How can I determine the Calender drop-down of DateTimePicker is currently opened or closed ?

推荐答案

您要处理OnDropDown和OnCloseUp事件以及这些事件，控制变量的值，如下所示:

You want to handle the OnDropDown and OnCloseUp events and in those events, control the value of a variable, something like this:

bool m_droppedDown = false;

private void OnDTP_DropDown()
{
   m_droppedDown = true;
}

private void OnDTP_CloseUp()
{
   m_droppedDown = false;
}
