How to check if the document already exists in a Link Item Collection

Vote:
 

I'm using EPiServer CMS 7.5. I have a block that has a LinkItemCollection property.

public virtual LinkItemCollection LinkList { get; set; }

The user can drag-and-drop any document from the Assets pane into the Link Item Collection. How do I prevent the user from adding a document that already exists in the Link Item Collection while in forms edit mode?
