Is that a problem with my browser, or you skipped that one?

There's no variable named 'file', instead it should be 'uploads[i]' in place of 'file'.

pradeep - I know about the code error and the file is being updated. Thanks

I want to upload all files from a certain client-side folder. I do not want the user to have to data enter the file names as there could be many small files. Is there any way to do this via ASP.Net? In other words how do I populate the HttpContext.Current.Request.Files collection using client script?

I have asked several ASP.Net "gurus" abou this and they do not think it is possible due to browser security restrictions. Yet the upload control does it just fine.

Thanks

Awesome video .. You  rock...

One thing  i  wanted to know is that  ..can we develop the same with ASP.NET's  FileUpload  Control    instead of HTMLFile Control....

Waiting for your reply..

Thanks..

I did as pradeepkr and changed 'uploads[i]' in place of 'file'.

I do get some strange warning, in the end of the behind code:

catch(Exception Exp)

           {

               Span1.InnerHtml = "Upload(s) FAILED.";

           }

"The variable 'Exp' is declared but never used"

Anyone else tried it in VS2008 with c#?

However, if I just want to upload all files from a certain client-side folder, is there a video to show it?

1. You are trying to assign HttpPostedFile to a varible called file which dosen't even exist.

2. You are only changing the filename of the saved file and not the actual file itself. So you are only uploading one file multiple times.

3. You are using Visual Studio 2008 which is .NET 3.5 and the video is labeled as ASP.NET 2.

Therefore this video is useless.

I followed part 1 and 2, great job! :)

I'm trying to add a validation for the file type. I added this code on  btnSubmit_Click:

string FileExtention = System.IO.Path.GetExtension(upload.FileName);

if (FileExtention != ".jpg")

{

   lblMessage.Text = "only .jpg files";

   return;

}

I'm on the case when the user selects many files.

The thing is, when the user gets the message "only .jpg files", input controls are blank and the user has to select all the files all over again..

How do I keep the values on the input controls, so that the users corrects only the wrong selection(s)?

Thanks in advance.

Regards,

Sanaa RAMZI

I was wondering how to adjust the javascript to have a remove button next to the upload field to remove those created uploadfields if desired.

Thanks heaps,

Chris
