Web Forms :: Unable To Execute Code After Downloading File To A Browser
Jul 30, 2010
I have a web app which displays some data in a GridView. This GridView is populated with a method called BindGrid. The user selectes one or more rows from the grid, then clicks the Process button. What needs to happen is that the selected rows are assembled into a CSV file which is downloaded to the browser, then the database is updated to reflect which rows were selected, and the grid is refreshed so the previously selected rows are no longer displayed. This all sort of works, except...
My code is below, which is very similar to lots of snippets found in this forum.
The problem is that if I uncomment Response.End(), or replace it with ApplicationInstance.CompleteRequest, it all works great except none of the code after Response.End() executes, and so the log entry is not made and the grid is not refreshed.
If I comment Response.End(), as in the snippet below, the code following does run, including the log entry and the call to BindGrid. (I know that because log entries inside BindGrid are made.) However, the page does not refresh. If I press F5 to refresh the page, it redraws correctly refreshed.
So the question is, how do I refresh the page after downloading the file?
I have tried calling both Response.Redirect and Server.Transfer after BindGrid
I'm missing a the code browser when I create pages that have the code not placed in a seperate file. For pages with .asp.vb files I get the browser correctly.
I think it's called a code browser but just in case it's not I mean the dropdown that shows Page Events, Buttons and other controls that can be selected along with their events.
How do I turn on those dropdowns for pages with code behind that uses <script> tags in the actual .aspx page?
Included (Showing page events just under the tab):
i have an aspx page that loads and displays a text file in a broswer window and it used to work, I made no changes to it and now testing shows additional content appended below the file.
Here is the text file:
testing...
Here is what is displayed:
[Code]....
The additional output looks like the aspx page itself, which has only a close button incase the file load fails.
I'm trying to understand how to execute AJAX animation on an asp button that has to execute code on Postback. In other words, I have button with code behind that needs to be excuted, but at the same time want to be able to have one of animation extenders be applied to it. I understand that I need to use the BeginRequest Event, I'm just not sure how, or which javascript commands to use to call the ajax animation so the postback will still occur.
I have made an application where I am displaying the .pdf , .doc , .docx files. These files are uploading from an Admin Panel.When user place a mouse pointer on download icon provided in front of every file, it shows the complete path where it’s get saved.I want to avoid this path visibility even when user place mouse on download icon and even if it Inspect an element (as most modern browser will have this functionality).
we are working on a file download page. We want to download a file with a name with spaces and accents. Although the filename is shown correctly on the filedownload dialog, when we click open, the file name is shown with %e1%ba%a3n%20... on notepad. ('Save as' shows the correct name) This problem only happens in Internet Explorer.
Is there anyway we can Display the file name correctly (on the target application) after opening it (without saving) from file download dialog ?
downloading multiple files from the server side through the browser (i.e. Chrome) I've debbuged it the foreach iterates fine but it only downloads the first file.
Here's the code snippet:
FileInfo fInfo; SQLConnection = new SqlConnection(SQLConnectionString); foreach (CartItem CartProduct in Cart.Instance.Items) { [code].....
I've tried a couple of free ASP hosts (X10hosting and Heliohost) but I get the same problem when uploading an asp site - the asp file just shows the code in the browser. The site is sound because I've seen it in operation on other hosting.
I am using asp.net 2005, and my deployement server is Windows Server 2003.
I am invoking a .bat (which executes some cmd) file from my asp.net page.
But the cmd prompt not getting invoked . the application is waiting for long time in Process.Start() and after some time i am getting asp.net time out error.

b. i have checked with giving impersonation = true - It doesnt worked
c. I have checked with gsetting identity as 'Local System' , 'Local Server'in th eApplication pool of the IIS.
i am making a gridview in which textfield of password should match with the password stored in the database (table) .As soon as that happens, the file should be ready to download . now the problem is that the code is niether working nor showing any error, which is very sarcastic.
if (txtval.Text != null || txtval.Text !="") { if (txtval.Text == ds.Tables[0].Rows[0]["FilePassword"].ToString()) { lblmessage.Text = "File has been downloaded successfully."; WebClient fileReader = new WebClient();..........
In an ASP.NET web application using C#, when we double click on design it will go to code behind page (cs file), but problem here is, when we double click on design its going to script of source file. Why it is happening?
I have 4 checkboxes named(Laptop, Car, Phone, TV) and a button. when user checks one Car checkbox and clicks a button, car specifications pdf should be downloaded. Similarly when phone or laptop checkbox checked, relevant pdf's should be downloaded. For this i have written following code
[Code]....
This code is working well in VS2008 but has issues when run in localhost.
Issue --> Check one checkbox like chkPhone and click on button, the Phone pdf gets downloaded and uncheck chkPhone checkbox and check other one like chkCar and when clicked on button to download, getting following errors.
1. xml parsing error not well-formed --> this error is getting only in mozilla.
2. HTTP/1.1 100 Continue Server: Microsoft-IIS/5.1 Date: Wed, 09 Mar 2011 05:34:23 GMT X-Powered-By: ASP.NET HTTP/1.1 200 OK Server: Microsoft-IIS/5.1 Date: Wed, 09 Mar 2011 05:34:23 GMT X-Powered-By: ASP.NET X-AspNet-Version: 2.0.50727 Content-disposition: attachment; filename=Car.pdf;
I have googled the issues and find the following sites[URL] For second issue i added the following line
Works great on localhost. But when I upload it to the server with IIS6.it works 25% of the time. the other times, I just get an empty (0 bytes) file to download.
Ive created a Web App where it is possible to download an xml file from the server to the client. It works just fine except that the Save Dialog recognizes the file being dowloaded as of type .aspx and the name of the file as being the name of the page I' on. The page is called Download.aspx and it contains a button that when clicked executes the following code:
[Code]....
The save dialog appears and says:
Name: Download.aspx
Type: ASP.NET Server Page, 1,16KB
From: 127.0.0.1
If I download the file and open it it contains the correct Xml file content and nothing else, so it is working correctly. It just annoys me that it appears to the user that he is downloading the aspx site (and it shows up as such in windows explorer as well) rather than the xml file which is the actual content.
I have a page that has a note to the user about the file they're about to download and a button to click to start the download. When they click the button, it does a Response.Redirect to another page with the following code in its Page_Load:
I want the download to start and then I want this page (which is a tab in the browser) to close.
The code to download the file works fine. I just can't figure out how to close this tab when it's finished. I've read a lot of forum posts from people who are using similar code, but none of the suggestions seem to work for me. I understand that Response.End means that I can't put any more code this page; it will be ignored. But how do I get this tab to close?
I am developing a web application in which I am suddenly facing an issue. I have a webpage which contains many controls, one of the control is JQuery color picker. Now, I am upgrading my system with telerik controls. As part of this process, I replaced textbox(txtcolor) with radcolorpicker with a different id(colorPicker). Suddenly, my code behind file is not throwing any errors like 'unable to find txtColor'. It is running successfully without build errors. But, when I open the page, system is throwing runtime exception(txtColor not found) which is correct.
I tried to change other controls with asp.net controls, still the problem persists. So, I dont think it is anything to do with telerik.
