Is there any way to tell the FileUpload control to produce a clientside dialog
with a particular filespec filter on it.

For example I would like to restrict users to only uploading pdf files.

Thanks
 
if (FileUpload1.HasFile)
{
string filename = FileUpload1.FileName;
string extension = System.IO.Path.GetExtension(FileUpload1.FileName);
if (extension == ".pdf")
{
//your upload code...
}
}

Hello Juan,
if (FileUpload1.HasFile)
{
string filename = FileUpload1.FileName;
string extension = System.IO.Path.GetExtension(FileUpload1.FileName);
if (extension == ".pdf")
{
//your upload code...
}
}

Thanks Juan. I already have something like that on the server-side.

I was hoping however to present the user of my site with a slightly friendlier
interface by masking out everything other than pdfs in the dialog itself.

Looking around the net it doesn't seem like it's possible though.
 
Hi Rory,

As Patrice said, the accept attribute is not widely supported in current
browsers. You can refer to this article for some workarounds:
http://www.cs.tut.fi/~jkorpela/forms/file.html#filter

I have another suggestion for you, that is using Silverlight, which is a
cross-browser plug-in. We can filter the file in this way:
OpenFileDialog openFileDialog1 = new OpenFileDialog();
openFileDialog1.Filter = "Image
Files(*.BMP;*.JPG;*.GIF)|*.BMP;*.JPG;*.GIF|All files (*.*)|*.*";

I suggest you to wait for the release of Silverlight 2. In the mean time
you can learn Silverlight 2 Beta 2 first.
To get started with Silverlight:

Please feel free to let me know if you have further questions. You can also
ask questions in the Silverlight forum:
