CheckAccess Determines whether the calling thread has access to this object. (Inherited from DependencyObject.)
Clear Removes all items from the PresentationFrameworkCollection<(Of <(T>)>). (Inherited from PresentationFrameworkCollection<(Of <(T>)>).)
ClearValue Clears the local value of a dependency property. (Inherited from DependencyObject.)
Contains Determines whether the PresentationFrameworkCollection<(Of <(T>)>) contains a specific value. (Inherited from PresentationFrameworkCollection<(Of <(T>)>).)
CopyTo(array<T>[]()[], Int32) Copies the elements of the PresentationFrameworkCollection<(Of <(T>)>) to an Array, starting at a particular Array index. (Inherited from PresentationFrameworkCollection<(Of <(T>)>).)

Remarks

TransformCollection is used by TransformGroup to store Transform child elements. Transform itself is an abstract type, so this means that the items in the collection will typically be one of the following classes defined by Windows Phone:

The XAML syntax for properties that use a TransformCollection is an example of an implicit collection syntax, where you can omit an actual TransformCollection object element, as well as the TransformGroup.Children property element. Instead, you generally include one or more Transform derived elements as child elements of a TransformGroup. (Explicitly including a TransformCollection object element is permissible XAML syntax and might be useful if you intend to name the collection in XAML and manipulate its contents programmatically.)

Transforms in a TransformCollection are applied in the order that they appear in the collection, so the index order of each transform in a TransformCollection is meaningful.
