I've a gridview which I am rendering to a html text writer and allowing clients to download as an excel spreadsheet using Response.Write. I'm using AJAX in my website now and suddenly it stopped working. This is the code I'm using
public static void Convert(DataSet ds, HttpResponse response) { try { //1. declare filename to export string filename = "export"; //2. clear response object response.Clear(); response.Charset = ""; //3. set response mime type to excel response.ContentType = "application/vnd.ms-excel"; //4. prompt user to download the file response.AppendHeader("content-disposition", "attachment; filename=" + filename + ".xls"); //5. create a string writer StringWriter stringWrite = new StringWriter(); //6. create html writer which uses the string writer HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite); //7. instantiate a gridview GridView gv = new GridView(); //8. set gridview datasource to the dataset gv.DataSource = ds.Tables[0]; //9. bind gridview gv.DataBind(); //10. tell the gridview to render itself into htmltextwriter gv.RenderControl(htmlWrite); //11. output html response.Write(stringWrite.ToString()); //12. end response response.End(); } catch (Exception ex) { string str = ex.Message; } }
I've found that Response.Write doesn't work with AJAX. Are there any alternatives to this?
I am using a custom event in third party library for my asp.net project. When the event happens, I need to redirect to another page. Problem is that since it is custom event, Server.Transfer or Response.Redirect can't be used (I tried but got "response is not available in this context"). So I think best way would be to trigger post back in the event and redirect in page_load event on appropriate conditions. Is this right approach or is there any better idea? And, how can I trigger postback?
I have just upgraded my web application from 3.5 to 4. There is one issue that I am now having that is easy to reproduce. I am hoping you can help me determine the best way to overcome this issue.I use Ajax and the AjaxControlToolKit. If you create a new aspx page and add an UpdatePanel and then add a button on the UpdatePanel. Then for button_click have it do Response.Redirect("SomeOtherPage.aspx") and it will give you a 404 error.Sample:
In Firefox (3.5 or 3.0), AJAX toolkit modal popups move just before a redirect.It's as if the positioning css is ignored. The rest of the css appears to be honoured i.e. the popup appearance doesn't change but it jumps to the top left-hand corner.
The test code below reproduces the issue. It only happens in Firefox. I am going to try to work around it by implementing client-side-popup-hiding measures but I would still like to know why it is happening.
I used a modelPopupExtender to make a screen freeze. after the saving i do an response.redirect to the same page but when i do that i could see the panel saving again before reload.
here is the code
[Code]....
on Code Behind when finished button clicked i do show the next view from the multiview as well as the New button. inside the finished button click event i do mpeScreenFreez.Hide(); to hide the popupExtender. When i response.redirect i could see the panFreeze panel poping up just before relaod.
I'm using ASP.Net 2008 and C# and Ajax. I have wired up my ajax updatepanel to update the buttons within them in the gridview control's RowCommand event. However, at the end of this event, I call the Response.Redirect(commandArgs[2]); to open either Word or Adobe docs that user selected. And this line of code stops my Ajax updatepnael to update my 2 buttons' enabled properties. I thought maybe there is another way to open docs that won't interfer with my Ajax updatepanel and what will that be?
Observing this strange behaviour in Firefox when a history point is added using ScriptManager. Firefox retains the history point in a URL even if Redirect the browser to a new URL.teps to recreate:1. Save the code below as an aspx page in a website and browse to it.2. Click on the "AddHistoryPoint" button. It just adds a history point to the browser URL. (#&&key1=value1 gets added to URL)3. Now click on "Redirect to Google" button. The browser redirects to [URL]) is retained in the URL bar.This happens only in FF (checked in v3.5 and v3.6) browser. This odd behaviour in FF causes lot ot trouble when redirecting to other pages in the same site that change their state based on the state info present in URL.
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.

Even if setting EnablePartialRendering to false, the redirect works. This is a big clue, that the UpdatePanel causes the problem.
I want to redirect to "~/City/Göteborg", but if I just write Response.Redirect("~/City/Göteborg"); I will end up with an ugly URL in the address-bar like this: http://www.mysite.com/City/G%c3%b6teborg..
So my question is how to redirect to obtain a clean url like http://www.mysite.com/City/Göteborg?

Is it necessary to call Response.End() after Response.Redirect(url) Update for all the answers. Because some answers say that it's necessary and others say no, I have searched more and have found in msdn under remarks the following: Redirect calls End which raises a ThreadAbortException exception upon completion.
I have an ASP.NET app that has a class that writes to the event log. Now it has been working fine when called from a WF Work Flow , as the WF runs under the app pool account (Network Service).
Now I want to use this event log class in an aspx page, which is where I am running into trouble becuase the aspx page is running under the IUSR account and I get an Access is Denied error, stating "Cannot open log for source 'XXX'. You may not have write access.".
Now my question is, how can I give the IUSR account permission to write to the event log, or is there another, better (not overly complicated), way?
I am working on a website that I inherited (ASP.NET and C#), and I noticed that in almost EVERY method in the code behind of the project pages (except some helper methods), the original author uses Response.Redirect() to redirect to a page (typically home.aspx, but not always).
What is the purpose of doing this? It seems unneeded to me - at least it doesn't appear to change anything the website is doing if I keep it in or remove it.
I have a flash image slider with a button below each image. When i press that button, the user is redirected to a new page where i add that image product to my cart. The problem is that after doing the adding, i want to redirect the user back to the initial page.
note that in Firefox is working fine but in IE or Chrome it is DOWNLOADING the swf...If i comment Response.Redict(...) the user remains on this page so the click button is working well, only the redirect seems to be the problem.
Edit: The problem seems to be that Request.UrlReferrer keeps as link not the initial page containing the swf but the swf itself.
So, instead of doing redirect to:[URL] if does redirect to the swf contained on the Index.aspx page[URL]
Solved: with a session variable where i keep the initial page's url
