How to increment and decrement a value when UseNullOption is true in UpDown control?

Control: UpDown |

By default, we cannot increment or decrement the value by up and down buttons when Value is Null. Increment or decrement a value from the null in UpDown can be achieved by handling PreviewMouseDown, PreivewKeyDown and MouseWheel events. In this sample, we have reset the value to 0(zero) using the events mentioned above. The following code has explained the same.
