My FileUpload Control Freeze

May 22, 2012

First off I'm using aspx pages with Visual Basic .net 2008 for the code behind.

I'm using a FileUpload control on an aspx web page to upload files to the server.

When I click on the Browse button I get a dialog box to select the file. I select the file and click the Open button and the entire file path populates the textbox portion of the control, just as it should.

However, when I use the same process to select a second file, after clicking the Open button it takes over 2 minutes for it to populate the textbox portion.

ASP.NET/.NET FileUpload Control?

Apr 28, 2011

I have a problem with FileUpload, when I select a file from the local machine, it will not bring the real path of the file, it will use the path for the project files and assume the file I am selecting is there, any ideas?

Example:File name is "Q.JPG" and is in "C:" when I browse to "C:" and select "Q.JPG" and click open, I get the following Error Could not find file 'C:Program FilesMicrosoft Visual Studio 8Common7IDEq.jpg'.So when I fire up the code for Uploading the file to FTP for example, it will return an error because file doesn't exist

.net - FileUpload ASP.NET Control Not Working Under Windows 7

Apr 28, 2010

I have a User Control that contains a System.Web.UI.WebControls.FileUpload control as well as a button to 'Submit'.

When the button is clicked code similar to the following is executed:

If FileUploadControl.HasFile Then
'Save the file and do some other stuff
End If

This code works just fine with Windows XP. However, if I run it from a Windows 7 64-bit machine using IE8 32-bit the HasFile property always returns false and nothing is saved?!

Asp.net - FileUpload Within A Wizard Control, Processed At The End

Oct 17, 2011

how to upload to FTP, however when using the FileUpload control inside a Wizard control, when you move to the next step, the File you selected gets cleared because of the postback. I need to be able to rename the file according to the results from the Wizard before uploading. So...

I finish my wizard It uploads some stuff to a database Renames the file according to those results Uploads the renamed file to the FTP server

I suspect I will need to follow a procedure something like this, having an upload button next to FileUpload

On "Upload" button click stream the file to the Web Server. Complete the Wizard. If the wizard completes successfully, rename file and stream to FTP server. If the wizard fails, what? Delete the file from the web server? How?

I think I understand the process, how to split my FTP Upload function into two parts with the proper error handling for when the wizard fails.

Protected Sub UploadFile(ByVal NewFilename As String)
Dim myFtpWebRequest As FtpWebRequest
Dim myFtpWebResponse As FtpWebResponse

Using A FileUpload Control In A Website Which Should Only Be Able To Upload Images?

Jun 18, 2012

I'm using a FileUpload control in a website which should only be able to upload images. To that end, I'm checking its MIME type before accepting the upload.Does anyone know whether the FileUpload.PostedFile.ContentType property comes from the file itself or the request? The latter is insecure, since the request can be spoofed. If that's the case, does anyone know a good way to validate a file securely?

Asp.net - FileUpload Control Inside Gridview (ajax Updatepanel)?

Mar 11, 2011

I've got a fileupload control inside of a gridview so that each row (item from the database) can have an attachment associated with it. I've got a button next to the fileupload control (besides the default browse... button to select the file) to actually take the file and upload it to a file server.This works great if I use this button "Upload". However, underneath my gridview I have another imagebutton that is outside of the gridview, its just sitting on the form / page.The idea of this "Update" button is when end users make changes to the grid I can simply loop through the grid and update the values they have entered to the database. This also works great.

Now here is my issue assume a user has 3 rows in the grid view. On 2 of these rows he decides to add an attachment but he never clicks the "Upload" button he only uses the standard browse button to select the file. Now instead of clicking the "Upload" button that is on the grid view he ends up clicking the "Update" button outside of the grid thinking that it will save his attachments.

So I decided to write code to grab the fileupload control from the grid using .FindControls("NameOfFileUploadControl") in my Update button loop where I loop through all the rows. Then I check if myFileUploadControl.HasFile property to see if there exists a file and if there does upload the file then continue with the code.

The issue is when I click this "Update" button .HasFile always returns false even though I can see the text string of the path in the fileuploadcontrol textbox (the standard one next to the browse button). Is it because this goes back to the page load event and checks if it is a post back? What causes this and how can I fix it?

edit:Im adding some code because im still confused with this

Protected Sub SaveGrid()
For Each Row As GridViewRow In Me.gvLineItems.Rows
Dim f As FileUpload = CType(Row.FindControl("fuAttachment"), FileUpload)

[code]....

This method gets called on a click of a button... The fileupload control is in an of a gridview that is wrapped inside of an UpdatePanel:

<asp:FileUpload Width="90px" Font-Size="xx-small" ID="fuAttachment" runat="server" />

So why is this property always returning false?

.net - ASP.NET Keep Fileupload After Postback?

Jul 13, 2010

I'm writing an intranet ASP.NET page using VB.NET. I've run into a particularly nasty problem dealing with handling file uploads. I'll do my best to explain the problem, and perhaps someone can help.

My problem is almost a duplicate of this one, or this one, except (other than the filename) I don't care about sending the file to the server until the other data has been reviewed. here's the situation:

Joe Q. Dataentry inputs some data into several fields. The first 3 are drop down, and when he changes the selection, a postback event is fired that queries a database for valid entries for the other drop down selections. After selecting the values, he inputs some other data, chooses a file to accompany the data and clicks the "Update" button. When he hits the button, it fires a postback event that sends the current data to the server to be validated. The data will create a change in the database, so he is presented with a view of the current state, and what it will look like when his changes are made. He can now either confirm or cancel the operation for whatever reason.

Part of the data he will see involves the extension of the file which may be a PDF, or could also be some image file or other document.

Now here's where my problem is - on each postback event, the fileupload dialog is cleared. I was getting around it by creating a temporary file on the first postback and then renaming if he clicks OK or deleting on Cancel... but I need to do a variety of things, based on the previous state of data and the filename. I've tried to keep some session variables to retain the filename, and that works OK for just renaming the file, but for what I need to do it gets unwieldy.

What I want to do is be able to have the postback event to present the changes, and then when the user clicks "OK", submit the file. Is there any possible way to do that?

One of my thoughts was to do some of the validation client-side (I'm already re-validating server side so I'm not too worried about data security there), but I don't know how I could get the information from the database query. It appears that what I want to do is prevent a certain button from firing a full postback. Is there any way to do that?I have an update panel on the page already - is there any way for the button to only post what's in the update panel?

FileUpload - How To Trap Maxfilesize

Aug 26, 2006

The fileupload control works well for files < 4MB (maxrequestlength), but if the file is larger than this the program fails with: - Server error in '/xxxxx' application Maximum request length exceededHow do I trap this so that I can return a better error message? The failure occurs before the Page Load from any callback, so I can't see any way of trapping the error, and I haven't seen any event or property of the Fileupload control that I can set to say "Do this when Max Request Length is exceeded"

Asp.net - Zero Size Files Uploaded With FTP FileUpload?

Oct 12, 2011

I've been reading gobs of articles on FTP upload in ASP.NET recently and they all seem to make sense, but every time I've tried implementing them I either get an empty file uploaded, or no file at all. Here are some of the articles I've been reading:Managing FTP Transfers from an ASP.NET Web Page By John Peterson FileUpload Control Doesn't Give Full Path...How to: Upload Files with the FileUpload Web Server Control I know exactly what the problem is but I don't know how to fix it. I can pass the file name from the FileUpload control, but the path does not exist for security concerns. However, the StreamReader object requires the fully qualified path of the file to be uploaded, so how the heck do I get that? I'm at my wits end!Let's use the example by John Peterson that I linked above. Here's the code:
