Animatable.FreezeCore Method (Boolean)
Makes this Animatable object unmodifiable or determines whether it can be made unmodifiable.
Assembly: PresentationCore (in PresentationCore.dll)
true if this method should simply determine whether this instance can be frozen. false if this instance should actually freeze itself when this method is called.
Return ValueType: System.Boolean
If isChecking is true, this method returns true if this Animatable can be made unmodifiable, or false if it cannot be made unmodifiable.
If isChecking is false, this method returns true if the if this Animatable is now unmodifiable, or false if it cannot be made unmodifiable, with the side effect of having begun to change the frozen status of this object.
Notes to Implementers:
Classes that derive from Animatable must override this method when the class contains data that is not stored using dependency properties.
A typical implementation would call the base implementation, then call the static Freeze method on all Freezable typed properties that the class contains, returning true only if all properties were frozen (or could have been frozen, in the case of passing through a false value for isChecking).
