In source aspx page
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<cc1:AsyncFileUpload ID="AsyncFileUpload1"
runat="server" UploaderStyle="Modern" ThrobberID="img1" />
<br />
<asp:Button ID="btnUpload" runat="server" Text="Upload"
onclick="btnUpload_Click" />
in Aspx.cs
{

AsyncFileUpload1.SaveAs(Server.MapPath((AsyncFileUpload1.FileName)));
Label1.Text = "You uploaded " +
AsyncFileUpload1.FileName;
}


Try running this and you will find that the whole operation
happens asynchronously without a full page reload. Note
that, you would need to still put the AsyncFileUpload
control inside UpdatPanel for this behaviour. Otherwise, it
would behave like a regular postback control.
