I would like a button beside the picker that indicates that the picker is a clickable "dropdown". But how could I open the picker when the button is clicked?

推荐答案

您可以命名选择器(例如myPicker)并调用其Focus事件.确保在调用myPicker.Focus()时位于主线程上

You can name the picker (e.g. myPicker) and call its Focus event. Do make sure that you're on the main thread at the time you're calling myPicker.Focus()
