CheckBox CornerRadius not working

[PJonHar]

I have tried to add a CornerRadius to the CheckBox control but it does not work?
Am I doing something wrong?

MahApps.Metro version: v2.4.3
Windows build number: Win10 1903 [Version 18362.1256]
Visual Studio: 2019 18.6.0
Target Framework: .Net 4.8

Hi @PJonHar

seems like it is currently not supported. I will add it if @punker76 gives me a 👍 .

@punker76 I can think of three possible solutions. Please mark the one you like most and I'll make a PR for it:

• Change the Recangle to Border and use the ControlsHelper.CornerRadius-Property which is already available
• Keep the Rectangle and add CheckBoxHelper.CheckMarkRadius-Property. This will then control both RadiusX and RadiusY of the Rectangle
• Keep the Rectangle and add two CheckBoxHelper.CheckMarkRadius-Properties (one for X and one for Y. The user can control the appearance in more detail but needs to set two properties everytime.

My favorite is option 2 I think

Happy coding
Tim

Hi Tim,

I think that changing the Rectangle to a Border will be the cleanest solution ? As you say, the ControlsHelper.CornerRadius-Property is already available.

Cheers.

mhh not necessarily. If you look into the Style you will notice that it is already used by another Border:

MahApps.Metro/src/MahApps.Metro/Styles/Controls.CheckBox.xaml

Lines 25 to 30 in 711f987

	<Border x:Name="RootBorder"
	Background="{TemplateBinding Background}"
	BorderBrush="{TemplateBinding BorderBrush}"
	BorderThickness="{TemplateBinding BorderThickness}"
	CornerRadius="{TemplateBinding mah:ControlsHelper.CornerRadius}"
	SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" />

another point is that you control all CheckMark-related things in the CheckBoxHelper. So you why not the CornerRadius?

I used snoop and found this if it helps?
