NumericUpDown Control in C#

Question

Is it possible to enter and display the text in the NumericUpDown control in windows forms application?

 

I have a NumericUpDown control which should accept numbers from 0 to  1000 and it should allow me to enter the text "NOW" and it should be validated and maintain the same value after the leave event of the contorl. Issue is when I tab out from the control to some other control it is clearing the value and setting the value to 0.

 

Please help me on this  whether it is possible to achieve or not.
