Question

HI

How to upload files asynchronously in asp.net without postback

thannking you.

Answer 1

You'll need to develop something which runs at client side (like Flash, Java, Silverlight) which breaks your files in chunks and send them directly to server in multiple requests.

Answer 2

You can use Flash (for example) for this task.

Answer 3

I have an open source control that does this in my site:

Answer 4

There is an AsyncFileUpload control in the Ajax control toolkit - AsyncFileUpload Sample. The toolkit is free and builds on top of the MS ASP.NET AJAX Extensions. If you are using VS 2008 and .NET 3.5 then you already have the extensions installed.

Answer 5

> There is an AsyncFileUpload control in the Ajax control toolkit - AsyncFileUpload Sample.

The control doesn't preserve query string on postback. So it's completely useless in current implementation.

Answer 6
