CornerRadius with IntegerUpDown

[Maxim-Paluh]

I tried different ways to modify IntegerUpDown to get rounded edges.
Here are my observations:
IntegerUpDown -> CommonNumericUpDown -> NumericUpDown -> UpDownBase -> InputBase -> InputBase -> Control

NumericUpDown has a Style that indicates that the control consists of a ButtonSpinner x:Name="PART_Spinner" and a WatermarkTextBox x:Name="PART_TextBox"
(in the NumericUpDown class it is specified that [TemplatePart( Name = PART_TextBox, Type = typeof( TextBox ) )])
Everything is clear here

WatermarkTextBox -> AutoSelectTextBox -> TextBox
WatermarkTextBox also has its own Style and defines a new Template for it.
I've been trying to change different Templates in different places throughout the day, but I still can't get the result I want

Hi,
From what I can see, there is no direct way to modify the CornerRadius of a NumericUpDown.
We will try to add a property to easily modify this.

In the meantime, if you have access to the source code, here's how a CornerRadius can be set:
In file Xceed.Wpf.Toolkit/ButtonSpinner/Themes/Aero2.NormalColor.xaml,
In style targeting : x:Type local:ButtonSpinner, in the ControlTemplate for x:Type local:ButtonSpinner,
The first Border can have a CornerRadius of 10:

This will force a 10 CornerRadius on the 4 sides, but only visible on the lest side since the Up/Down buttons are over the right part.

Then, in the same ControlTemplate, the RepeatButton PART_IncreaseButton has a set style : remove it. then add it's style with a TopRight corner radius of 10:

In the same way, for PART_DecreaseButton, you can remove its style and add a new one with a bottomRight Corner Radius:
