public:
 abstract bool CanResetValue(System::Object ^ component);
public abstract bool CanResetValue (object component);
abstract member CanResetValue : obj -> bool

Remarks

Notes to Inheritors

When overridden in a derived class, this method looks for a DefaultValueAttribute. If it finds one, it compares the value of the attribute with the property's current value. It returns true when the default value does not match the property's current value. If this method cannot find a DefaultValueAttribute, it looks for a "ShouldPersistMyProperty" method that you need to implement yourself. If this is found, CanResetValue(Object) returns what "ShouldPersistMyProperty" returns. Otherwise, it looks for a "ResetMyProperty" method that you need to implement yourself. If this is found, CanResetValue(Object) returns true. If it cannot find a DefaultValueAttribute, a "ShouldPersistMyProperty" method, or a "ResetMyProperty" method, then it returns false.
