Please help me on the DateTimePicker Control

[joko]

1. How to show the calender dropdown on DateTimePicker control using the keyboard? (Is there a command like the combobox control - combo.droppeddown=true - to show the dropdown list)
2. How can I make DateTimePicker control to have flat appearence?
3. How to make DateTimepicker Control to accept Null/empty Value?
4. I bind the DateTimePicker to a Dataset. When I Edit the value, why the time portion didn't change?
