Iframe - Changing The PostBackUrl After A File Download?
Aug 26, 2010
I have a ASP.net which allows users to select a number of inputs and dropdown lists to filter the report and to download an Excel report after pressing a button on that same form.
The page can be used mulitple times, by changing the inputs and pressing the download button each time.
The button should be posting back to the hidden IFRAME to a separate webpage, but I am unable to change the target for the form on the fly as needed.
Additonally, when I download the file when pressing the "DownloadToExcel" button, the file downlodads as expected. However, any additional postbacks including updating the screen are posting back to report.aspx and not filter.aspx.
How do I correct the postback so it only postbacks once to download the file, and then change it back to the original page so the screen can continue to be used to filter and download a second report.
This may also eliminate the need of the IFRAME as well.
I'm about to submit my pad file to multiple sharware sites but the pad file has to have a direct link to the download file and can't link to a download page which is what I would like to do, so I can track the traffic and get the downloader's email before allowing the download. I am running an ASP.NET site in VB. Is there a way to tell the web app to redirect to a specific aspx page when it receives a request for a specific file?
i m creating asp.net Mobile website page to download symbian .sis file to mobile ,but its not geting download properly.its working perfectly on desktop.
I am downloading file from database using the following code. This code downloads an excel file from the database which has a macro attached to it when it is opened. This macro reads file name of the excel file and uses it for its computation. Everthing works file if user saves the file on his harddisk and then open if but if he directly opens the file from the dialog(by hitting 'Open' button) then file name of the opened excel file comes out be the name of the webform that has the above code and this leads to error in the macro. Is there any option through which i can control the name of the file if user directly opens the file from dialog or the option to disable or remove 'Open' button form the dialog?
In our application, we allow user to upload documents which can be PDF, Doc, XLS, TXT. Uploaded documents will be saved on web server. We need to display link for each document user uploaded and when user click on that link, it should open relevant document. it is expected to have required software to open relevant documents.
To upload document, we use saveAs method of FileUpload control and it works absolutely fine.Now, how to view it?I believe, i need to copy/download file to local user machine and need to open it using Process.Start.For that i need to find user local temp directory. if i put path.GetTempPath(), it gives me web server directory and copy file there.
This block of code display Download file Dialog for Open or Save the attached file.It's working fine in Mozila Firefox and IE8 but doesn't display Download file Dialog box in IE 7
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).
I have a simple 'file download' generic handler which sets the response contenttype and headers before sending the file through the same response.
I also have Response.Cache.SetCacheability(HttpCacheability.server) set in the global.asax.
As I have noticed from various sources, Internet Explorer doesn't like this no-cache setting and gives an error when trying to download the file (requested site unavailable or cannot be found).
I thought maybe I could override this setting in the .ashx page, so I alter the response's cacheability setting to public. This did not solve the issue. removing the line from global.asax does solve the problem but obviously affects the whole site.
Is there a way of setting the cachability just for my generic handler?
In an ASP.NET WebForms 2.0 site we are encountering an intermittent bug in IE6 whereby a file download attempt results in the contents of the being shown directly in the browser as text, rather than the file save dialog being displayed. Our application allows the user to download both PDF and CSV files. The code we're using is:
This is called from the code-behind click event handler of a button server control. Where are we going wrong with this approach? Edit Following James' answer to this posting, the code I'm using now looks like this:
HttpResponse response = HttpContext.Current.Response; response.ClearHeaders(); // Setting cache to NoCache was recommended, but doing so results in a security // warning in IE6 //response.Cache.SetCacheability(HttpCacheability.NoCache); response.AppendHeader("Content-Disposition", "attachment; filename="theFilename.pdf""); response.ContentType = "application/pdf"; response.BinaryWrite(MethodThatReturnsFileContents()); response.Flush(); response.End();
However, I don't believe that any of the changes made will fix the issue.
I'm trying to force a large (200+ MB) file to download that's on a remote server. The problem is that I can't use the "WriteFile()" function, since I'm not using a virtual path. Then, when I try:

I had a download task in my project, which inserts files and downloads these files. I did my table in database and have a column which has the path of file and folder in project which will have the files. I did this well and my files insert well in folder and path in database. But I could not download these files from folder with the ID of path from database
I calculate the total size of my PDF file which is mentioned below. What does this return? When I download a 2KB file, it returns a size of 2KB, which is correct. But when I download 2 files each of size 2KB, then the total size it returns is 2.16KB. Is that correct? Should it return 4KB?

i want to access a javascript function which resides in a script file from another page with iframe. my sample code :
Page from which javascript need to be accessed.
<iframe id="FRAMESET" src="default.htm" width="0%" height="0%"> <p> Your browser does not support iframes. </p> </iframe> default.htm <html xmlns="http://www.w3.org/1999/xhtml"> <head> <link href="Scripts/main.js" type="text/javascript" /> </head> <body> </body> </html> main.js function helloWorld() { alert("hello World"); }

I have created a web application that docks other web applications into it.When an application is docked the app creates a link button in its "tool box" on the left hand side of the page, users can easily click on any link button to navigate to the desired docked app.
I have a web app that uses iframes to display other web applications inside it. In effect it is a docking application where users can easily access many web applications from within one main app, while staying within the main app. I am having challenges dynamically resizing the iframe based on the size of the application the user is accessing.I have searched the web and tried many ideas but have yet to discover the code that will do the trick.
First, for a docking web application is the iframe the best approach? I have see some posts on ajax but am uncertain how that will help.
Second, if an iframe is the way to do it does anyone have code that will completely liminate the need for iframe scroll bars?
Note:The applications docked in the main we app may be of any size and can change size as users interact with them.
