CompositionPropertySet CompositionPropertySet CompositionPropertySet CompositionPropertySet Class
Definition
Stores values as key-value pairs. CompositionPropertySet s are CompositionObject s that allow storage of key values pairs that can be shared across the application and are not tied to the lifetime of another composition object. CompositionPropertySet s are most commonly used with animations, where they maintain key-value pairs that are referenced to drive portions of composition animations. CompositionPropertySet s provide the ability to insert key-value pairs or retrieve a value for a given key. For more information on using CompositionPropertySet with animations, see the Animations Overview page.

Examples
void CreatePropertySet()
{
// Create the CompositionPropertySet and insert a scalar value
CompositionPropertySet sharedPropSet = _compositor.CreatePropertySet();
sharedPropSet.InsertScalar("offsetChange", 50f);
// Reference value in CompositionPropertySet in an Expression
ExpressionAnimation expression =
_compositor.CreateExpressionAnimation("this.Target.Offset.X + shared.offsetChange");
expression.SetReferenceParameter("shared", sharedPropSet);
}
void PropertySetRetrieve(CompositionPropertySet propertySet)
{
// Retrieve the value of key in a CompositionPropertySet
float tempOffset;
propertySet.TryGetScalar("offsetChange", out tempOffset);
}
Remarks
CompositionPropertySet does not support a delete function – ensure you use CompositionPropertySet to store values that will be shared across the application.
Note
Inserting a new value into a CompositionPropertySet for a key that already exists with overwrite the old value with the new one.
