Visual Studio (ASP.NET) complains:
Validation (XHTML 1.0 Transitional): Element 'frameset' is not supported
Reason why?

XHTML does not allow frames unless you specify the frameset DTD. Either change the DTD or use standard HTML.

Error still exists when code is:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Frameset//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-frameset.dtd">

<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
    <title>Customer Account Information</title>

    <script type="text/javascript">
        function requestCustomerInfo() {
            var sId = document.getElementById("txtCustomerId").value;
            top.frames["hiddenFrame"].location = "GetCustomerData.aspx?id=" + sId;
        }

        function displayCustomerInfo(sText) {
            var divCustomerInfo = document.getElementById("divCustomerInfo");
            divCustomerInfo.innerHTML = sText;
        }
    </script>

</head>
<body>
    <form id="form1" runat="server">

    <frameset rows="100%,0" frameborder="0">
    <frame name="displayFrame" src="display.htm" noresize="noresize" />
    <frame name="hiddenFrame" src="about:blank" noresize="noresize" />
    </frameset>

    <p>Enter customer ID number to retrieve information:</p>
    <p>Customer ID: <input type="text" id="txtCustomerId" value="" /></p>
    <p><input type="button" value="Get Customer Info" onclick="requestCustomerInfo()" id="Button1" /></p>

    <div id="divCustomerInfo"></div>

    </form>
</body>
</html>

Any further ideas? Many thanks.

This isn't a valid HTML page. You must have either a <body> or a <frameset> but not both.
