infragistics 的 WebUpload 控件不会用，谁能帮帮我？
官方网站的示例我拷贝过来编译也不通过
<asp:Content ID="Content1" ContentPlaceHolderID="HeadContent" runat="Server">
<ig:HtmlLink ID="HtmlLink1" runat="server" type="text/css" rel="Stylesheet" href="/SamplesBrowser/SamplesCommon/aspnet/Common/Styles/jquery/css/themes/infragistics/infragistics.theme.css" />
<ig:HtmlLink ID="HtmlLink2" runat="server" type="text/css" rel="Stylesheet" href="/SamplesBrowser/SamplesCommon/aspnet/Common/Styles/jquery/css/structure/infragistics.css" />
<ig:HtmlScript ID="HtmlScript3" runat="server" Type="text/javascript" Src="/SamplesBrowser/SamplesCommon/aspnet/Common/Scripts/jquery/js/infragistics.js" />
<script type="text/javascript" language="javascript">
function onErrorHandler(e, args) {
$("#error-message").html(args.errorMessage).stop(true, true).fadeIn(500).delay(3000).fadeOut(500);
}
</script>
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="Server">
<igjq:WebUpload ID="webUpload1" runat="server"
Mode="Multiple" MaxSimultaneousFilesUploads="2"
OnUploadFinishing="webUpload1_OnUploadFinishing">
<ClientEvents OnError="onErrorHandler" />
</igjq:WebUpload>
<div id="error-message" style="color: #FF0000; font-weight: bold;"></div>
