What does AdornedElementPlaceholder exactly do when we use it in validation controlTemplate?

人走茶凉 提交于 2020-07-02 11:59:09
问题 After going through several articles and examples showing usage of AdornedElementPlaceholder i am still confused that what is the exact functionality it incorporates to xaml validation? 回答1: If you use Validations you need to show the user where (and what) failed to validated and that’s where AdornedElementPlaceholder comes into play.
