Download Button - File Downloading Cancels Other Operations

Apr 13, 2012

In my project, I've created a download button. This button shall perform 3tasks:

1. Change label text
2. Download file
3. Make the button invisible

The following code changes the label text and make the button invisible:

Code:

Protected Sub btnDownload_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnDownload.Click
lblDownload.Text = "<h3>Thank you for downloading </h3>"
btnDownload.Visible = False
End Sub

When I add a piece of code that handles the file download, the label text is not changed and button remains visible.
Here is the code:

Code:
Protected Sub btnDownload_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnDownload.Click
Dim URL As String = "~/myfile.exe"
Dim fileInfo As FileInfo = New FileInfo(Server.MapPath(URL))
If fileInfo.Exists Then
Response.Clear()

[Code] ....

File downloading cancels other operations.

Web Forms :: Check For Button Click Event In Form_Load()?

Jan 26, 2011

On my form I refresh a dataset in the Page_Load() event. But I also have a filter button which changes the dataset and reloads it. When the user clicks a button, the dataset gets refreshed twice. I would like to modify the Page_Load() event so that if the page is being reloaded because of a button click event, then I will skip refreshing the dataset in the Page_Load() event. Is it is possible to determine that the page is reloading due to a button click event?

Usercontrols - Button Click Not Caught (button In User Control Which Is Dynamically Loaded In Repeater)?

Jun 4, 2010

I have written a user control that captures some user input and has a Save button to save it to the DB. I use a repeater to render a number of these controls on the page - imagine a list of multiple choice questions with a Save button by each question.

I am loading the user control inside the repeater's ItemDataBound event like this (code simplified):

[code]....

The problem is that when the Save button is clicked, the page posts back, but lbnUpdate_Click is not called. The Page_Load event of the page itself is called however.

I should mention that the repeater is part of a user control, and that user control is loaded inside another user control (this is a DotNetNuke site which makes heavy use of user controls). The Save button link looks like this:

javascript:__doPostBack('dnn$ctr498$AssignmentsList$rptAssignments$ctl04$ctl00$lbnUpdate','')

Check What User Is Trying To Access A File?

Nov 29, 2010

i have an ASP.NET website which is using a filestream to read in a PDF image from a UNC share on a remote server 2003 box.

i attempt to load the file on the site (which simply embeds a PDF viewer on the site) but when i debug the code, it's throwing a security exception when i attempt to access the file. saying "access to ___ path is denied".

so... i granted access to the UNC path directory to the ASPNET user. i also granted access to the user that's specified for anonymous access in the site itself in IIS.
nothing.

however, i grant "everybody" access and the file comes through.

so, i need to know WHO is trying to access the file. the assumption is either the ASPNET user or the anonymous user setup in IIS. neither of which is gaining access. i tried to set up file auditing on the server2003 box but it's not logging a failure in the security event log when i get an access denied exception.

How To Create A Webpage That Allows The User To Click A Button

May 19, 2010

I'm trying to create a webpage that allows the user to click a button and it will open up a folder on their local hard drive. I've tried doing this in html and javascript, but from what I've read I don't think it is possible (reguardless I want to do it in asp.net so I can learn about it). However I was able to open up a folder when the page loads with asp.net using C#. My problem is that I cannot figure out how to get it to run when the user clicks a button or a link. How can I make the C# CodeBehind run when the user clicks a button?

Generating XML File On Button Click?

Jun 10, 2010

I have a client that is looking for a photogallery in flash, they already have one in mind they found. Since the site will be maintained by them, i was wondering if there is a way to generate an XML file via a button click so when they are logged into the admin console, they can update the XML with a simple click and it updates the gallery.

I will be giving them the ability to upload images to the site as well as deleting and updating existing images, so once they have done all that, they can click a button and that takes all the new updated images in the directory and generates a new XML file for the flash file to use.

Or is there another gallery i can use to give them the same look? This is the gallery they found and like: [URL]

Web Forms :: Downloading A File - File Name Is Shown Incorrectly On Opening

Apr 21, 2010

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 ?

We use this code to set the filename :

fileName = Server.UrlPathEncode(fileName);
Response.AppendHeader("Content-Disposition", "attachment; filename="" + fileName + """);
