:

"An error occurred on the server when processing the URL. Please contact the system administrator. If you are the system administrator please click here to find out more about this error."

(When i click the "click here" button it just goes to the IIS site).


Appreciate any help I can get!

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

Any ideas?  Thanks

Need help with a custom error page that shows the error message details


I know how to alter the web config to redirect to an errors page but what I need to do is have the actual offending error message print to that page. This is a special request for testing reasons, I realize the whole point of a custom error page is to provide a user friendly message when an error occurs but for testing we want to show the user the message so they can copy and paste it into a ticketing system we are using for beta testing feedback.

Should I use the global.asax instead? I am pretty new to vb.net and am not sure how to get the actual error message to display on my custom error page. Any guidance would be greatly appreciated.

WebBrowser control error message page handling




I have WebBrowser control on my winform. When I try navigate to some web-site I get standard IE error pages like:

  • "Navigation to the webpage was canceled"
  • "The address is not valid"
  • "Page couldn't be loaded"
  • etc.

I need to handle these errors and return custom error message to user. Is there any way to solve this issue?

I know about NavigateError event from the OLE DWebBrowserEvents2 interface. I implemented it. But when some navigation error occures I need stay at page from which user tried navigate (CanGoBack property returns false if it's first page).

Is it real? How?

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?

Handling 404 page not found with Error page

Inserting personal error message in ValidationSummary



I am creating a web form that requires a lot of validation. I use many of the validation control in asp.net already like RequiredFieldValidator and CompareValidator. 

My Problem: after my custom validation for the value entered return an error message, and I pressed enter key when the field is empty, my custom error message is overlapped by my ValidationSummary. 

Setting my custom error to visible = false on button click also does not seem to work as it requires for me to enter the value first.

This made me think, is there a way to insert my custom validation inside the ValidationSummary as an error message like for other validation control?

Thanks in advance

urlrouting - page not found error


I have a dynamic data site setup and running locally fine from vs 2008.

When i deploy to a remote windows 2003 server (IIS6), all the pages also work ok apart from one page/table.  I can access it's list page,  but the edit and insert pages throw 404 errors.

I'm thinking it's a url routing/hosting issue as i've copied back the database from the remote server and it all works fine on my local machine.

Is there anything i can do to debug this behaviour?
