MahApps NumericUpDown make up down buttons bigger

Question

I'm working on a wpf project that uses the Mahapps NumericUpDown. In order to make it more touch friendly, I'ld like to make the up and downbuttons a bit bigger.

I've tried setting the height and width bigger of the whole numericUpDown control, but this only makes the buttons height bigger (the width seems to be fixed)

I also tried wrapping the NumericUpDown in a viewbox. This makes everything bigger. The problem is that the numbers in the textbox are also bigger, making it look very alien to the rest of the controls on the screen.

Any ideas on any better solutions?

Answer 1

I don't know when it was added, but the NumericUpDown Control has a UpDownButtonsWidth Property:

<mah:NumericUpDown
    UpDownButtonsWidth="60"/>

The + and - buttons get wider accordingly.

Answer 2

I am the developer of NumericUpDown in MahApps.

A solution is to change in NumericUpDown.xaml the Path.Data in PolygonUp and PolygonDown or to change the Contentent of PART_NumericUp and PART_NumericDown.
