推荐答案

实际上，DataTemplate用于在ItemsControl(如列表框，列表视图或组合框)中显示项目.

并将此DataTemplate应用于ContentPresenter或ContentControl.因此，ContentPresenter是用于保存DataTemplate的容器，而ItemsPresenter是用于保存ItemTemplate的容器.因此，这就是您的按钮因为仅显示而无法工作的原因.

Actually DataTemplate is used to display the items in an ItemsControl like listbox, listview or a combobox.

And this DataTemplate is applied to the ContentPresenter or ContentControl. So you a ContentPresenter is a container for holding the DataTemplate and an ItemsPresenter is a container for holding the ItemTemplate. So that''s why your button won''t work because its only getting displayed.
