DependencyProperty.OverrideMetadata() 是否也覆盖了 PropertyChangedCallback?

最佳答案

The supplied metadata is merged with the property metadata for the dependency property as it exists on the base owner. Any characteristics that were specified in the original base metadata will persist; only those characteristics that were specifically changed in the new metadata will override the characteristics of the base metadata. Some characteristics such as DefaultValue are replaced if specified in the new metadata. Others, such as PropertyChangedCallback, are combined.
