title: Disable filtering on a Dynamic Data list view
body: <p>I have an entity set of <em>NotificationTemplates</em>, and each one of these has a collection of zero-many <em>SmsTemplate</em> entities.  When editing or viewing a <em>NotificationTemplate</em>, I have a link to <code>View SMS Templates</code>.  That link takes me to a List view for the <em>SmsTemplates</em> entity set, filtered for the <em>NotificationTemplate</em> I was viewing.</p>
  
  <p>How can I prevent the user changing this filter to show <em>SmsTemplates</em> for another <em>NotificationTemplate</em>?  That is, I want the filter, but it must be read only.  The drop-down just mustn't drop down, it must just display the name of the <em>NotificationTemplate</em> that these SmsTemplates belong to.  To view SmsTemplates for another <em>NotificationTemplate</em>, the user must click <code>View SMS Templates</code> from that other template.</p>
