title: How to conditioanlly hide group header in crystal report based on a column value in details section
body: <p>I hope some one must have dealt this situation before.</p>
  
  <p>I have a crystal report and on that report I have different sections including headers ,detail and footer. I'm displaying parts related information on details section and description is one of the fields thats being displayed.</p>
  
  <p>So now based on part's description(in detail section)I have to display some text on the page header. So I have to look for part's description for every single part ,and if even a single part has the given description out of all the parts I have to print a message on report header.</p>
  
  <p>My assumption is to use conditonal suppress option at the page header section, but not sure how to check for values from details section at the page header level.</p>
  
  <p>Any help will be highly appreciated.</p>
  
  <p>Thanks
