How to close the dropdown from DateTimePicker without selecting any date?

Question

How to close the dropdown from DateTimePicker without selecting any date? Visual studio, .NET, C#, WinForm. Within the code, I have to interact with the user, I'm in the DropDown event of the DateTimePicker, to my question he has to answer yes or no, if NO, I simply want the date selection menu to close. I tried another approach, with MouseDown on the DTP control but the DropDown is no longer executed, does anyone have another idea? I need the user in front of several DTPs to choose the DTP to modify, but if he chooses wrongly, to be able to switch to another one without making 1 additional click to select a date that does not needs. It's possible? THX.
