If I understood your requirement correctly, you are looking for a control that allows entering only numeric values and also consists of a dropdown with a list of numbers.
If it so, then C1ComboBox is the control for you.
You may set "DropDownStyle" and "AutoCompleteSource" properties to "Default" and "ListItems" respectively.
You may find more information about the control here:
I have also attached a sample application for your reference.
Please do let me know if I misunderstood your requirement or if this does not meet your requirement.
Thanks & Regards
