| Item[Int32] | Gets or sets an object at the specified index. This property is implemented to support the IList interface. Inherited from DynamicCollectionBase. |
| ObjectSpace | Returns the Object Space used to manipulate the collection’s objects. Inherited from DynamicCollectionBase. |
| ObjectType | Returns the type of objects that the Objects collection can contain. Inherited from DynamicCollectionBase. |
| Sorting | Specifies the list of SortProperty objects that specify the sort order for the collection. Inherited from DynamicCollectionBase. |
| SyncRoot | Gets an object that can be used to synchronize access to the collection. This property is implemented to support the ICollection interface. Inherited from DynamicCollectionBase. |
| TopReturnedObjectsCount | Specifies the maximum number of objects that can be retrieved from the collection. Inherited from DynamicCollectionBase. |
Methods
| Name | Description |
|---|---|
| Add(Object) | Adds the specified object to the collection. This method is implemented to support the IList interface. Inherited from DynamicCollectionBase. |
| Clear() | Removes all objects from the collection. This method is implemented to support the IList interface. Inherited from DynamicCollectionBase. |
| Contains(Object) | Checks whether the collection contains the specified object. This method is implemented to support the IList interface. Inherited from DynamicCollectionBase. |
| CopyTo(Array, Int32) | Copies the collection to the specified array. This method is implemented to support the ICollection interface. Inherited from DynamicCollectionBase. |
| Dispose() | Disposes of all resources this DynamicCollectionBase object uses. This method is implemented to support the IDisposable interface. Inherited from DynamicCollectionBase. |
| Equals(Object, Object) static | Determines whether the specified object instances are considered equal. Inherited from Object. |
| Equals(Object) | Determines whether the specified object is equal to the current object. Inherited from Object. |
| GetHashCode() | Serves as the default hash function. Inherited from Object. |
| GetType() | Gets the Type of the current instance. Inherited from Object. |
| IndexOf(Object) | Determines the index of the specified object in the collection. This method is implemented to support the IList interface. Inherited from DynamicCollectionBase. |
| Insert(Int32, Object) | Inserts the specified object into the collection at the specified position. This method is implemented to support the IList interface. Inherited from DynamicCollectionBase. |
| MemberwiseClone() protected | Creates a shallow copy of the current Object. Inherited from Object. |
| ReferenceEquals(Object, Object) static | Determines whether the specified Object instances are the same instance. Inherited from Object. |
| Reload() | Clears the collection. The FetchObjects event will occur on the next access to this collection. Inherited from DynamicCollectionBase. |
| Remove(Object) | Removes the specified object from the collection. This method is implemented to support the IList interface. Inherited from DynamicCollectionBase. |
| RemoveAt(Int32) | Removes an object from the specified index in the collection. This method is implemented to support the IList interface. Inherited from DynamicCollectionBase. |
| ToString() | Returns a string that represents the current object. Inherited from Object. |
Events
| Name | Description |
|---|---|
| FetchObjects | Occurs when the DynamicCollection contents are accessed for the first time, when this collection is reloaded, or its Criteria and Sorting parameters are changed. Handle this event and set the FetchObjectsEventArgs.Objects argument the DynamicCollection contents. |
| ListChanged | Occurs when the collection contents are changed. This event is implemented to support the IBindingList interface. Inherited from DynamicCollectionBase. |
| Loaded | Occurs after the collection was populated with objects. Inherited from DynamicCollectionBase. |
