Use Update Panel if you want to prevent post back

@Vishal: update panel does postbacks partially. But it doesn't postback the entire page, so the redirection looks not happened but it does.

Have you place script manager before the update panel?

See
AsyncFileUpload is an ASP.NET AJAX Control that allows you asynchronously upload files to server. The file uploading results can be checked both in the server and client sides.

VB

<ajaxToolkit:AsyncFileUpload OnClientUploadError="uploadError"
     OnClientUploadComplete="uploadComplete" runat="server"
     ID="AsyncFileUpload1" Width="400px" UploaderStyle="Modern"
     UploadingBackColor="#CCFFFF" ThrobberID="myThrobber"
/>
