Freezable::CanFreeze Property
Gets a value that indicates whether the object can be made unmodifiable.
Assembly: WindowsBase (in WindowsBase.dll)
Property Value
Type: System::Booleantrue if the current object can be made unmodifiable or is already unmodifiable; otherwise, false.
This method implementation uses the FreezeCore method with isChecking set to true to determine whether a Freezable can be made unmodifiable. To modify the way this property behaves in a derived class, override the FreezeCore method.
This example shows how to make a Freezable read-only by calling its Freeze method.
You cannot freeze a Freezable object if any one of the following conditions is true about the object:
It has animated or data bound properties.
It has properties that are set by a dynamic resource. For more information about dynamic resources, see the Resources Overview.
It contains Freezable sub-objects that cannot be frozen.
If these conditions are false for your Freezable object and you do not intend to modify it, consider freezing it to gain performance benefits.
The following example freezes a SolidColorBrush, which is a type of Freezable object.
For more information about Freezable objects, see the Freezable Objects Overview.
