<!-- i can use Repeater for this single record -->
<asp:Repeater runat="server" ID="rpt" DataSourceID="sds">
    <ItemTemplate>
        <%#Eval("Name") %>
        <br />
        <div>
            <%#Eval("HTML") %>
        </div>
    <ItemTemplate>
</asp:Repeater>

<!--
    or i can write CodeBehind method that generates HTML string. something like
    public string DetailHTML()
    {
        string name = GetFieldValueFromDataSource_Name();
        string html = GetFieldValueFromDataSource_HTML();

        return string.Format("{0}<br/><div>{1}</div>", name, html);

    }

    string GetFieldValueFromDataSource_HTML(){
        
        //get data from "sds" dynamically
    }
-->
<%=DetailHTML() %>

<!--    
    or there is another way this should be done?
