I'm building dynamically a series of ImageButton controls, and I want to assign them a hyperlink for downloading files.So say you got a dropdownlist of 3 items 1,2 and 3, if you select 1 it creates one imagebutton and pointrs to fileA, if you select 2 it creates two imagebuttons and the first one points to fileA and the second one to fileB and so on...Everything is wrapped in an UpdatePanel to avoid postbacks.I have a problem binding the download link in the ImageButton.navigateurl, and then downloading it. I don't know how to do it...
protected void Button1_Click(object sender, EventArgs e)
{
Panel myPanel = (Panel)UpdatePanel1.FindControl("Panel1");

I am calling a file download action from javascript:
$elem.click(function() {
window.location.href = 'MyController/MyFileDownloadAction';
});
The controller returns a file:
[code]...
This action has a pretty high likelyhood of throwing an exception (or at least not being able to return the file).
Due to the nature of the application (which contains a lot of dynamic content), I can't really redirect to an error page in this situation. The current page needs to stay open somehow.
So I'm ideally looking for something like a javascript pop-up, but afaik this isn't going to be possible since I don't know any way to return a javacript instruction in a non-ajaxed controller call. If I display an error page I need to force it to open in a new window some how. Is there any possible solution to this problem?

View 1 RepliesI'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?

hat's the best way to allow a user to pull down an RDP file, but to do so using AJAX? In other words, I have a hyperlink and I need an RDP file to be downloaded by the user, but without a full page refresh.
I tried to make an AJAX call using the following example for RDP. It seems to work on Chrome and Firefox, but not on any version of IE.
String content = <RDP Content Here>
Response.Clear();
Response.AddHeader("Content-Disposition", "attachment; filename=HelloWorld.rdp");
Response.Cache.SetCacheability(System.Web.HttpCacheability.NoCache);
Response.ContentType = "Content-Type=application/x-rdp rdp;charset=ISO-8859-1";
Response.AddHeader("Content-Length", content.Length.ToString());.......

I have struggled with this for the last 2-3 days. I have a tab container control with a update panel surrounding it. On one of the tabs I have allowed the user to upload and download files to a SQL Server database. The upload works fine and the download works fine only when I remove the update panel.
I have tried to implement the solution that's provided at the following location...http://encosia.com/2007/02/23/ajax-file-downloads-and-iframes/I had to modify the code a little bit to fit my scenario but it looks like it would work. Is there another way to download files from a database within a update panel?
If there isn't another way to do this what could be wrong with my code...following the example on the encosia site...

The code never gets past the if statement with in this java script. Should I put a trigger on the update panel to force a post back. Any help will be appreciated, java script is not my strong point.

I am exporting a datatable to an excel sheet. When the ExportToExcel event is fire it pops up a "file download dialog" asking if I want to open or save. What I want to do is right after user clicks on open, or save I would like to show a modal popup saying "Do you want to finalize this download?".
Here is some code, it all works except it won't show modal popup after exporting to excel. Why won't mpeFinalizeDownload.Show() run unless I comment out the line above it?

View 1 RepliesI 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?
