Properties

  Name Description
Public property Content When overridden in a derived class, gets a ModelProperty representing the item's ContentPropertyAttribute. (Inherited from ModelItem.)
Public property Context Gets an object that contains contextual information about the designer this ModelItem was created for. (Inherited from ModelItem.)
Public property Count When overridden in a derived class, gets the count of items in the collection.
Public property Events When overridden in a derived class, gets the public events on this object. (Inherited from ModelItem.)
Protected property IsFixedSize When overridden in a derived class, gets a value indicating whether the collection is a fixed size.
Public property IsReadOnly When overridden in a derived class, gets a value indicating whether the collection can be modified.
Protected property IsSynchronized When overridden in a derived class, gets a value indicating whether the collection is synchronized.
Public property Item When overridden in a derived class, gets or sets the item at the specified index. This is a dependency property.
Public property ItemType When overridden in a derived class, gets the type of object the item represents. (Inherited from ModelItem.)
Public property Name When overridden in a derived class, gets or sets the name or ID of the item. (Inherited from ModelItem.)

Public property Properties When overridden in a derived class, gets the public properties on this object. (Inherited from ModelItem.)
Public property Root When overridden in a derived class, gets the item that is the root of this tree. (Inherited from ModelItem.)
Public property Source When overridden in a derived class, gets the property that provided this value. (Inherited from ModelItem.)
Protected property SyncRoot When overridden in a derived class, gets an object that can be used to synchronize this collection.
Public property View When overridden in a derived class, gets the visual or visual3D representing the UI for this item. (Inherited from ModelItem.)

Remarks

ModelItemCollection derives from ModelItem and implements support for a collection of items. ModelItemCollection defines a static attached property name Item. This property is returned from the Properties enumeration of the collection, in addition to any properties defined on the collection. The Item property represents all the items in the collection and is defined as type IEnumerable of ModelItem. All items in the collection have their Source property set to this property. The property’s metadata marks it non-browsable and non-serializable. The Item property is a "pseudo" property because it is not actually set on the model. The value it points to is the ModelItemCollection itself.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
