No. AFAIK, it's not possible to do that with File Upload control. maybe. you may look around flash or ActiveX control.. I'm sure that HTML file control doesn't have that feature. So, you will have to check the extension at code-behind.

Specifying filter is not possible in file upload control. But you can check the file extension like this and alert user regarding that

if (File1.PostedFile.FileName.EndsWith(".exe"))
{
//Display message
}
else
//Upload

Use javascript for the validations since u cant filter the HtmlInputFile control. Ask if u want the code. u have 2 do it in the onchange method.

javascript cannot interact with the input control, or the file system, AFAIK.

you should use this code: private bool IsAccept(string fileName) { bool ok = false; string ext = System.IO.Path.GetExtension(fileName); if (ext == ".jpe" || ext == ".jpeg" || ext == ".pjpeg" || ext == ".gif" || ext == ".jpg" || ext == ".bmp" || ext == ".png" || ext == ".x-png") { ok = true; } return ok; } Hope that help you! vtkiet05

I guess the code vtkiet05 shows us is Server-side code. not Javascript. I believe that that code is not interacting with File System. It's just trying to get the extension of file by using System.IO.
