Why WPF controls don't have Tag property?

Question

I think all WinForm controls have a Tag property which I found very convenient on occasions. However, this Tag property seems to be gone for WPF controls like DataGrid. Can anybody explain why? Is there a better way in WPF to accomplish this?

Answer 1

WPF controls do have a Tag-property (Because of the base-class). However with the concept of the DataContext, the tag-property is not anymore very important.
