I want to hide or make some fields read only on editform.aspx. I follwed the example on this page, but without deliting the "original" webpart list. I hide the original webpart and created a new custom list from the original list. Then i was able to apply xsl on the custom list to hide or to make the field "read only". Unfortunately the recurring events stopped working or where totaly messed up. Some times i've got error messages when I clicked on specific event in calendar view. The calendar list works fine and the fields are hidden or disabled in "Edit mode" when the event is not recurring. My question is. Is there any other way to hide or disable the items for specific security group or sharepoint group on calendar list?
Please see the commercial program on this page to see what i am looking after.
