SPContentType.Hidden property

Gets or sets whether the content type is hidden on the list’s New menu.

Namespace:  Microsoft.SharePoint
Assembly:  Microsoft.SharePoint (in Microsoft.SharePoint.dll)

'Declaration
Public Property Hidden As Boolean
    Get
    Set
'Usage
Dim instance As SPContentType
Dim value As Boolean

value = instance.Hidden

instance.Hidden = value

public bool Hidden { get; set; }

Type: System.Boolean
true if the content type is hidden on the list’s New menu; otherwise false.

You can use this property to specify that a content type be hidden. Hidden content types are not displayed on the New menu for list views. Therefore, users cannot create new items of that content type from the list. The content type is still displayed everywhere else in the user interface.

When you modify the value of this property, your change does not take effect until you call the Update() method. Calling this method commits all modifications to the content type definition back to the SharePoint database.

The following console application prevents one of the content types available in a document library from appearing on the library’s New menu.
