    Try this one:

    <%@ Page Language="C#" %>

<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>
<script runat="server">
    protected void FileUploadField_FileSelected(object sender, DirectEventArgs e) {
        if (this.FileUploadField1.HasFile)
        {
            HttpPostedFile file = FileUploadField1.PostedFile;
            file.SaveAs(@"d:\" + file.FileName);
        } 
    }
</script>
