Not anything you want to do each time a transformation is displayed. Meaning if you're retieving 100 items in a repeater, that code will execute 100 times.

Maybe you want to display the parent page name and not get the template information from the page? If so you can use a macro in your text/html transformation like so:

{%CurrentDocument.Parent.DocumentName|(identity)GlobalAdministrator%}

Since transformation is essentially a user control you can do something like this:

<%@ Import Namespace="CMS.DocumentEngine" %>
<%@ Import Namespace="CMS.PortalEngine" %>
<%@ Import Namespace="CMS.Helpers" %>
<script runat="server">
string templateName = "";

protected void Page_Load(object sender, EventArgs e)
{
    if (CurrentDocument == null) return;
    // calculate it only once per request
    if(!RequestStockHelper.Contains("templateName"))
    {
        var parent = CurrentDocument.Parent;
        var templateID = (parent.NodeTemplateID == 0)? parent.DocumentPageTemplateID : parent.NodeTemplateID;
        var ti =  PageTemplateInfoProvider.GetPageTemplateInfo(templateID);
        CMS.Helpers.RequestStockHelper.Add("templateName", ti.CodeName);
    }
    templateName = ValidationHelper.GetString(RequestStockHelper.GetItem("templateName"), "");      
}  
</script>
<%=templateName%>
