I'm trying to add a link that starts with the protocoll "notes://" to a URL list and in a standard rich text field but only get "the url is not valid" How can i make sharepoint 2010 understand that this link is valid?

Can i do some kind of configuration to make SP 2010 understand that this type of link is valid? Or do i need to program a custom field type in order to make Sp accept this type of link?


The validation SharePoint uses on that column is hard-coded. I can think of at least two ways to achieve a similar effect:

1) Use a custom column type you define in VS


2) Use a regular text field for entering the URL. Then use a calculated column to concatenate strings around the URL to make it a clickable link. Then display the calculated column...

  • Option 2 only works if you select "Number" as resulting return type of the calculated field and only the Gods know why this is that way. – Shihan May 13 '15 at 8:06
