SharePoint 2007 – Hide calculated fields in display form

Leave a reply

The following steps describe how to hide calculated columns when viewing an item in a SharePoint 2007 list using SharePoint Designer 2007 and jQuery.

1. Download the latest version of jQuery.
2. Upload the file to a document library in your SharePoint site.
3. Open your site with Microsoft Office SharePoint Designer (a free download).
4. Open ‘default.master’ – found under _catalogs/masterpage (Master Page Gallery).
5. Add <script type=”text/javascript” src=”url to your/jquery-1.6.2.min.js”></script> just above the </HEAD> tag.
6. Save and publish this file.
7. Open ‘DispForm.aspx’ for your list – found under Lists/your list name/
8. Add the following script at the bottom of the ‘PlaceHolderMain’ content zone:

   <script type="text/javascript"> $(document).ready(function(){ $("[id=SPFieldCalculated]").parent("tr").css("display","none"); }); </script>

   
9. Save this file.

I stumbled upon this technique when a customer did not want the 8 calculated columns used as filtering criteria in a view visible when viewing the item.
