As far as I can understand SUtNumber is a sub-class of NumberField, isn't that so? If so, you can use Items.
Example
<%@ Page Language="C#" %>
<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<head runat="server">
<title>Ext.Net Example</title>
<script type="text/javascript">
var isContent = function (c) {
return c.items && c.items.getCount() === 0;
}
</script>
</head>
<body>
<form runat="server">
<ext:ResourceManager runat="server" />
<ext:Panel ID="Panel1" runat="server" Title="Items">
<Items>
<ext:TextField runat="server" Text="I'm form Items" />
</Items>
</ext:Panel>
<ext:Panel ID="Panel2" runat="server" Title="Content">
