I have a custom list with a field called as participants (Multi person column). I want that, only users who are creator, in participants list or owners of site should be able to view the details of the item. That said, if I try and paste the direct URL to list item as
only above users should be able to view the DispForm.aspx and others should either be redirected to another page or shown a custom access denied message. I remember there is a tag in SharePoint with which we can do it via SharePoint Designer. But unable to recall or find anything. Any help would be appreciated. I can edit page only with SharePoint Designer.
