Yes, you can easily do that, just set SmallChange property to 0.25 and Maximum to 1. Also, if you want to restrict the user from entering his own number, you can set IsEditable property to false. Moreover, if you want to clarify the number inside the numeric, you can also set any string value in the CustomUnit property which will appear after the number. You can use the following code snippet to achieve your goal. I hope this will solve your issues, and thank you for contacting us.
